OTTO HERRESCombined Metals Reduction Co.Stockton, UtahDear Mr, Herres:In reply to your letter of March 14th addressed to Mr, C. J.Peterson, we take pleasure in advising that arrangements havebeen made for a full-page, two-color Eimco advertisement, asper the enclosed reprint, to appear in the April 1940 issue ofThe Mines Magazine.We fully appreciate the great industrial purchasing powerrepresented In the membership of the Colorado School of MinesAlumni Ass'n., but our limited advertising appropriation does notpermit advertising in all of the publications in which we wouldlike to be represented. We do feel, however, that an advertisementin this special issue should be very valuable and appreciateyeur having called it to our attention.FROM THE WILDSFrom LOUIS BARTHOLOMEES, '32Very truly yours.The Eimco CorporationF. B. GARRAHAN, Mgr., Sales Promolio?iFrora this isolated corner of the Orient all seems well. Atthis camp are Johnny Barnes, '34 and Dick Spencer, '34. Notfar away is Lepanto where John Carpenter, '35, has invaded ahive of Arizonians to be the only Colorado miner there, herecently transferred from the Hong Kong mines of the samecompany.Do not get into Baguio but once in a long while but when theredo stumble across some of the boys. Have received severalnotices of meetings in Baguio but have not been able to attendany of them as yet, I still have hopes.I hope that 1940 will be the best year yet for the AlumniAssociation,Suyoc Consolidated Mining Company, Box 218, Baguio, Philippines.FROMBRAZILFrom FRANCIS N.

I plan to return to Denverfor a few months, I remember your saying there is a dearth ofPetroleum Engineers in Colorado. I presume you know I receivedmy license to practice in Colorado, effective January I,1940?I am staying in a mountainous place called "Pogos de Caldas"in Minas Gerais. I hike around a bit, and am also taking the"steam" baths which are famous in this locality.

Bend that V-belt whileyou grip its sidewalls between your fingers and your thumb. You willfeel the sides of the belt bulge out—as shown in figure 1 on the left.Clearly, that out-bulge gives the belt a shape that does not fit its sheavegroove.Nowlook at figure 2, There you sec what happens when you benda belt that is built with the patented concave sides. You get a similarchange in sidewall shape—but what a different result! V"BcltThe precisely engineered concave side becomes perfectlystraight. There is no outbulge:—the full side-width ofthe belt uniformly grips the sheave groove wall. Thismeans uniform wear—longer life.

te p v i c eu m n i _4 d d o c i u t i o nFRANK C. BOWMANThirty Years—not long when comparedwith the life of many publications.Just a good start. It is timeenough though to show whether yourexistence is justified by the servicerendered. Serving one master may bedifficult in itself but when the taskis multiplied many times by the differentbranches of the mineral industriesand their large variety of interests,then it presents a problem not so easyef solution. That industry requiresengineers with at least the fundamentalsof every branch of engineering,and with this goes a large diversityof interest.The reader of any magazine has aright to expect and to find materialof interest in every number otherwisehe will not give it his attention forany length of time. It is fortunatethat the broad scope of the mineralindustries furnishes a large varietyof fascinating material of interest toalmost everyone from the layman tothe engineer or even the specialist.In the early days "Mines" attemptedto cover the principal branchesof engineering, including that ofcivil, electrical, mechanical, miningand metallurgical. Later they confinedtheir efforts to training engineersfor the mineral industries whichrequired, broadly speaking, mining,By i=RANK C. BOWMAN. '01Editor and Publication Directorgeological, chemical, metallurgical,and petroleum engineers. Today wefind that "Mines" is the only educationalinstitution in the world devoted• exclusively to the training of engineersfor the mineral industries.Thirty 5'ears ago a small group of"Mines Men," members of the ColoradoSchool of Mines Alumni Association,had a vision of a greater"Mines," built through the educationof men to serve the mineral industries.They believed that to assist in buildinga greater "Mines," a publicationwas needed to not only keep "MinesMen" in closer contact with the needsand service of the institution but toget the story to others who wereinterested in the progress and growthof the industry. It was this need thatfurnished the impetus to create "MinesMagazine," first a modest 16-pagepublication filled mostly with collegenews that went to a few loyal "MinesMen" readers.With the growth of "Mines" andthe broadening of its scope, it wasonly a natural sequence that "MinesMagazine" should expand and increaseits coverage. "Mines Men"became important factors in mining,geology, geophysics, chemistry, metallurgy,petroleum production and refining,research and invention, manufacturing,sales and distribution, education,and many of the various ramificationsof the mineral industries inthis country and all over the world.They lead in the creation of new processesand methods for utilizing ourvast mineral resources.During this period of progress"Mines Magazine" told the entireworld what "Mines Men" were doing,and how they were serving themineral industries. It furnished theties so necessary to keep this scatteredgroup of workers in touch with eachother and the institution that had instilledin them the fundamentals thatwere needed for great accomplishment.These men wanted to knowwhat was going on at home; what wasbeing done in the many branches ofthe mineral industries; and whatprogress was being made in education,in new methods, in research, in inventionand the manufacture of newequipment. Naturally they looked to"Mines Magazine" to keep them informedon all this progress. In attemptingto meet these requirements"Mines Magazine" grew from astrictly college publication, into aclass all its own; one that cooperateswith the man in the field, the manin the factory, the raan who is interestedin the mineral industries becauseit is essential to the progress of civilization,and to the young man at"Mines" who is learning how to carrythe banner of accomplishment on andupward.In celebration of the thirtieth anniversaryof "Mines Magazine" weknow of no more appropriate waythan to dedicate this number to theColorado School of Mines AlumniAssociation. An attempt has beenmade to convey to the reader a pictureof the accomplishments of "MinesMen" and the important part theyhave played in bringing our mineralindustries to its present importantstate of usefulness in making our highstandards of living possible. It is onlythrough the hearty cooperation of ourmany loyal friends that this numberhas been made possible. To these weextend our sincere appreciation forthe support and courage they havesupplied.FRANK J. NAGEL, '03Secretary Alumni AssociationByE. J. BROOK, '23President, Alumni AssociationYour Alumni Association is aunique organization. Based uponcollective effort, it is composed ofmembers fundamentally individualisticin attitude and action. The entiremembership, scattered to the farcorners of the earth, is numericallyinferior to a single graduating classfrom some of our larger universities.Despite these contradictory factors,which are the enigmas of similar organizations,our association shows aremarkable strength and solidarity ofpurpose.The actual work so well as determinationof policies of the associationare performed by officers who receiveno pecuniary remuneration fortheir services. These men withoutexception are relieved of the responsibilitiesof business life neither hygreat inherited wealth nor bv indifferenceto personal security. Theyaccept responsibilities to their fellowmembers by their own initiative andindustry in addition to their ordinarybusiness pursuits. Their reward ispride of accomplishment in unselfishservice to the organization.Your Alumni Association is neithera technical society nor a fraternal organization.The broad purpose ofthe organization is hased upon serviceto the graduates and former studentsof Mines, regardless of their stationsin life or the particular occupationalpursuits they may be following fora livelihood.It is to elucidate more fully a trueconception of that service that thisparticular issue of Mines Magazineis dedicated to Mines Men and theirAlumni Association. Through thepages of the publication your oificersare endeavoring to reveal the tremendouspotential possibilities yourorganization possesses to be a vitalfactor in the life of each Alumnus.Your officers believe that the serviceyour Association can perform forMines Men is expressed in the desireon our part to keep the fires of friendshipsformed at Mines brightly burning.It is expressed in the desire tosafeguard and enhance the reputationof our Alma Mater as a practical,economic value to the degree of eachAlumnus; it is expressed in our desireto perpetuate the ideals and traditionsof our college in the studentbody.This service finds expression in ourE. J. BROOKhope to help each Mines Man reachhis maximum capabilities and earningcapacity through our CapabilityExchange. The mistaken idea that aman should avail himself of this serviceonly when "out of a job" is atvariance with its true function. Thatfunction is to provide better positionsfor employed Mines Men as they becomequalified through experience andpost-graduate training. This servicecannot be effective unless our memberscooperate in advising theCapability Exchange of "positionsavailable" which some Mines Mencan fill, so well as thinking of theservice only when the occasion "positionwanted" arises.Your Association believes it hasmade a definite contribution towardhelping to solve the perplexing youthproblem in a small way through sponsoringAlumni Scholarships, Thesescholarships make it possible forworthy young men to obtain a collegetraining, who otherwise wouldbe denied this opportunity. The sumour members have contributed to theStudent Loan Fund has greatly aidedthis worthwhile project. As the natureof this program becomes moreapparent to our membership, we arecertain the Student Loan Fund willreceive the unanimous support of ourgroup.The officers of your association areconfident of the cooperation of ourmembers in lending a "helping hand"to the young graduates in their tryingperiod of adjustment after enteringbusiness or professional life. The oldidea that such action was a sentimentaldisplay of initiative-killingpaternalism has been superseded byan interest in the welfare of our"new alumni" by the older members.The latter do not feel that their ownstruggles and vicissitudes shouldnecessarily be duplicated by the newgeneration. We believe the Minesgraduate of today is a splendidlytrained youth who is worthy of ourinterest and help.The progress and welfare of ourAlma Mater is of more concern tothe Alumni than a mere sentimentalinterest. One of the chief functionsof our group is to extend a fullmeasure of support and cooperationto furthering the interests of theschool. The Association can andshould render valuable assistance inhelping the administration at Minessolve such problems in which theschool cannot effectively engage. TheAssociation believes that this aid tothe school is not only a duty but avaluable asset to the economic valueof the degree held by the individualalumnus.The scope of the Alumni Associationcannot be covered in a few paragraphsor in a magazine. Its theoreticaloperation, shown in artisticallydelineated charts, is valueless unlessthose operations be proved by actionand results. To be understood, itsproblems, its frustrations, its triumphsmust be shared by tbe membership.Interest in our progress raust extenddown "to the grass roots", to the individualmember, if we are to accomplishour mission.Today, as never before, j'Our Associationneeds the name of each MinesMan on tbe membership roster. Itexists not as an agency to carrycollegiate "Rah! Rah!" into the businessworld but as an instrument tohelp each Mines Man help himself.Your Association offers all nonmembersthe privilege of identifyingthemselves with our organization.The Colorado School of MinesAlumni Association should and canbe a definite asset to each member.It should be worthy of the gambleof the price of a membership toeach Mines Man. Throughout theyears an agency has been createdto serve the alumnus in a broad scopeof activities rightfully the function ofan alumni organization. It can begreat, not through any single factorbut through an integration of all ofthem. It can be as great as the membershipdesires it to be!160 THE MINES MAGAZINE • APRIL 1940THE MINES MAGAZINE * APRIL 1940 16t

ALUMNI ASSOCIATION ENDOWMENTWILLIAMDE WITTThe Colorado School of MinesAlumni Association is probably themost unique organization of its kindin that it is not subsidized and controlledby the College from which itoriginated. It was organized bygraduates of the Colorado School ofMines in May 1895 and it was incorporatedunder the laws of theState of Colorado in 1935 by its dulyelected officials. It is an independentorganization, receiving no gratuitiesof any kind. It receives the supportof Mines men everywhere and itcommands the respect of everj'one.It voices the views of its members onall questions pertaining to the Schoolof Mines. It carries on a continuousservice for its members to elevatethem in their professions. It is buildingthe Colorado School of Mines tostill greater heights. It maintainsthat no Mines man is so great thathe cannot be greater and also thatthe Alma Mater, no matter howgreat it may become, can always beimproved. It is an active militantorganization that does not "pass thebuck." It recognizes that certainwork must be done and has set aboutto do it. It has taken the responsibilityof improving the Alma Materas well as improving the status of theAlumnus. It is making steadyprogress in these matters and eachyear finds that it has more accomplishmentsto its credit.There is no need for me to set outhere the growth of the Aiumni Association,nor of its Mines Magazine,nor of its Capability Exchange, norof the influence of the Associationwith the Colorado Legislature andthe general public in all matters concerningthe School of Mines andhigher education in Colorado.The Alumni Association is proudof the School of Mines—it is proudof the graduates and the record theyhave made in the profession, it isproud of the Administration, Facultyand Student Body. The AlumniAssociation is always on the job advisingwith trustees regarding policiesaffecting the school—conferring withthe faculty regarding improving thecurriculum—and assisting students invarious waj's. The Alumni Associationsestablished a Students' LoanFund which has been of benefit tomany students, it has raised moneyto help pay off the indebtedness onBrooks Field, it has two members onthe Athletic Board of Control at theByC. LORIMER COLBURN, '07Cha irman Alumni AssociationEndowment CommitteeSchool and has helped the athleticsituation in many ways.In addition to all the activitiesmentioned above the Aiumni Associationhas organized and is fosteringa Foundation for the School. Thismove was made by a nearly unanimousC. LORIMER COLBURNvote of the members of the Association.What other Alumni Associationof its own volition and in itsown independent way has taken overtbe Herculean task of creating aFoundation for its AlmaMater?The Colorado School of MinesFoundation was established by theAlumni Association on May l7th,1928. Since that time $7,000 incash has been put into the Foundationtreasury. The first subscriptionwas a $1,000 gift, secured by W. D.Waltman and presented to theFoundation at the tirae of its organization.All other gifts were ofsmall sums, mostly $2 or $3 contributionsmade from time to time bymembers of the Alumni Association.Seven thousand dollars donatedover a 12-3'ear period is not an impressivesum but it was given by manyMines Men and it is a substantialstart.The officers of the Associationand the Administration at the Schoolhave done much in promoting theFoundation but their work has beenhandicapped by lack of funds to followup promising leads. Severallarger gifts have been lost because theAlumni Association did not have themoney to send a man from headquartersto present the needs of theSchool. Mines Men at a distance fromGolden cannot keep informed on theurgent needs of the School and theycannot therefore make a successfulappeal for a gift when the opportunitypresents itself. In such cases a manshould be sent from headquarterswho can make an enthusiastic presentationof the claims of the School ofMines for support. The AlumniAssociation needs an executive manager,a full tirae man, with salaryand expenses assured so that he canswing right into this Foundationraising problem. There is no way forthe Association to secure the servicesof such a raan until it is sufficientlyendowed.The steady and consistent growthof the Alumni Association has beendue to the unstinted work of a numberof volunteer workers. They havereceived no financial reward for theirservices. Theirs has been a work oflove which cannot he evaluated indollars and cents. The Associationwill always have to depend upon alarge amount of volunteer work fromits members but it must also have awell paid executive manager. Sucha man could work wonders with thepresent set-up.The Colorado School of Mines hasalso been progressing. The ever increasingnumber of students has puta strain on every facility at its command.Several million dollars areneeded right now, for special purposesnot included in state support. If theSchool is to get the gifts so badlyneeded, the Alumni Association mustfurnish the initiative and the drivingpower to get those gifts.The Alumni Association's incomeis derived solely from dues of members,earnings of its Mines Magazine,and the income frora its "Life MembershipFund". The income fromthese sources is not sufficient to supportthe active progressive programthat the Association has adopted. TheAlumni Association has a perpetualjob to perform and it raust have asubstantial endowraent so it can moresuccessfully cope with the numerousproblems confronting it.WALTMANThere is a large, plainly furnishedoffice in the suite of rooms occupied bythe Franco-Wyoming Oil Company inthe beautiful, modern Edison Buildingin the heart of downtown LosAngeles. In the office is a massive,well ordered desk, and a few chairs.The only decorations on tbe walls areautographed pictures of men—menwho have made "Who's Who".Among them is the only living exprcsidentof the United States, aformer vice-president, the commandinggeneral of tbe American Armiesin France during World War I, andothers equally prominent in the politicaland business life of the nation.These men have autographed thephotographs for their friend who occupiesthe massive desk.Their friend has also been listedin "Who's Who". He has truly wonhis " M " in life by sheer hard workand ability. Mines Men are proudof him because he has never forgottenhis alma mater, despite all his worldlysuccess. He is never too deeply engrossedin his responsibilities to shirkservice to the school, or to lend ahelping hand to fellow Mines Men.In 1938 he established a trust whichprovides an annual award to one ofthe outstanding graduates. He hasrightfully earned a place in "MinesWho's Who". The man at the deskand at the controls of the organizationhe directs is William De Witt Waltman'99.Born in Kendallville, Indiana,February 8, 1875, the son of MartinVan Buren and Catherine Huff (Aller)Waltman. In 1889, the familymoved to Colorado Springs, Colorado,where Mr. Waltman attended theold Liller School. In 1895, at the ageof 20, Mr. Waltman entered the ColoradoSchool of Mines at Golden, fromwhich he graduated in 1899 with anE.M. degree.//£ ENTERED TH£ SCHOOLOF MINBS W AMDWlW AN £M.

In 1905, hereceived an appointment which tookhim to Panama where he spent 2 yearsas superintendent of mining and 3years as superintendent of constructionon the Culehra and Porto Bellodivisions of the Canal. He was a recipientof the Roosevelt PanamaMedal. Impaired health necessitatedhis leaving the Canal area and followinghis return to Colorado in 1910,he accepted the position of Chief Engineerfor the Costilla Estates DevelopmentCompany, then engaged in theconstruction of the Sanchez Dam nearSan Acacio, Colorado.In1911, Mr. Waltman met Mr.P. E. de Caplane who was in Wyoming,representing large French oilinterests in that area. The subsequentdevelopment of that friendshipmarked Mr. Waltman's entranceinto the field of petroleumengineering. Engaged at that timeto head the field engineering work forthe French interests, Mr. Waltmansoon enteredinto tbe administrativedirectorship of the extensiveFrenchholdings in the prolific Wyoming oilfields.Mr. Waltman is now a Directorand Executive Vice President ofFranco-Wyoming Oil Company, theparent organization, and Presidentof that company's several operatingsubsidiary companies, namely: Mc-Elroy Ranch Company, operatingextensive oil and cattle propertiesin West Texas; Franco-WesternOil Company, operating oil propertiesmAAMAf 0£ WITTOF" HIS MAf^V TlTL£SA/O/VE IS AiOF?£/MPO^TAfJT WV M'SEM FROM MMES-.in California; Franco-Central OilCompany, operating oil propertiesthroughout Kansas; and Franco-WyomingSecurities Corporation.

W H A T "MINES" H A S T O OFFERByDR. M. F. COOLBAUGHPresident, Colorado School of MinesSince the legal estahlishment ofthe Colorado School of Mines in 1874,approximately 8,000 men have matriculated.Of this number, in Mayof this J'ear, 2,381 will have receiveddegrees. This fact alone establishesthe premise that Mines has had andstill has something attractive andspecific to offer to the young man.Man is so constituted that he isstrongly favorable to something whichis essentially different. "Mines" isthe one school in America which limitsits field of endeavor to one type ofengineering—^that of the mineral industry.It is devoted exclusively tothe discovery, the recovery, and thetreatment of the minerals of tbe earthand their adaptation to the use of man.The moment that a boy decides on hislife interest, at that moment he beginsto look for the best place in which totrain for that life work. If that interestis in mining, metallurgy, petroleum,geology or geophysics, a thoughtfulinvestigation will direct him tothe Colorado School of Mines becauseof the opportunity for highly specializedtraining.One of the ideas uppermost in themind of a virile young man is, "WhenI finish my training can I get a job?"In 1939 of a class of 133, every graduatebad been offered a job by Septemberfirst.* There is always a job forthe well trained, willing, and reliahleindividual.* Co mme 11 ted on by N. Y. paper last fall.THE Y O U N Gfective results. The major portion ofthree summer vacations is spent infield work where the student learnsto do as well as to think. This workDR. M. F. COOLBAUGHis organized and supervised by facultymen, who are not only thoroly trainedacademically, but who are recognizedby industry as men who are superiorin their fields. This type of trainingis definitely an asset when the studentbegins to look for a job.This training at Mines consists ofthe basic fundamentals of engineeringtogether with a practical applicationin the field which gives especially ef-The Colorado School of Mines iscomparatively a small school. Thisoffers a distinct advantage in personalcontact with the faculty and in acloser association of students. Freshmenare counseled and taught hy professorswho are heads of departments.There is an opportunity for exchangeof experiences between students fromM A Nall parts of the world. They freelydiscuss world economic conditions,forms of government, trade relations,and problems of labor. The studentfrom Australia discusses the miningmethods in his country as comparedwith those of America. The Venezuelangives of his knowledge of the oilfields in exchange for that of the manfrom Persia or Turkey who is alsointerested in this field. Students fromChina and Japan and the Philippinesadd their contributions to tbis fundof worldwide experiences. All thisgives the student a wealth of knowledgeand an enlarged vision which isinvaluable.There are three factors vitally essentialto the life, growth, and perpetuationof an educational institution—the faculty, students, and thealumni. Each student of the ColoradoSchool of Mines, upon becominga graduate, automatically inherits analumni organization which is activethruout the world. This group ofMines men has already paved the wayfor every new graduate from theschool by establishing for him a reputationin advance. The recent graduatemust live up to this already acquireddistinction and in addition must rendera service necessary to uphold this renown.While the Colorado School ofMines has much in general to offertbe prospective student, yet specifically,the most important factors are:the highly specialized training in themineral industries; the feeling of securityin receiving a job; the attainmentof a basic engineering trainingplus an opportunity for practical application;an ideal relationship of studentsand facult)' and of students withstudents; and lastly, a well organizedand functioning alumni association.164 THE MINES MAGAZINE * APRIL 1940ByJ. HARLAN JOHNSON, '23Associa+e Professor of Geology andCurator of the MuseumCoiorado School of MinesMines alumni and friends will bedelighted to know that the School hasreceived tbe famous Hoffman miningmurals which were painted for themining exhibit at the Golden Gate InnationalExposition of 1939. Theywere displayed in the Hall of Mineralsleading to the mining exhibit of TreasureMountain.The Artist*Born in Boston in 1901, Irwin D.Hoffman received bis training at theschool of tbe Museum of Fine Artsin that city. In 1924 he was awardedthe Page Traveling Scholarship, andfor the following two and a half yearstraveled and studied in various partsof Europe. Returning to this countryin 1927, he took a studio in New YorkCity, where at intervals he has exhibited.His interest in mining arose fromthe fact that both his brothers are miningengineers. With them he visitedmost of the mining camps in tbeUnited States and Canada, and severalin Mexico.Shortly after the discovery of thefamous Noranda mine in Quebec in1922, he spent the summer of 1924prospecting in this area and participatedin an old-timers' gold rush withplenty of excitement but not much*The statement about the artist an& the detaileddescriptions of the nuirals are taken' with very littleor no change from the well written article •MiningExhibits, Inc. secures the Hoffman Murals" publishedin the Western Mining News, February, 1939.The cuts used were courteously loaned to the MinesMagazine by the Western Mining News, through theefforts of Frank Hayward, President of the Bay CitiesSection.-cotnTHE MINES MAGAZINE ^ APRIL 1940I .gold. However, the experience formedthe background of an interest whichhas been increasing with the years untiltoday his etchings, paintings andmurals of mining activities and menare winning for him sure and substantialrecognition.Unlike others who have attemptedmining subjects, Hoffman's work inaddition to an outstanding virility andartistry, is authentic in all its technicalmining aspects. His work soon cameto the attention of mining men, andas a direct result he was invited tobecome a member of the American Instituteof Mining and MetallurgicalEngineers in 1936. The secretary ofthe organization wrote as follows:"According to the published recordsof your training and position, you havethe qualifications for membership, andI herewith extend to you an invitationto apply."The MuralsThe murals are six in number andshow vividly various stages in the historyof mining.Panel IThis panel depicts the three earlystages in the development of mining{Fig. 1). In the upper left corner wesee a group of Piltdown miners workingstopes for flint. As far as we know,this is the earliest recorded miningoperation in tbe history of man (about50,000 to 125,000 years ago). AtObourg, in Belgium, a series of prehistoricunderground flint workingshave been discovered. These have beenfreely described by T. A. Rickard inhis notable work "Man and Metals".Their tools may he seen in the RoyalMuseum of Natural History in Brussels,Belgium.In the upper right section is shownthe beginning of the Iron Age. TheCave Man discovers that meteoriciron can be recovered and fabricatedinto implements by heating and forging.This was his only source of metalfor the thousands of years that precededthe discovery of copper and tin.In the lower half of the panel isshown the first smelting and castingoperations of primitive man and wefind ourselves in the Bronze Age. Thisperiod coincides with the last periodsof glaciation some 20,000 3'ears ago.The Cro-Magnon man representedhere was our real progenitor and resemblesus closely. He was about sixfeet tall and had a brain capacity fullyas great as ours. In the building ofhis fires he discovered that some of thestones with which he built his hearthwould melt and then congeal into aspongy substance that could be fashionedinto implements of variousshapes by pounding. His natural intelligencesoon led him to the discoverythat this substance, copper, could bemelted in a specially constructed furnaceand poured into moulds whichwere cut into stone, and in this wayhe discovered the principles of casting.Thus we see in the center of this panelthe primitive smelter, pumped to asmelting heat by the man with theblow torch and his companion pressingon primitive bellows which wereprobably made of the hides of animals.In the left foreground, is a sword beingtaken from the case, and hatchetsand spearheads are being poured. Theman in the lower right foregroundpounds his sword on an anvil to temperit to proper strength. Directly behindhim, we see the potter's wheel whichwas also developed by primitive manat about this time. Eventually belearned to use his potter's skill to constructmoulds for casting.165

Panel 2i 5This panel (Fig. 2) is devoted tothe mining and metallurgical operationsof the Egyptians. There havebeen excellent descriptions of Egyptianmining methods left to us in bas reliefsand hieroglj'pbic accounts. Men,women and children slaves performedall the labor necessary to extract, reduceand refine the ore. The fullestdescription of Egyptian mining, however,is given us by an ancient Greek,one Agatharchides, who visited Egyptin 50 B. C. He says in part:"for the Kings of Egypt collectcondemned prisoners, prisoners of warand others, who, beset by false accusations,have been . . . thrown intoprison; these sometimes with their entirefamily, they send to the goldmines. . . . Those who have been thusconsigned are many, and all are fettered; they are held constantly at workby day and the whole night long withoutany rest and they are sedulouslykept from any chance of escape. Thehardest of the earth that contains thegold is exposed to a fierce fire, so thatit cracks and then they apply handlabor to it. . . . Of those who arecondemned to this disastrous life suchas excel in strength of body pound theshining rock with iron hammers . . .and they drive galleries ... in the directiontaken naturally by the glisteningstone; these then, on account ofthe windings of these passages, live,in darkness, and carry around lampsattached to their foreheads . . . andthis they do without ceasing to complywith the cruelty and blows of tbe overseer.The young children make theirway through the galleries and throwup with great toil tbe fragments ofbroken stone and bring it to the groundoutside the entrance. . . . There is noforgiveness or relaxation at all for thesick, or the maimed, or the old, or forwomen's weakness, hut all with blowsare compelled to stick to their laboruntil worn out they die in their servitude."Thus we see in the upper left ofthe mural tbe miners crawling throughtheir galleries, pushing the ore out;the ore being passed by means of anendless human chain; the minersbeaten as they work by their guards;the treadmill, showing their onlymeans of power. In the middle backgroundis shown tbe human stampmill, men crushing the ore with ironpestles, which process is repeated bythe women and children until the oreis crushed to powder. Then it iswashed on the wash table (lower leftcorner )and brought to the smelteroperated by two slaves working footbellows (lower right). The bellowswere made of pigskin and the smelterof fashioned brick. The matte (thesmelted ore) is then put into the crucibleimmediately behind the smelter,where it is further refined by the processof tbe blow-torch. Directly behindthe crucible we see the pouring of theunrefined gold into earthenware pots.The craftsmen mix into this a proportionatelump of lead, grains of salt,and a little barley bran (forming acarbon) and then the mixture is putinto an oven. The gold emerges purified.Panel 3This panel is devoted to the miningmethods used by the ancient Creeksand Romans (Fig. 3), which werefollowed for centuries until the useof gun powder. In the right section isshown the operation of fire-setting. Afire was kindled against the face of therock until it reached a certain intensitj';then the rock was well dousedwith water by a bucket brigade, causingthe rock to contract and crack.After this it was pried loose by theminers and pounded into small enoughfragments to be carried out of themine. In tbe left section we see theuses to whicb the Greeks put theirprecious metals. A bronze statue isbeing cast (probably in the studio ofPhidias) and further back we see aperfect example of bronze casting(copper and tin). In the backgroundis the Acropolis, crowned by theParthenon. All this was made possibleby the treasure which the Athen-ians derived from their silver minesat Laurium.In his book, T. A. Rickard recountsthat during the wars whichthe Athenians fought, the enemywould attack the valuable silver minesat Laurium. The miners would invariablydesert to the enemy becauseof the excessive cruelty of their masters.Then Athens would go into asharp decline until the mines wererecaptured from the enemy and putback into working order. Thus theeconomy and social order of Greecewas directly influenced by their miningindustry.Panel 4Surface mining is here indicated(Fig. 4) in its various phases, fromthe two forty-niners panning nuggetsfrom the stream to "rocking" in thelower left hand corner, hydraulickingand finally dredging.Hydraulic mining and dredgingwhich originated in California, survivedfrom the early days of placermining with dredging rapidly replacinghydraulicking. We see a bulldozer below the dredge clearing theground of vegetation and debris preparatoryto the oncoming of thedredge. Again is illustrated the ingenuityof man.While the basic elements of placermining are retained in the dredge, tbemodern monster is capable of treatingmillions of yards of gravel of lowgrade material which in the old dayswere beyond the power or knowledgeof the pioneers to exploit.In the upper right hand corner isdepicted an open cut mine which shovelsthe ore and waste in huge quantities,the ore being conveyed by a railroad,the track being laid in a seriesof benches. No project is too large orcomplicated in its operations for themodern miner who is becoming moreand more expert in extracting thetreasure of the earth.Panel 5This is devoted to modern miningand reducing operations (Fig. 5).While the basic principles of miningand smelting of the ancients have endured,the various processes have beengreatly developed and amplified. Mininghighlights the story of man's emancipationfrom backbreaking labor byhis development of horse power. Withthe coming of power, machinery andchemicals, the old laborious handmethods have been replaced forever.We see men in the left foregrounddrilling into a rock face. Two menare loading drill holes preparatory toblasting. In the center is illustratedthe method by which broken ore isdrawn from the stopes thru ore chutesand loaded onto cars driven by motors.The ore is conveyed to the shaft ortunnel adit ready for crushing andtreatment. A conveyor belt in fheright middle foreground shows howthe ore is taken to a reducing plantor mill where it is crushed and finelyground by means of a power-drivenball mill.The next process is the extraction ofmetallics from the ore by flotation orgravity methods, cyaniding, if necessary,to remove the gold, after whichfollows the final stage of smelting andrefining concentrates in the huge furnace(shown in the upper right handcorner.)Panel 6This panel (Fig. 6) sums up thestory of man and metals. The mineris holding a piece of ore in his hand,surrounded by all that this has madepossible, such as the modern city, theocean liner, the stream-lined train, tbeautomobile, power, industry. Themovie industry depends on silver andthe radio would be impossible withoutcopper. Around the microphone arelips suggesting some of the many andvaried voices which make up the radioprograms of today. Overhead is seenan ultra-modern airplane, and ironicallyenough, in the lower left handcorner is an anti-aircraft battery mannedby a crew protected by gas masks.The panel suggests the might of(Continued on page 170)THE MINES MAGAZINE APRIL 1940THE MINES MAGAZINE ^ APRIL 1940167

COLORADO SCHOOL OF MINESByJ.

H.Buell and Company, Architects, whoplanned the rest of the Geologj'-Geophysicsbuilding. Plans and specificationswere first advertised on January31, 1939, and the bids were openedon February 21. The Mead andMount Construction Company, whichhad erected tbe central unit of thebuilding, was awarded the contracton a bid of $144,000 to constructboth the Museum and Geophysicswings. The total cost of the build-1 Mines Magazine, vol. 2S, pp. 121, 219. 330,377, 461."Mines Magazine, vol. 29, pp. 272-273, June,1939.NEW GEOLOGICAL MUSEUMing and wings with equipment was$454,000. Tbe Museum Wing wasnot turned over to tbe school untilthe middle of January, 1940, whilethe Geology Department did notcommence moving into it until aboutFebruary 1.J. HARLAN JOHNSONGeneral Floor Plans of theMuseum WingThe wing measures approximately62 X 115 feet and contains a basementand main floor. Tbe floor plans areshown by Figures 3 and 4. The longside of the wing is oriented in an approximatenorth-south direction withthe west side facing Maple Street(Fig. 2). A west entrance fromMaple Street opens on the main floorand the main exhibition room of themuseum. Figure 3 shows thearrangement of the ground floor orbasement. This is on a level with theground floor of the Geology buildingand of the Geophysics Wing. No. 1represents the hallway entrance intothe main building; No. 2 is the stairwayto the main floor; No. 3 is alarge room intended to be used laterfor the exhibits; No. 4 will house tbereference collection of fossils. No. 5the reference collection of minerals.No. 6 is the shipping and receivingroom, while Nos. 7 and 8 are storerooms and 9 and 10 rest rooms.The main floor, as shown in Figure4, contains the main exhibitionhall (11) and two small store rooms(12 and 13). No. 14 represents theentrance opening on Maple Street,and No. 15 the hall and doorwayleading into the main Geology Building.All the rooms are well illuminatedby natural or artificial light. In themain exhibition hall the new fluorescentlighting bas been used with verypleasing effect.CuratorDr. J. Harlan Johnson has beenappointed curator of the museum inaddition to his other duties as AssociateProfessor of Geology. He willbe assisted by the other members oftbe Geology Department in preparingthe exhibition collections and will beadvised by the heads of the degreegrantingdepartments relative to themost efficient use of the museum foreducational purposes.Functions of a MuseumThe desired functions of the museumare visualized to be those listedbelow:1. To collect material.2. To exhibit material.3. To build up research collectionsand stimulate research.4. To actively assist in the teachingwork of the school (a) by havingexhibits to illustrate subjects taught,(b) by having reference research collections,and (c) by the personal activitiesof the curator in supervisingresearch and graduate work based onmaterial in the museum collections.5. To publish and otherwise disseminateinformation to the public.In time, the School of Mines Museumhopes to serve the institution byaccomplishing all of these functions.ExhibitsIn the museum there will be hothexhibition and non-exhibition collections.In planning the exhibits, itmust be remembered tbat the ColoradoSchool of Mines is a mineralindustry school and that geology isthe basic science in mineral industrysince it deals with tbe origin,occurrence, and discovery of mineralsupplies. Three ideas are being keptin mind in preparing the exhibits:(1) To present material to illustratecourses taught in the school, especiallymineralogy, economic geology,petrology, historical geology, andpaleontology. (2) To supply plentyof charts, diagrams and explanatorytexts with the exhibits and to wordthem so as tO' be easily understood,and to make tbe collections as inter-' 'St- jj jj niifl l i l l l l•V Fig. 2.esting as possible to tbe layman andvisitor as well as to the students soas to stimulate popular interest. (3)To illustrate and emphasize associationsand economic importance andapplications.Non-Exhibition ResearchCollections• Fig. 5. Center and table specimen cases.These are collections for the use ofadvanced students, specialists, andothers. They are not to be on exhibition,but to be kept in drawer casesin special rooms (Fig. 3, Nos. 4 and5) where they may be studied. Thesecollections include:(a) The type mineral collection.A systematic collection showingsamples of each mineral and variety,from every locality from which wecan obtain specimens.(b) Paleontologicai collections.Under this heading are collections offossils from Colorado and adjoiningstates arranged by formation andperiod, and collections of identified\ \ \ 1 •Museum from the southwest."Imaterial from other areas for comparativestudies.(c) Ores and non-metallics of economicimportance from producing districtsand areas.(d) Specimens illustrating unusualgeological features. In time thesenon-exhibition research collectionsshould assume an importance as greator greater than the exhibited collectionsfrom an educational viewpoint,especially if the School of Mines developsas a graduate school.EquipmentNew museum cases to equip approximatelyhalf of tbe main exhibitionroom were obtained with thebuilding. These were built by theFig. 4.._- 0• aFIRST FLOOa PLAMa11- \Remington-Rand Company and areof modern design and of the best constructionobtainable. They include7 table cases 8 feet long x 4 feet wide,(Fig. 5) 2 wall cases 10 feet long,(Fig. 6) and 8 tall center cases 10feet long.

oak bases. They are similar in typeto those used for the mineral exhibitat the American Museum of NaturalHistory in New York City. Thesewill occupy the south half of the halland will contain the exhibits of minerals,ores, and rocks.Old furniture inherited fromGuggenheim Hall will be used in thenorth half of the main exhibitionroom until new cases to match theothers can be obtained. These willcontain the exhibits illustrating invertebratefossils, historical geology,and the non-metallic economicproducts.The basement rooms 4 and 5 areequipped with tall drawer cases tocontain tbe reference collections ofminerals and fossils.Specimens Available forthe CoilectlonsThe school has a large amount ofmaterial available, especially mineralspecimens. Much of the material becauseof lack of space has been packedin boxes and barrels and stowed awayin basements and attics for years. Nosingle person has as yet ever seen allthe collections as some boxes werepacked away before any members ofthe present faculty joined the Geology• Fig. 6. Wall case for mining districf exhibits.Department. At present, the materialis being unpacked and manyinteresting things are coming to light.It is expected that the unpacking willbe completed during April, and exhibitswill be feady to display to thepublic by Commencement Day (May24, 1940) though it will probably beseveral years before tbe collectionswill even approximately attain thestandard and character ultimately desired.However, by HomecomingDay next Fall, the cases will be filledwith worthwhile exhibits having considerablecolor and interest.Materials NeededThe collections lack many neededand desired items especially rare andnot spectacular minerals for thereference mineral collection, and fossils,ores, and economic non-metallicsas well as showy specimens. As soonas the Geology Department has unpackedthe material available androughly assembled tentative exhibits,it is planned to publish in the MinesMagazine lists of specimens neededfor the collections in the hope thatalumni and other friends of the schoolmay be able to help build up a museumwith collections that will be avaluable and outstanding educationalfeature of the Colorado School ofMines.^uraid—(Continued from page 167)man's achievement through tbe ages,with mining the key which has openedup this treasure vault. There is alsoa suggestion that civilization hasreached the crossroads. Will the processesof development and constructionoutstrip the forces of destruction?How Mines Obtained ThemEarly in the summer of 1939, Mr.Irwin Hoffman visited the ColoradoSchool of Mines in Golden and at thattime suggested that the School shouldendeavor to secure the murals at theconclusion of the Golden Gate InternationalExposition. It was suggestedthat the murals would be anexcellent decoration for the new GeologyMuseum then being constructed.This suggestion appears to have beenthe starting point of efforts to obtaintbe murals for Mines.

'05Consulting Mining EngineerDenver, ColoradoAt tbis time of the year, manyyoung men in our high schools arebrought face to face with the choiceof a career and the college for perfectingthe decision. For several yearsthe student has known that he mustdecide, ultimately whether he is tobe an engineer, or seek advancementin the law, medicine or some otherprofession. We cannot always runaway from weakness, sometimes wemust fight or perish, and if that beso, why not know, where we stand?To choose a profession is the sameas announcing that one seeks thebenefits of a higher education. Aneducation must be defined. If wecan visualize life as a pathway reachingfrom the infinity of the past tothe infinity of the future:—If thepower be granted to us to scan thispathway we will see that most of it liesin drab shadow, occasionally brokenby some brilliant flare that representssome extraordinary advance in thewelfare of the human race. An observeris impressed by the great emptinessof this pathway. It is deserted,for the men who stand upon it havetime only to know that they are a partof life, when they must make way forothers. In a cloud of dust spreadover the plain beneath us we seeaction. In the cloud and beneath itwe see children born, youth develop,and surging forward, seize the torchesof human knowledge and wisdom fromthe uplifted hands of their elders, whobeing weak, falter, and fall by theway side.Tbe wisdom of the race isFRED C.4CARSTARPHENlocked in our libraries. The impartingof it is intrusted to our teachers,but its accomplishment is the rewardof individual effort. The strange partof life in its general aspect, is its organization,A generation of men inpower, the aged, passing, and j'outhcoming on. Three generations dovelocked,exemplify tbe living representativesof humanity, and are thecustodians of its ideals, its aims, itshopes and ambitions. If human effortis directed toward some goal, it isimperative that each generation attainas complete a knowledge of the experiencesof previous generations aspossible. It is necessary not only toknow the history of mankind, but toponder upon past experiences to planthe next advance toward the goal oftruth and perfection.Our forefathers believed in theeducation of youth so strongly thatit was a social obsession. Nine collegeswere endowed privately, beforetbe American Revolution. Thephilosophy of today advocates the expenditureof national savings upon theaged to the neglect of youth and educationalprograms. It remains to heseen whether our educational systemsbrought forth this Frankenstein orwhether the ideals of past generationswill prevail. This brings the differencehetween civilization and cultureto our attention.Hardly three generations havepassed since our great grandfatherswere settling New York State. Then,there was nowhere in the world, arailroad, or a telephone, or a telegraph.There were no refrigerators,no plumbing, no sewing machines.There were no matches to light fireswith, or coal ranges to light them in.For three generations we have beengiving our attention to the buildingof a vast complex of implements, bymeans of which to live. Possibly wehave been contemptuous of ideas, hutamorous of devices. Now mankindstands with its hands filled with devices,hut less sure and more bewilderedabout its destiny than everbefore.Back in the 19th century, weAmericans were optimistic. Progresswas our real religion. We livedin the time of perfection of tbe mostastonishing devices, and life becamean eager standing on tiptoe, wonderingwhat new marvel would arrivebefore night fall. We thought we weresuccessfully headed toward our placein the sun as a great nation. Wehave brought forth a marvelous civilization,rapid communication, speedytransportation, and millions of implements,and the question grows insistent:—-To what end will mankinduse them? The answer is to he foundnot in our civilization, not in our massaggregates, but in our culture. Thisis the realm of our individual contributionsto spiritual ends, as expressedin our art, literature, moralsand religion, for which at best we live.As young men you are interested inyour material advancement and inseeking a place in the materialism oflife do not overlook the importanceof thought and culture.Mr. Gerard Swope, retiring Presidentof the General Electric companyremarked a year or so ago that "inthe United States over a period oftime and particularly recently, wehave made rapid changes in the reductionof the work week, and increasedrates of pay, which industry has beenenabled to absorb thru the simplificationof designs, better methods andgreater mechanization of industry,170 THE MINES MAGAZINE * APRIL 1 940THE MINES MAGAZINE * APRIL 1940 171

and the ingenuity of management. Asan example of our progress, in theshort space of my own active lifethere have been great changes. WhenI started work in 1895 our work weekwas 56 hours at 12^^ per hour, or$7 per week. Today a young man ofabout the same grade would work 40hours (25% less) and receive 70^5per hour or nearly six times as much".He pointed to the fact that thesechanges have not ruined AmericanLabor or Industry for they were advanceswithin the fabric of society andnot the result of political and racketeeragitation. The following table givesthe comparative amount of labor thatthe average European workman of1938 had to expend to obtain theessentials of living as compared witha workman in tbe United States.EuropeAv. 8 UnitedCountries StatesNumber of months workto pay a year's rent.... 2.8 2.2Number of hours workto purchase a unit offive foods 5.7 1.7Number of months workto purchase an auEomobiie- - 16.3 +.5Number of months workto purchase an electricrefrigerator ___ 3.7 1.0Number of months workto purchase a radio set 0.8 0.2Number of minutes workto purchase 1 kilowatthour of energy.- 24 3.6Number of hours workto purchase on incandescentlamp 2.0 0.2These facts illustrate tbe superiorstandard of wages and living achievedby American Industry, labor andengineering, through inteUigent cooperationand understanding. Therecord would he better if this brainwork and understanding functionedcontinuously without interruption byparlour pinks and racketeering demagogues.The record is sufficiently impressivethat we may continue to havefaith in the future.As a high school graduate you facelife with reasonable chances of attainingsuccess. In fact these chanceshave been estimated by a carefulscrutiny of statistics that center in theoffices of our large insurance companies.Some of the important deductionsare as follows.You have an even chance to live tobe 69. During the last 100 years theaverage span of life has increased 20years. It is expected to increase morethan this figure. Of all the childrenhorn this year, 75% will he ahve atthe age of 50, 25% at the age of 78.Your chances of getting a job, arebetter than 4 out of 5, and as anaverage young man you have a 50-50chance of attaining an income adequateto a fairly high standard ofliving, namely $2,000 per year.The chances are 9-10 that j'ou willmarry, and within 5 years, but youmay not marry your present sweetheart,because the average man marriesat 25, and the young woman at22. Since j'our present girl is 20she may not wait for you. Thechances are always against a manmarrying a girl of his own age orolder. After you are married, thechances of escaping divorce are 4 outof 5, although the rate is rapidly rising,your protection is children. Youwill have half as many children asthe average father of the past generation.He had 6 you may have 3.You will die sooner if you do notget married. The home environmentis more healthy. If you marryhappily at 25, with a wife of 22, youwill have 3 chances in 4 of celebratingyour silver wedding anniversary.These chances in life of a highschool graduate may not satisfy you.Ambition surges within your manlychest, and you scrutinize the recordsof the college graduates. We do nothave the space to discuss the recordsof all types of educated men, but thefollowing data about engineers are ofinterest. It is understood that theengineering graduates, were first highschool graduates and therefore haveadded chances of success beyond thatof the high school graduate.A recent survey disclosed that outof 54,000 officers of some 500 typicalindustries studied, the college man is7 times more likely to be an officialthan the non-college man, and theengineering graduate is 30 times morelikely to be an officer than thegraduate of a non-engineering college.The advantage of the engineeringgraduate over the non-engineeringgraduate applies to all positions.He has 12 times the chanceof becoming president, 5 times thechance to be treasurer, 30 times thechance to hold positions in production,174 times the chance in engineering,and 24 times the chance insales. The engineer bridges the gapbetween science and the public, andhis responsibility is the developmentof tbe applications of science in such amanner that they may fit beneficiallyinto the existing social order.High school graduates are turningto higher education, and engineeringcolleges are not being neglected. Forinstance in the year 1936-37 therewere 70,030 engineering students in118 of the 150 engineering schools inthe United States. In 1938-39 therewere 87,760 students in 119 schools.This is an increase of 25% in twoyears, for all engineers compared witha 34% for the mineral technologygroup. In this latter group in 1938-39, 9,619 students were resident in53 mining schools in the UnitedStates; and Canada, contributes1,014 students in her 6 schools.This is the largest enrollment everrecorded, and represents a gain of34% over ^1936-37 and 117% over1932-33. This enrollment compareswith that of other major engineeringundergraduate groups in the UnitedStates and Canada, as follows for1939. Mechanical engineering,20,004, electrical 13,135, chemical12,438, civil 10,585, whereas we repeatthat the mineral technologiststotal 10,633.Of the 9,619 mineral technologystudents in the United States 37%are taking courses in petroleum andnatural gas, 25% in metallurgy, 20%in mining, 8.8% in geology, 8.6%in ceramics, in fuel technology,and 1% were special students.The reports on the employmentstatus of the 1938 mineral graduatesshow that out of 951 men whograduated, 668 are filling positions inthe mineral industry, 105 are employedin other fields of work, and110 are attending graduate schools.It is quite apparent that the nextfew years will see a great increase inthe number of mining engineers, andthecapabilities of the leaders of theprofession will be greatly enhancedby the competition of these manymen. However the fieid of mining iscalling for real mining engineers, ascompared with other days when miningwas considered to be an easy profession.Mining engineers are confrontedwith the problem of makingall minerals and metals, and productsused in industry easily accessible tothe place of need. Hitherto fnAmerican Mining we have evadedreal technical difficulties by turningto the rich deposits that were accessibleand easily worked. Such oreoccurrences are becoming rare. Oursurface deposits are practically exhausted,in common with the petroleumengineer, the miners are workingat greater depths than ever beforeto recover ores of such low gradethat they were beneath notice a generationago.It was common to listen to engineeringgraduates criticise the curriculumand vehemently declare thatthey never found any use for the subjectsthey studied. This has changed.Most practicing engineers feel thatthey did not cover enough ground,and they are bestirring themselves tokeep abreast of the advances that havebeen made recently on all educationalfronts. The mining industry is demandingbetter methods of locatingore bodies, reaching, transporting,and processing them.The petroleum engineers havetaken the lead in the discovery of oil,(Continued on page 202)WHAT IS A MINERAL ECONOMIST?An answer with a brief discussion and definitionByHARRY J. WOLF, '03Mining EngineerNew York CifyFrom the time the profession ofengineering began to evolve convenientand appropriate subdivisionscorresponding to its definitely specializedbranches, such descriptive professionaltitles as Civil Engineer, MechanicalEngineer, Mining Engineer,Metallurgical Engineer, ElectricalEngineer, and the more general or inclusivedesignation of ConsultingEngineer, have been in common useand their meanings are well understood.However, during the pastfew decades a tendency has developedin various lines of commercial activityto augment the dignity, oremphasize and exaggerate the importanceof the individual, by designatinghis occupation as some form of "engineering",and by inventing new titlesthrough the simple process of placinga modifying and descriptive adjectivebefore the word "engineer". Thispropensity was for a time carried tosuch lengths that many of the newlymanufactured titles or designationswere more humorous than dignifiedand were eventually regarded as absurdities,became confusing, and weregradually abandoned.In similar manner the term "Economist"for a time began to acquiremodifjdng and loosly descriptive adjectives.Some of these new designationswere practical and informativeand have become useful. However,when the multiplicity of new titles ofthis species began to include almostevery commentator or writer whoassumed the duty of expressing anopinion or producing a paragraphcontaining the merest reference tomoney matters or prices of securitiesor commodities, and having little ornothing to do with the actual scienceof economics, it is little wonder thatthe average reader became confusedand began to ask for definitions.During a recent casual discussion ofthe present high degree of specializationin professional and technicalwork, attention was called to the factthat tbe activities of certain large industrialorganizations, which had adefinite interest in the economic andcommercial aspects of various mineralsand mineral products essentialto their operations, had led to thegradual creation of a new and specializedprofession which was referred toas that of "Mineral Economist". Theindividual so designated is usually amember of the technical staff of thecorporation, and his duties often combinethose of a statistician and factfinder, an expert buyer, an exaltedstock clerk, and a departmental consultingengineer.^—- _ - —HARRY J. WOLFAbout a year ago specific recognitionwas accorded this profession ordesignation by the General LandOffice, Department of the Interior,when the United States Civil ServiceCommission announced open competitiveexaminations for tbe positionsof "Senior Mineral Economist","Mineral Economist", "AssociateMineral Economist", and "AssistantMineral Economist". Then someoneasked the question, "What is a MineralEconomist?" A general answerto the effect that "a Mineral Economistis a person well versed in thecommercial and economic aspects ofminerals" might be all right for anabridged dictionary, but it is not ascomprehensive a definition as the titledeserves, especially if it refers to anexpert who is to be nominated as apublic servant In a department of theUnited States Government. Withthis idea in mind, the following definitionand specifications are submitted.A Mineral EconomistA Mineral Economist is one whohas at his command an extensive fundof both general and detailed informationregarding metals and minerals,and has the ability to impart such informationto others who are entitledto receive it and desire to use it forscientific or commercial purposes. Heis an active member of a highlyspecialized profession, with a scientificbackground, a distinct flare for research,a thorough understanding ofstatistics, a clear conception of economics,and a wide acquaintance withthe laws of supply and demand asapplied to the substances and productswhich are the basis of his investigations.In order to render efficient servicein the fieid of Mineral Economy, theeconomist must have available forready reference all known facts regardingevery identified metal or mineral.This basic fund includesknowledge of the following:1. Geological conditions underwhich each mineral occurs, or whichfavor its occurrence. (Here is wherethe Colorado Mines raan is thankfulfor his thorough courses in geoiogyand lithology).2. Mineralogy in detail, includingability to identify important mineralsand to discriminate with regard toquality and commercial utility. (Hereis where a Coiorado Mines man maybring Into play his field training, hispast association with one of the finestmineral tj^pe collections in the world,his unique instruction in crystallography,and his vacation experiencesin mines or on geological field trips).3. Physical, chemical, and otherproperties of all important minerals.(In this connection a Colorado Minesman would have a chance to apply hispractical experience in ore dressing,and his observations in the petrographiclaboratory, including his studyof mineral sections under the microscope).4. All known occurrences, classifiedby countries, states, counties, districts,and individual deposits of specialprominence.5. Quantity and quality available.This involves a comprehensive understandingof the essential characteristicsand uses of minerals that arediscussed in terms of tons, pounds,ounces, milligrams, or carats; and172 THE MINES MAGAZINE + APRIL 1940TKE MINES MAGAZINE APRIL 1940 173

whose uses vary from blast furnaceflux to delicate optical instruments.6. Cost of production. Considerationof this point would naturallybring up a comparison of relative costsat various mines, and in widely distantlocalities with their variations inquality of labor, availability of consumablesupplies, transportation facilities,and local political influences,regulations and restrictions.7. Market price of crude materialor refined products. This implies awide acquaintance with trade conditions,market practices, customs, andcharacteristic procedure in conductingnegotiations and making contracts.8. Known commercial uses andadvantages. Many common mineralshave widespread and diversified uses,some of which are appreciated onlyafter technical inquiry and personalcontact. For example, consider thegreat variety of industrial uses of suchminerals as sulphur and calcite. Newuses for minerals are discovered anddeveloped from month to month, andthe engineer who would keep abreastof progress in this respect must maintaincontact with important research,available indices of technical literature,and reviews of patents.9. Processes employed in preparation,treatment or refinement. Thisimplies keeping abreast of latest practicein metallurgy and ore dressing inso far as they may have a bearing onthe subject of mineral technology andthe preparation of minerals for themarket.10. Results of latest known research.At least a casual contact withthe more prominent developments inthe realm of pure science may bebeneficial when least expected, owingto the fact that important discoveriesdestined to influence future uses andmarkets are sometimes closely relatedto the mechanical, optical, chemical,or radio active quality or characteristicof some mineral.In order to conduct efficient researchand properly accumulate, coordinateand make available forready reference the most serviceableinformation, the economist must investigateand classify the users of suchinformation, or the consumers of theminerals. In this connection it isnecessary to accumulate and classifythe following:1. The names of those who mayuse the information either for academicpurposes or serious scientificresearch:(a) United States GovernmentDepartments or Agencies.(b) Departments of foreign governments.(c) Domestic manufacturers or researchorganizations.(d) Educational institutions.(e) Libraries,(f) Individual investigators.2. The names of users or consumersof metals, minerals or products:(a) United States Government{Army, Navy, and other departmentsand agencies).{b) Domestic manufacturers andconsumers.{c) Foreign governments.(d) Foreign manufacturers andconsumers.Referring especially to items (c)and (d), it should he noted that considerabletact, prudence, or specialregulation or restriction may be desirablein the discussion or transmissionof information of this characterwith respect to foreign governments,manufacturers or agencies.It is possible that the problemsfaced by a Mineral Economist may beso numerous and extensive that adequateresults can be accomplished onlythrough tbe aid of a staif of ableassistants and correspondents. Thisimplies that the head of the departmentor organization must have executiveability, and good judgmentin the selection of bis assistants; alsothe faculty of developing esprit decorps among his associates and subordinates.All of this means that thestaff of a Mineral Economist shouldhave the following qualities andcharacteristics:1. Resourceful in the accumulationof data. It should be able to prepareefficient and comprehensive questionnaires,and inspire unselfish co-operationamong a wide list of former contactsand professional associates.2. It should be equipped to handlevoluminous correspondence efficiently,and with discretion.3. It should be competent to conductresearch in all available literaturerelating to its work, either inEnglish or foreign languages.4. Its personnel should includethose competent to conduct fieid investigationswhen necessarj', prepareand edit monographs, bulletins, circularsof information, and confidentialreports.5. It should develop and maintaina spirit of cordial co-operation withthe United States Geological Survey,tbe United States Bureau of Mines,and other government agencies.6. It should be equipped to rendervaluable service to citizens entitled toit, and ali government departmentsand agencies in a position to demandit.7. It should serve not only as asupplier of available data which isthe result of its research, but also asan agency that actually inspires newresearch along lines that may havebeen overlooked or neglected.8. The very strategic position ofthe Mineral Economist might enablebim to convert his organization attimes into a veritable nursery of newand novel ideas and discoveries, or atleast offer suggestions or problems forresearch which could be passed on toindustrial leaders or technicians, orinstitutions of learning.In the light of present world developments,the Mineral Economistshould give special consideration tostrategic and essential minerals neededby the United States Government inthe event of war, or to improve itsbargaining position with othercountries. He should study deficienciesand ail means of correcting thera.For exaraple: Antimony, Asbestos,Bauxite, Bismuth, Chromium, Cobalt,Columbium, Cryolite, Diamonds,Graphite, Helium, Iodine, Manganese,Mercury, Mica, Nickel,Platinum, Radium, Tantalum, Tin,Titanium, Tungsten, Uranium,Vanadium, Zirconium; and sourcesand methods of recovery of variousrare elements sucb as Indium andGailium.In addition to cordial co-operationwith the Geological Survey and Bureauof Mines, the Mineral Economistshould maintain contact with suchorganizations as the Mining andMetallurgical Society of America,American Institute of Mining andMetallurgical Engineers, AmericanInstitute of Electrical Engineers,American Society of Civil Engineers,American Society of MechanicalEngineers, American Association forthe Advancement of Science, AmericanElectrochemical Society, theTechnical Press (including the MinesMagazine), leading research organizations,and press clipping bureaus.The working equipment of tlieMineral Economist would no doubtinclude an unabridged card index of:1. Metals and Minerals.2. Individual correspondents.3. Localities and their outstandingminerals.4. Producers of minerals and ores.5. Vendors of minerals and mineralproducts, and data regardingtheir sources of supply, and theirtonnage resources.6. Agents engaged in the mineraltrade, and data regarding their principals.7. Promoters of mining, metallurgicaland industrial enterpriseswhich may have special significanceregarding the technique of the industry.8. Consumers of minerals andores, with data relating to tonnagerequirements, customary ^specifications,nature of operations, industrial(Continued on page 187)R E S E A R C H A N D I N V E N T I O NByJOHN WM. BUCHER, "02Chief Engineer, Colorado IronWorks Co., DenverEver since tbe dawn of civilizationman has been dependent on thevarious metals for the advancementmade in our mode of living. Man'ssearch for truth hest exemplified inthe engineer's urge for investigation,research and invention has been aprime mover in our quest for an improvedculture.From the days in the early 80'swhen our first Alumni crossed tbethreshold of our Alma Mater to begina life of self existence from the fruitsof their own endeavor, in their chosenprofession, the urge to do somethinga little different or in a more economicalor practical manner has beenthe incentive for many of us.Physical means for practical researchin the mining or metallurgicalfield were limited at Mines until theerection of the Experimental Plantin 1912, with its laboratories in whichthe students are given practical instructionin ore-dressing and hydrometallurgy;and its research laboratories,with the necessary equipmentand analytical facilities for variousforms of ore testing.The same was true regardingmeans for research and invention inthe Petroleum Option until StrattonHall and the Hall of AdvancedChemistry were equipped with thenecessary research laboratories andapparatus about 1914. We have todayin our most recent acquisition to thecampus, namely Berthoud Hall, aunit for Geology and Geophysicswhich is unexcelled for teaching andresearch in these branches.Time has shown that in spite ofthe fact that our earlier Alumni werenot favored with the advantages ofresearch laboratories and apparatus,nevertheless, their training was suchthat we find one of our ex-students ofthe class of 1888, Kenneth Hartley,the first person to build a gravitymeter for geophysical prospectingcapable of measuring the direct pullof gravity, in amounts as small as onemillidyne.B Y " M I N E S M E N "In the petroleum industry we findMines Alumni responsible for suchdevelopments as the method of introducingan emulsion breaker in keroseneahead of the acid, in acidizingwells; methods of determining oilzones by means of core analysis andmore recently soil analysis as practicedby such companies as theGeologic Standards Co. of Tulsa,Oklahoma,Many Alumni are employed on theresearch staff, or in the process laboratoriesof our leading oil companies.Mr. R. J. Schilthuis of the class of1930, working in the research depart-JOHN WM, BUCHERment of the Humble Oil and RefiningCo. at Tulsa, Oklahoma was recentlyawarded a gold medal by theA.I.M.E. for his outstanding workin research and masterly exposition ofthe same in a technical paper submittedon "Connate Waters" in connectionwith petroleum development.In the petroleum production fieldwe find many graduates in executivepositions, several being Presidents orVice-Presidents of successful andprominent oil companies. Mines gradsare in charge of development andproduction of foreign fields as for examplethe Baherin Island in the PersianGulf where an oil pool with itsgathering lines and transportationlines as well as the off-shore loadingterminal and refinery were developedand erected by a Mines Alumnus,William E. Newnam of the classof '96 was the inventor of the "NewnamHearth" for smelting of lead,which process has replaced all of the"Scotch Hearths". We find twoplants in the U. S. using this process,as well as plants in England, Spain,Germany, Yugoslavia, Russia and theSouth American Countries.Mr. Newnam is the inventor of theNewnam system of molding and loading"pig lead". This system is inuse today at the following smelters:Bunker Hill and Sullivan at Kellogg,Idaho; International Smelting andRefining Co, at East Chicago, Illinois;American Smelting and Refining Co.at Alton, Illinois; St. Joseph LeadCo. at Herculaneura, Missouri;Broken Hill Associated Smelters,Port Pirie, Australia and severalsmaller smelters.In the smelting industry we findan automatic damper for draft controlon Reverberatory Furnaces inventedby an alumnus of the class of'11. A volatilization process applicableto gold ores invented and patentedby an alumnus of the class of'13 in use today by the Chief ConsolidatedMining Co. at Eureka,Utah.In the metallurgical field we findan 1895 graduate, Lewis B. Skinner,the holder of about 35 patents onchemical apparatus and methods,extending over the period from1903 to 1935, during which timehis energies were devoted exclusivelyto research. One of his developments,the Skinner Multiple-HearthRoaster, for sulphide ores, was firstused by the Western Chemical Co. inDenver, and its use today has spreadto raany plants in the United Statesand as far away as the ElectrolyticZinc Co. of Australasia, Ltd.Everyone familiar with the CyanideProcess of gold and silver extractionknows of the Merrill-Crowe VacuumProcess for precipitation of the goldand silver values from cyanide solutions,which was developed hy analumnus of the class of 1900, Eversince graduation, Thomas B. Crowehas devoted most of his time to researchand invention along metallurgicallines and has been the inventoror co-inventor in scores ofpatents.The inventor of the "Packed CellProcess" for the manufacture of sulphuricacid, and the co-author withPhilip de Wolf of the book entitled"American Sulphuric Acid" was E.174 THE MINES MAGAZINE > APRIL 1940THE MIKES MAGAZINE * APRIL 1940 175

L. Larison of the class of '05 who devotedhis life to development and researchwork. Another member ofthe class of '05, R. L. liallett, is thechief chemist and manager of the researchlaboratories of the NationalLead Co. in New York.From the class of '06 we findanother alumnus of whom we maywell be proud, as he holds a chair ofSenior Fellow in the Mellon Instituteof Industrial Research, and is alsoManager of Research and Tests forthe Duquesne Slag Products Co. ofPittsburgh, Pennsylvania. Under hisdirection new and profitable uses ofslags have developed so that we nowfind them being used in cement, asaggregate in concrete, railroadballast, road surfacing and soil liming.We have mineral wool, made fromslag, as an insulator in most of ourmodern homes, also such cast slagproducts as brick, blocks, slabs, tilepipe, etc., used in the building trades.Our director of the ExperimentalPlant at Golden, Arthur J. Weinig,is an alumnus of the class of '08, andunder his guidance and supervisionresearch work is carried on by studentsand alumni for the developmentof new and improved operatingtechniques in ore dressing and metallurgy.Mr. Weinig is the author ofseveral exhaustive publications onBall Mill Grinding in open andclosed circuits and on Flotation ofNon-metallic minerals, all of whichhave been published by the School ofMines as Quarterly publications.If one sbould go into any of thelarger mines in the Butte district, hewould immediately note that theshafts appear to be made of reinforcedconcrete in place of timber.Upon further examination or inquiry,he would discover that the originaltimbers have been covered with castconcrete slabs and then smoothsurfaced,appearing to the casual observerto be concrete piers. Thisprocess of smooth-surfacing mine timbers,as well as a method of conditioningmine air, based on the coolingpower of the surface atmosphere, anda method of cooling water by air toa temperature below the wet bulbtemperature of the air, are inventionspatented hy an alumnus of the classof '12, Allan S. Richardson.When molybdenum sulphide orewas first discovered at Climax, Coloradoits commercial value waspractically nil. It was necessary notonly to work out a practical andeconomical method of recovery, butalso to find uses for the metal andproduce a market for the same. Thereis no doubt that the untiring researcheiforts in processing molybdenumores of an alumnus of this same classof '12, Alan Kissock, now Vicepresidentof the Climax MolybdenumCo., contributed in marked degree tothe outstanding success of this company,which today furnishes about85% of the world output of this nowstrategic mineral.A visit to the central mill of theEagle-Picher Mining and SmeltingCo. at Picher, Oklahoma or to theplant of the American Zinc Co. ofTennessee at Mascot, Tennessee willreveal that these companies are nowtreating from to 4 million tonsof zinc ore annually by the differential-densitycone process, developedby C. Erb Wuensch of the class of'14. This idea was born at a timewhen the price of zinc was at an alltimelow, which caused it to travelover an exceedingly rough path, andit took extraordinary foresight, ingenuityand patience to bring tliis processout of the laboratory stage to acommercial paying basis.About the same time anotheralumnus of the class of '14 was workingand received patents on a processcovering the use of cyanide in theflotation of metallic sulphides. Todaytbis process is being used by manylarge mining companies, among whichare the American Metal Co. Ltd.;The Anaconda Copper Mining Co. ;The Bethleham Steel Corporation;The Bunker Hill and Sullivan MiningCo.; tbe Consolidated Miningand Smelting Co. of Canada, Ltd.;the Electrolytic Zinc Co. of Australasia,Ltd.; the St. Joseph Lead Co.;the San Francisco Mines of Mexico,the Utah Copper Co., and the HoweSound Co.But why remain within the metallurgicalor petroleum branches forMines men in research? We findone alumnus of 1900 located with theBureau of Mines whose endeavorshave taken more of a philanthropicturn, and who has devoted years oftime and effort to improving thehealth and safety of the miners. Thewriter can remember as far back as1906 when Dan Harrington wastravelling from one mining camp toanother teaching tbe men the basicprinciples of mine rescue work. Todayindustry recognizes safety engineeringto be fully as important asany other branch of engineering.How can we turn to a profit thedisposal of the fine coal that is the resultof modern coal preparation andcleaning? Ten years spent in researchon this problem is ably explainedin a paper entitled "Produc-, tion of Low-Temperature Coke bythe Disco Process" and presented atthe New York meeting of theA.I.M.E. in February 1940. Carl E.Lesher of '08 is the author of thisTechnical Publication which describesthe final success of the processin a commercial way, and the manufactureand sale of the by-products oftar and its derivatives, and the economicsinvolved.Drugs and Pharmaceuticals alsoclaim their share in research as evidencedby one of the class of '13, whohas spent a number of years in researchalong these lines.We have mentioned in a brief mannerthe accomplishments of Minesgrads in research and invention,which have come to our attention.Numerous others have devoted muchtime and endeavor to research invarious branches outside the mineralindustries, and have been outstandingin their chosen field of endeavor anda credit to their Alma Mater.Today the improved facilities atthe Colorado School of Mines for investigationand experimentation innew processes are the means of givingto the scientific and industrial worldyoung graduates who have been instilledwith the spirit of progress andan inherent desire for adventure alonguntrodden paths.It is to these young men weconfidently look in the future for evengreater developments in research andinvention.(Continued from page 170)Operated in attempting to have themurals donated to the School.However,after several weeks of effort itwas learned that the murals could notbe donated under the laws of Californiabut must be sold for a sumwhich amounted to $1,500.00.

C O N T R I B U T I N G T O T H EM I N I N G I N D U S T R YIMPORTANCE OF THE GEOLOGICALAND GEOPHYSICAL ENGINEERByHUGH M. CONNORS. '22Mining EngineerDenver, Colo.Civilization and mining have gonehand in hand ever since the beginningof time. Without the mineral industries,manlcind would still be plowingthe ground with a sharp stick,reaping his grain with a cradle, threshingit with a wooden flail, wearing abreech clout and living in a skin tepee.And, should any skeptic try to tellyou that mining is a declining industry,remind him that in tbe lastforty years, more metal of all kindshas been produced in tbe world thanwas produced from the dawn of historyto 1900.Xhe recent rapid advance of themining industry has been principallydue to the education and its applicationby the mining engineer. It mightbe well to look into the qualificationsof this individual who is responsiblefor so many of the things we enjoy today.As he must be able to "pitch histent" in any of the far distant placesaround the world where minerals arefound, he may have to establish andbuild his own community which mightmake him virtually dictator over manylives necessary to the successful carryingout of his program. Besides hisduties in connection with his miningoperations he is shouldered with theresponsibility of tbe community he hasbuilt. In such case he would have todirect tbe civic affairs of the community,involving problems in housing,sanitation, water supply, transportation,education, recreation, hospital,religion, human relations andmany others.To withstand all this responsibilityhe must have a rugged constitution, beable to think, plan and perform accuratelyand carefully. He must havea general understanding of mechanical,electrical, metallurgical, civil, and geologicalengineering. He must be endowedwith a vivid imagination whichenables him to visualize the characterand extent of ore deposits ahead of hisexploration and development work tolocate such deposits with the smallestexpenditure of time and money.Besides these qualifications he mustbe possessed with a keen insight intothe human nature of many nationalitiesto successfully handle the laborproblems that he will be continuallyconfronted with. The man who said,"I am only human, j'ou are super human"must have been referring to amining engineer.The Colorado School of Mines hasbeen training Mining Engineers since1879, but at that there are only ahandful compared with the graduatesof some of our larger universities. Notwithstandingthis fact, the distributionand influence of "Mines Men" isHUGH M. CONNORSworld wide. They are found fromone end of the Americas to the other,from Australia through the MalayStates, Dutch Indies, Philippines, India,China, Russia, European countriesand on through Africa to SouthAfrica.In all parts of the United States,Canada, Mexico and Central Americawe find "Mines Men" directingimportant operations in Copper Mining,Lead Mining, Zinc Mining, IronMining, Coal Mining, Gold Mining,Silver Mining, Molybdenum Mining,and many minor metals besides manyof the non-metallics. In the majorcompanies, such as Anaconda, GoldenCycle, Tennessee Coal & Iron, St.Joseph Lead, Lake Shore Mines,Highland Mary, Bunker Hill & Sullivan,United States Vanadium, SanLuis Mining, Mex., Kelowa Exploration,Canada, Woodward Iron Co.,Climax Molybdenum, Idaho Maryland,Empire Zinc, New Jersey Zinc,Mazapil Copper, Mex., North Butte,National Zinc, Hudson Bay Mining& Smelting Co., A. S. & R. Co., CombinedMetal Reduction, PittsburghCoal, Phelps Dodge Corp., MiamiCopper, Union Pacific Coal, NewYork & Honduras, and many otherswe find that much of their success isattributed to "Mines Men".In South American Countries ofany mining importance where majorcompanies are operating, you will find"Mines" well represented and "MinesMen" responsible for much of the successof those companies.The success of gold mining in thePhilippines from its first inception islargely due to "Mines Men" who arefound in responsible positions with allof the major producers. Two LocalSections of "Mines" Alumni are wellestablished on the Islands andprohably have the largest representationof any American colleges.In China you will find "MinesMen" directing many mining operationsand in Russia they played animportant role in the "5-year plan"until it became dangerous to remainin that country longer. On the islandof Cyprus, we find the operations ofthe Cyprus Mines Corporation underthe direction of "Mines Men" whohave been responsible for its successfrom the start. In South Africa wefind "Mines Men" with such majoroperations as South West Africa Co.,Debeers Consolidated, InternationalEngineering Corp., Worcester GoldMine, Golden Valley Mine, RhokanaCorp., and many others.And so it goes, due to their provenabilities for successful operation ofmines under most difficult conditions,in not only tbe Americas but in allparts of the world, "Mines Men"have gained an enviable reputation.ByW. A. WALDSCHMIDTAssociate Professor of GeologyColorado School of MinesExploration and discovery of theworld's vast and hidden mineral resourcesare no longer undertakingsfor amateurs, but tasks for mentrained in the fundamentals ofgeology and geophj'sics.Previously to the last generation,discoveries of mineral deposits—metallic, non-metallic, and fuel—were made in great part by men withlittle scientific training. Yet, thesemen, endowed with perseveranceand a lust for adventure, combinedtheir smattering of knowledge withcommon sense or instinct, and foundby digging, or by sheer luck, many ofthe world's great mineral deposits.The compilation of facts relativeto mineral deposits thus discoveredformed a basis upon which otherscould guide their exploration activitiesmore efficiently. Year after year,this accumulation of facts, publishedand unpublished, led to the propoundingof theories about the origin andaccumulation of oil and gas, theoriesof the origin of mineral deposits,theories of coal formation, andtheories of earth structure. Thesetheories, as well as numerous relatedfacts and postulations, are today embodiedin the broad subject of geology—a subject vital to the mineral industries.But geology has become sucha complex subject that it must nowbe divided and subdivided intonumerous branches such as mineralogy,petroleum geology, mininggeology, paleontology, micropaleontology,petrography, optical mineralogy,mineralography, and others.Thus, while the student of a generationago covered the subject of geologyas a whole, the student of today mustnot only study the broad phases, butmust choose a branch in which tospecialize.The application to exploration activitiesof geological knowledgegained by study is also becoming morecomplex. During the early days ofpetroleum production no systematicmethod of exploration was in practice,but after tbe establishment of proofthat oil and gas accumulated inanticlinal structures, discovery of oilfields grew by leaps and bounds. Inmany regions anticlinal structureswere easily recognized, mapped, andsubsequently drilled. Some of thesestructures were located by geologists,but others were located by men untrainedin geology.Since tbe most apparent structureshave been located and drilled, thetask of locating additional anticlinalstructures and other types of traps isbecoming more and more difficultletus say, the easy geological mappinghas been completed, and the difficultmapping now confronts us. SurfaceW. A. WALDSCHMIDTsurvej'ing now has to be supplementedby core drilling; microscopic studiesof cores and cuttings, including theidentification of micro-fossils; geophysicalsurveying; and hy studies ofregional geology and paleogeography.Similarly, the application of geologyand geophysics to the exploration forore minerals is becoming more intricate.The early-day prospector followedthe crowd and depended onluck, the experience of others, and onhis "Grub Stake". The present-dayprospector, who should be a geologist,must rely on surface mapping; studiesof trends; application of theories ofore deposition; geophysical surveys,and core drilling—but he too musthave a "Grub Stake".In the development of a new or anold mine much detailed geologicalwork must also be undertaken. Petrographicexaminations of the ganguerocks and examinations of polishedsections of the ores must be made inorder to determine the mineral relationshipsand grain sizes which mayhave a direct bearing upon the millingof the ore. Such work must, orshould be done previous to milling,and should be carried on during theprocess of milling in order to maintainbetter control.Naturally, the work of the geologistin mining may overlap the workof the mining engineer, or the metallurgist.In many cases the work ofthe geologist may he done by the miningengineer, or the work of the miningengineer by the geologist. Likewise,some of the work of the metallurgistmay require a knowledge ofsome phase of geology. Because ofthe overlaps of mining, metallurgical,geological, and petroleum engineering,it is necessary for a young manto receive basic training in all ofthese subjects, but to specialize in one.Such training is given to MINESmen. A geological engineer is trainedin the fundamentals of geology, andis allowed to devote extra time tospecializing in some phase of this subject.In addition, he is trained inthe fundamentals of other engineeringsubjects. Thus, he leaves theschool not only with a basic trainingin his selected profession, but alsowith a broad training that permitshim to branch into other phases oftbe mineral industries aside from exploration.Some may say that MINES menwho receive the degree of GeologicalEngineer, which also embodies trainingin geophysics, are, when theygraduate, merely amateurs in theirfield of endeavor. But, it should beremembered that they are trainedamateurs, well grounded in the fundamentalprinciples of engineering, andthat with this equipment and additionalexperience they will soon reachthe rank of professionals. This contentionis supported by the number ofMINES graduates who are holdingresponsible positions in the geologicaland geophysical professions throughoutthe United States and foreigncountries. Many of these men havegraduated only recently, but with thetraining received at MINES theyhave been able to achieve success intheir chosen field in a comparativelyshort period of time.ISO THE MINES MAGAZINE -f APRIL 1940THE MINES MAGAZINE APRIL 1 940181

" M I N E S M E N " I N M E T A L L U R G YByDONALD DYRENFORTH. '12Assisfanf Manager, MetallurgicalDivision, Dorr Co., Denver, Colo.Metallurgy includes the separationof the minerals from the gangue, thereduction and refining of the metalsfrom the minerals and the preparationof the metals for the manufacturerand the arts. The future metallurgistobtains his fundamentals at "Mines"that enables him to take the productsfrom the mines and transform theminto useful alloys or metals. By reasonof his physical and chemicalknowledge be is able to devise processesby which he changes the productsof nature to those of man.Who are these men of magic whotransform the works of nature? These"Mines Men" in metallurgy? Theyare the men who go on! And rightfullyone has good reason to wonder attbe character of men performing suchachievements. There are some menwho can obey orders; and there aresome men who can get things done.It is well to be obedient; it is betterto be resourceful. The resourcefulman keeps trying: where the other manquits, he begins. His motto, "wherethere is a will there is a way", andhis determination to win lures himever onward to greater accomplishments.Of such are "Mines Men" inmetallurgy.Glance through the Alumni Directoryand you will find there is a treatin store for you. Probably you havenot sensed it; neither did I, but neverthelessit is there. Impressively, thechemistry of solutions as a metallurgicalpursuit is far and away the leaderin attracting men from "Mines".Cyaniding, leaching, flotation, smelting,steel, alloys, refining, plastics;these are all glamorous sirens whichcall out to resourceful men.The urge for gold and silver isuniversal. The way was opened withthe discovery and application of thedissolving power of weak cyanide solutions.Disseminated and low gradematerial could be economically workedwhere previously only rich concentrationswere sought. Look at your mapof the world: America, from the Artieto the Argentine; the Philippines;Australia; the East Indies; Africa;each is noted for its production of theprecious metals in the cyanide processand each, has its quota of metallurgicalmen from Mines.So also can you spot these men inthe steel centers of the United States.There are not many in steel elsewhereand for two reasons: Steel is a nationalcommodity and its heavy tonnagehome is in these United States.Not so much so non-ferrous smeltingand leaching. Like cyanide theyare more international in their aspectsand metallurgical men of Mines havegone far afield in answer to the callfor energetic and resourceful souls.DONALDDYRENFORTHIn the smelting of lead, copper andzinc ores you will find that much inthe advancement of processes andmethods originated from the mindsand labor of Mines Men, some ofwhom have practically devoted theirlives to the invention of more efficientmethods and equipment which has returnedincalculable profits to themetallurgical industry. The article on"Research and Invention" found inthis issue will give the reader moredetailed information.Allied with steel are the alloys andhere perhaps is the field in solutionswhere downright ingenuity and doggedpersistence have produced someoutstanding workers. We know of theneed for molybdenum, of manganese.chromium and tin; aluminum, zincand beryllium; tungsten, and magnesium.Many years ago this needwas sensed by metallurgically trainedmen of Mines and here and there inthe Directory you can spot names thatare synonomous with these alloyingmaterials and their development.Somewhat newer, are the plasticsand fewer the names that are found.But plastics, in infancy now, partlyparalleling the alloys, will convergewith them and draw on the men whorespond to the lure of that game.Plentiful, too, are names in the fieldof ore dressing and here again theaspect is more international than local.The majority tonnage of metals is,by all odds, a product of the art ofthe ore dresser who, from the sortingof run-of-mine to the dewatering ofmicron size floated particle, imposeshis will on the process and begetseconomic success. The ore dressersfield is the world and he is a part ofthe responsibility for economic successwhether he be operator, sales engineer,equipment manufacturer, or executive.When you've gone through the listingof names and found the metallurgicalmen, you are interested inknowing their ages and the j'ear of theclass they are in. It isn't surprisingto see in checking by classes and yearsthere are many young men who areprominently identified in all of themetallurgical trends. This holds trueof the teachers, with whom can beclassed the development and researchmen and inventors. It has been saidthat teaching is the most honorableoccupation in which anyone can engage;the most self-respecting businesson earth; the teachers' influence, themost far reaching of all. In a somewhatdifferent way, but nonethelessfar reaching and profound, the men indevelopment and research and withpractical vision leave their impression.Their's is the work of forging the toolsfor the workers the teachers turn out.All are there fn the Directory fromthe earliest groups up to now.Of all rules that govern the activitiesof the metallurgists—the MetallurgicalMen of Mines—three aresure rules for success. The first is:Go on. The second is: Go on. Thethird is: Go on.182 THE MINES MAGAZINE ^ APRIL 1940ByCLARK F. BARB. '25Professor of Petroleum EngineeringColorado School of MinesThe question is constantly beingasked, "What does the engineer doin the oil industry?" or it may be rewordedto ask what the oil companiesexpect of their engineers ? Tbeanswer to the question isn't easy.Usually there is a counter question.What kind of an engineer is referredto? By way of comment it may besaid that the oil industry employsmechanical engineers, productionengineers, civil engineers, chemicalengineers, valuation engineers, gasengineers, refinery engineers, miningengineers, metallurgical engineers,geophysical engineers, geological engineers,lubrication engineers, sales engineers,electrical engineers, and justplain engineers.The reason for the employment ofmen trained in such' a wide field ofengineering and science is simply becausethe oil industry is large andcovers a wide range of activities.Obviously, no one man could coverthis entire field with any degree ofsuccess. Each branch of engineeringor science requires a specialist with abasic training which is common to all.There will be no attempt to outlinethe exact duties of each class of menmentioned above. In most of thecases the type of service is obvious.The electrical engineer for examplehas a very specialized field and it isout of place for a man with only afew general courses in electricity toattempt the design, construction andoperation of a high voltage powerplant. (Or at least such is theopinion of this author.) However,the oil industry often has need forTHE MINES MAGAZINE ^ APRIL 1940CLARK F. BARBheavy duty electrical equipment andemploys electrical engineers to handleit. It would probably be asdifficult for the electrical engineer todesign a multi loop gas line or tocalculate the reserves and presentvalue of a partially drilled oil field.The chemical engineer, speciallytrained in physics, chemistry andthermodynamics could design a crackingplant or figure the thermal reactionof a polymerization process buthe might have trouble in predictingthe rate of edge water encroachmentby Darcy's law and some prorationformula.A geologist, or more properly, geologicalengineer has a very definiteplace in the industry in locatingprobable or likely places to drill. Hefigures this from his concept of thelaws of oil and gas migration andaccumulation. His knowledge is alsocalled upon in figuring probable ratesof fluid movement through the undergroundreservoirs. He is immediatelyin the realm of production and shouldknow his laws of flow through porousmedia. The oil content of a reservoirmight he ever so many millionsof barrels but if the sand is so tightthat commercial production cannot beattained, the field is worthless. (Someof the Berea fields of Ohio are goodexamples of this.) But this samegeologist might be at a loss in explainingthe theory of lubrication to acustomer or in formulating an alloyfor deep well sucker rods.In the Petroleum Department atthis institution the men are givensome specialized training in eitherpetroleum production or in refining,according to the particular desire ofthe individual. They have the basicwork, common to all options, ofmathematics, physics, English, chemistryand related sciences. Of these,in the opinion of the author, physicsis paramount. Without an understanding,and this means more thanjust the memorizing of formulae, ofphj'sics a raan is stopped.In order to use his physics he mustknow his mathematics. In order toexplain his ideas he must be able touse his English. And so the basicfoundation is built. This idea of"fundamentals" has been discussed,written about, talked about, arguedabout until the very expression hasbecome trite. However, it's stillfundamental.Upon this basic training is givensome general work in the petroleumindustry. The idea is to give the man,production or refining, a bird's eyeview of the industry. Make him atleast cognizant of the relationshipand interlocking functions of the Exploration,Development, Production,Transportation, R e f i n i n g andMarketing branches of the industry.Make him realize that thruout theentire organizational structure thereis an economic blood stream thatkeeps tbe organization alive.Certain other work is intended toindicate to him the industrial applicationsof his physics and chemistry inthe design and operation of a refinery.His laws of fluid flow and mechanicsare utilized in figuring pipe lines andpotential productions. Special stressis constantly laid upon fluid flow.That might be called the theme songof the oil industry. It is actuated bypumps, moves thru pipes and is controlledby valves.There is no claim that the men arefinished engineers after four years.There has been merely an attemptto indicate to them tbe value ofcourses that two years earlier theywere chiefly interested in for the sakeof the credit in the Registrars office.(Continued on page 223)183

N O N - M E T A L L I C I N D U S T R I E SINFLUENCE IN EDUCATIONAL FIELDSByKENNETH HICKOK. '26Instructor in Departmentof MetallurgyColorado School of MinesThe non-metallic industries offer avery large field for the technicalgraduate. This is evidenced by thenumber of Mines men who haveentered these industries with a resultingbenefit to themselves and theparticular branches of the industrywith which they have becomeassociated. We find that Mines menare holding positions of responsibilityin management, superintendence,sales, and research in many nonmetallicoperations throughout tbeworld.The cement industry has profitedto a great extent through the activityof Mines men. Important cement industriesin the United States andforeign countries have become successfuland large commercial enterprisesthrough the direction of men who obtainedtheir fundamentals at Mines.Potash is another non-metallic industrywhich is utilizing Mines menin all phases of production. The successof The Potash Company ofAmerica at Carlsbad, New Mexico,is largely responsible to Mines menworking on its staff in positions rangingfrom manager to surveyors. Thisvery forward-looking company realizesthe value of technical training inall phases of its mining and millingoperations.The production of kyanite for highgraderefractories is a field which wassadly neglected until a Mines mansaw the possibilities of this material.He now occupies the position of Vice-President and General Manager ofthe Celo Mines, Inc., Burnsville,North Carolina. In addition to theproduction of kyanite, by-products intbe form of mica and garnets representa considerable income for thiscompany. Part of the kyanite isburned to mullite, a very desirablerefractory for many uses wheresevere service is to be met.Phosphate rock production alsoutilizes its share of Mines men, workingin the Florida and Tennesseephosphate fields in positions of responsibility.Since the production ofphosphate directly affects the priceof ham and eggs, wheat, corn, cotton.tobacco, etc., we are all greatly indebtedto these Mines men, becausethey make it possible for us all to eatmuch more heartily and at a lowercost.Limestone is a mineral which weall realize, has such a diversified numberof uses that it would require agood sized library to enumerate them.A few of the more common uses oflimestone are: as one of the majorraw materials in the manufacture ofcement, iron and steel industry,smelter flux, chemical industry, agri-KENNETHHICKOKculture, sugar refining, water purification,glass making and many others.In all of these we will find Minesmen occupying positions of responsibilityand influence.Gj'psum is another one of the nonmetallicproducts in which Mines menare showing the value of technicaltraining. Gypsum wall board, plaster,and insulating blocks have foundwide-spread use in the building industryin the last few years, and, asa consequence, the value of a technicaleducation is being realized more andmore by the producers of gypsum andgypsum products. Mines men in thecement industry are creating a use forgypsum in the form of a retarder forthe set of cement.Kaolin and feldspar materialswhich are widely used in tbe ceramicindustry, are also benefiting fromMines graduates who hold responsiblepositions in companies producingthese materials. Kaolin is used quitewidely in pottery, porcelain and chinaware, and feldspar is widely used inthe glazing of this material to make itmore delightful to the eye as well asresistant to chemical action andabrasion.The sand and gravel industry,while lacking the romance of goldmining, none the less accounts formany of the nicer things of civilization.It is widely used in concreteaggregate, railroad ballast, road surfacing,filter beds, etc. This industryis also benefiting from the technicaltraining of Mines men. These menare not only valuable from the productionstandpoint directly, but alsofrom the manufacturing of equipmentsuitable for handling this type ofmaterial.In a key position with the majorcompany producing natural asphaltfor its many uses, we find a Minesman directing and influencing tbetrend of this industry. It is obviousthat his technical training at Minesfurnished him with a foundation thatenabled him to successfully cope withmany unknowns.Rutile, a compound of titanium,offers another field which is being exploredsuccessfully by a Mines man.While this particular non-metallicdoes not have as great nor as diversifieda use as many others, nonethe less, its use as a flux on weldingrods and in paint pigments hasassured it of a place in the industrialsun.In this short sketch about tbe influenceof Mines men in the nonmetallicindustries, it is only possibleto touch upon the high spots; however,the spots touched should conveyto the reader's mind the importance ofMines men in this most diversifiedbranch of the mineral industries.The ever widening scope of Minesmen in the non-metallic industry hasproven beyond a shadow of a doubtthat technical training is a valuableasset to this industry and largely responsiblefor its rapid expansion. Wemay expect, as time goes on, more andmore Mines men will find this fieldof endeavor to possess interest andvalue, not only to themselves, but toan increasing number of the publicat large.ByGEORGE W. THOMASCh.E., '26. M.S., '29Golden, Colo.The word "Mines" has become thesymbol of a great educational institution,with a world wide reputation.No matter where you go, to thestranger even, "Mines"-means ColoradoSchool of Mines. As an illustration,two men in a middle west citywere heard discussing mining schools,one was very firm in his statement,"There is just one mining school inthe world worth consideration andthat is 'Mines' at Golden, Colorado."He had never seen the school but knewit from reputation. To his mind itwas the "one and only one," althoughwe know there are other good rainingschools but I will leave the discussionof their merits to others, I will try tostick to my own topic.Naturally a stranger thinks of"Mines" as a large institution withmany graduates in order that it shouldbecome so well known all over theworld and is surprised to find a comparativelysmall group. Therefore tomake up for the lacking in numbers,"Mines Men" must be outstanding inperformance. The high entrance requirementsat "Mines" insures thatcandidates must be properly equipped.This in turn insures an excellentfoundation upon which to properlybuild with tbe fundamentals so necessaryfor the successful engineer."Mines" has always been progressivein its methods of selecting andimparting to its students the importantessentials. A sane, straight forwardattitude is always maintained towardnew and pertinent material whichconforms with modern theory andpractice. It clings to the higheststandards of education. With a broadknowledge of the fundamentals andtheir application so necessary to meetthe many requirements of the mineralindustries, the "Mines" graduateis especially well fitted to impart hisknowledge to others. He has had asevere training which makes hira asupporter of high standards, naturallyproducing the strong incentive foraccomplishment so necessary to reachhis ideals. His influence is onlymeasured by the number to whom heimparts his knowledge and tbis inturn depends upon the wide distributionof "Mines Men" in the teachingprofession.One gets a good idea of the tremendousinfluence played by "Mines"in education by glancing over the vastterritory embraced by Alumni in educationalwork. Among the foreigninstitutions represented are OtagoUniversity, Dunedin, New Zealand;Mapua Technical Institute, Manila,Philippine Islands, and the TemporaryUniversity of Shensi Province,Shensi, China.Not including eleven of the Alumniwho are keeping the home fires burningat "Mines," we have an extremelywide distribution among the institu-GEORGE W. THOMAStions of this country. We are representedby two of our Alurani in eachof the following; The University ofArizona, University of Texas, andMontana School of Mines. Onerepresentative is found in each of thefollowing: Missouri School ofMines, University of Vermont, Universityof Pittsburg, University ofKansas, New Mexico School ofMines, University of Colorado, SanJose Technical School, The Commandand General Staff School atFort Leavenworth, Ohio WesleyanUniversity, University of Oregon,Pennsylvania State College, PurdueUniversity, University of Californiaat Los Angeles, South Dakota Schoolof Mines, and The MassachusettsInstitute of Technology. Besidesthese, "Mines Men" will be found ineducational work in connection withmany high schools in several differentstates as well as many institutions ofhigher learning other tban those mentioned.In making mention of some of theoutstanding leaders in tbe educationalwork who are "standard hearers" for"Mines," the writer feels that he cando no better than to quote certainof their experiences and remarks. Forlack of space tbe following all too fewreferences can be chosen from tbewealth of material available.To Francis A. Thomson, '04,President of the Montana School ofMines we are indebted for the following:"Students of mining engineeringshould guard themselves againstbecoming narrow, dingy-spiritedspecialists. While necessarily devotingthemselves whole-heartedly to theirhighly technical studies, they shouldendeavor to take an intelligent interestin public affairs and in the world atlarge so that they may graduate aspotential professional men and not asfuture artisans in the technology ofthe mineral industry. Roughneckqualities and a hard-boiled appearanceand manner have no value to a futuremining engineer." Also an excerptfrom an address delivered at the AnnualMeeting of Colorado MiningAssociation, Denver, Colorado, January26, 1940 paid a fine tribute tohis Alma Mater, he said, "I am happyto have this opportunity to acknowledgethe very great debt whichI owe personally to the State of Coloradoand its great School of Minesfor giving me my early undergraduateeducation in the profession of rainingengineering."Sound advice by William R.Chedsey, '08, Director of the MissouriSchool of Mines and Metallurgy isas follows: "The soundest advice tostudents of engineering that I knowof is after training themselves asthoroughly as possible and getting outinto practical life, to associate withengineers, but more important associatewith everybody else possible, takea part in politics, join the Chamber ofCommerce, run for office on the schoolboard or anything else, and keep everlastinglyat it provided it does notinterfere with your professionalduties."Adolph S. Walter, '15, Dean ofMining and Metallurgy at the NewMexico School of Mines pays tributeto his Alma Mater in the followingquotation: "My contacts with Dr.Chauvenet, Dr. Butler, Dr. Chedsey,Dr. Patton and Dr. Sherwood assisted(Continued on page 223)184 TKE MINES MAGAZINE • APRIL 1940THE MINES MAGAZINE ^ APRIL 1 940185

Why shouldthere be, for no woman would everhave the audacity to tread upon adomain so outstandingly that of themale sex. Strange things happensometimes and so one of the "sevenwonders" appeared one day as a memberof the class of 1898, a very robustyoung woman from Cleveland, Ohio.At first the tendency was to discourageher but the boys soon found she was"there to stay," so she was finallyinitiated as "one of the gang" and didher share of the "heavy work."As a student she was a wonder andthe records show a 99 in Calculus toher credit. Florence H, Caldwellwas one of the few to obtain the degreeof Civil Engineering at "Mines."Before coming to Golden she graduatedfrom the Ohio Wesleyan Universityand Cleveland School of Art.She was married to Frank H. Jones,also of the class of 1898, April 10th,1901, at Cleveland, Ohio. In a recentletter to the author, Mr. Jonesstated:"There is little to write about herengineering experience . . . . I preferto remember how much help she wasto me in assisting to solve many knottyproblems in my work. Her personalcharacteristics were admirable: loyaltyto friends, kindness and sympathyto any one in distress of mind or body,an unwavering courage. She kept meencouraged thru many rough places."FREDERICK C. STEINHAUERing the Mineral Industries.

According to the DenverPost, in an article April 11th,1934, which in part is quoted, "WhileGrace McDermut was in school nearDenver, her aunt acquired a claimin tbe Razzle Dazzle lode in Colorado.Her aunt and her parents decidedit would be a good plan forGrace to study mining engineering sothat she could look after the mine. . . .She was pleased when it was decidedthat she should enter the ColoradoSchool of Mines. . . . a few M'eekshefore she received her degree in MiningEngineering, the Razzle Dazzlegold mine passed out of the Mc­Dermut family, 'and there I was,' sheexplained, 'with a fancy degree onmy hands and no place to make useof it.' There were no jobs open forwomen mining engineers. Even governmentofficials were inclined to regardwomen engineers in the samelight as the professors at the ColoradoMines regarded a woman student at apredominately male school. However,the year following her graduation shereceived an appointment at the NationalBureau of Standards, being thefirst woman appointed on the Scientificstaff, and the irrst to receive a permanentappointment there, the departmentstating "It was something ofan experiment."The Bureau which had but recentlymoved to its present site, hadabout one hundred employees andthree buildings. The Physical buildingin which most of the laboratorieswere located, was not quite completeas yet. It was a formative period,very interesting, and the work varieda good deal, according to the needsof the occasion. There was much experimentalwork, defining of specifications,designing and building of apparatusand equipment. At first Mrs.Mulligan did draughting, for the mostpart. Later, she had opportunity tocarry on experimental investigationsas well as routine testing and specialwork. For several years she was connectedwith the Electrical division, butmost of her experience has been in thedivision of Weights and Measures,chiefiy in the Volumetric and Densitysection, where she bas been for a goodmany j'ears, and to some extent in theMass section.The work of the Volumetriclaboratory deals with the calibrationof volumetric standards and the testingof precision volumetric apparatussuch as is used by chemists, physicians,and technicians. In the Densitylaboratory, hydrometers are tested.MRS. FLORENCE CALDWELL JONESdensities and the thermal expansionof liquids are determined. Routineapparatus must conform to thespecifications of tbe Bureau and specialapparatus must be of suitable designin order to be accepted for test.If the apparatus qualifies, it is tested,and if found to conform to thespecifications in all respects, receivestbe seal of the Bureau.Reports are made on special typesof instruments, hut they do not receivethe official seal. A great deal ofwork is done for the Federal Government,and State institutions may havetests made free of charge. A nominalfee is charged for work done for thegeneral public. Frequently requestscome for information from the generalpublic; manufacturers and otherscome to the Bureau to discuss technicalmatters.Mrs. Mulligan supervises the testingof the glass volumetric apparatusand acts as alternate for section chiefs.MRS. GRACE McDERWUTMULLIGANThousands of pieces of apparatus aretested each year and as the work is ofhigh precision, the staff must be carefullytrained and the equipment be ofthe best. A good deal of specializedtesting is done. She assists with thedeterminations made at the Bureau onthe density and expansion of alcoholwatersolutions, and has done quitea bit of work compiling and tabulatingdensity data of various kinds.Some of these appear in the internationalCritical Tables, some are inBureau and other publications. Occasionallythe work is done upon the requestof a private party where there issufficient need to warrant it."The Bureau received a great impetusduring the war," Mrs. Mulliganwrote, "because of the vital import-NINETTA DAVISance of its work in many ways, andit has continued to expand.

Its membershipis composed of the members ofthe Board of Trustees, President,Dean and representatives from theFaculty of the School; the Presidentof the Student Body of the School;the officers, members of the ExecutiveCommittee and Chairmen of theStanding Committees of the AlumniAssociation. The deliberation anddiscussion of this body affords anopportunity for representatives ofthose four vitally interested parties,the Trustees, tbe Faculty, the StudentBody and the Alurani, to exchangeideas, viewpoints and opinionsin order to determine policies. TheTrustees represent the viewpoint ofthe State and its citizens; the Facultypresents ideas tinged with tbe intellectual,cultural and idealogical backgroundof the academician; StudentBody representatives contribute theenthusiasm of youth with all the hopesof the future and the contribution ofthe Alumni must necessarily be basedupon the practical viewpoint of thoseengaged in professional and businesscareers. Yet from all these diverseideas thrown into the round-table discussionsthere emerges policies andprograms acceptable to all and capableof being transformed into an expressionof service.markable body.Tbis is truly a re­The Council was organized forthe purpose of co-ordinating all thework, functions and activities of theschool and Alumni, so that completecooperation and efficiency could beobtained in the administration of theprograms and the setting forth of thepolicies of the school and its Alumni.Its primary objective was tbe creationof a practical working body to buildthe C S M foundation for theadequately endowing of the school.The general nature of the work oftbe Alumni Council necessitates thatit be held in confidence and for thatreason it is only possible to report onits activities from a general standpoint.It should be sufficient to saythat a systematic investigation is beingcarried out by the Council of allfoundations, groups or individualswho are directly or indirectly interestedin the mineral industries for theexpress purpose of interesting them inthe needs of the Colorado School ofMines.The first raeeting of the Councilwas held March 27th, 1936 and forthe first year tbe Council met oncein every three months. However, thework of the Council during tbe firstyear was found to be of such greatvalue it was decided to hold theCouncil meetings regularly once everymonth, except during the suraraermonths, so for the past three years totbe present time the Council has beenmeeting regularly once a month.It has heen stated tbe startling successof the school during tbe pastthree j'ears dates from the time ofthe inception of the Alumni Council.That is probably stating it too strongly,but there is not any question theCouncil has been a definite andpowerful force in the rapid growth ofthe school during the past four years.The remarkable success of Minesathletic teams during the past yearhad its birth in the intelligentplanning and well directed programadopted by the Council over threeJ'ears ago.When your newlj' elected President,Mr. E. J. Brook, of LosAngeles, California, visited Denverat homecoming in October 1939 heattended a meeting of the AlumniCouncil. His comment on this groupis worthy of including in this articleand I quote from Mr. Brook."I know of no single group whichcreated a more favorable impressionon my recent visit in Denver at homecomingthan did the Alumni Council.Since its formation, various merabershad written me enthusiastic reportsconcerning tbe work of this organizationwhich aroused not only my interestbut curiosity as well. It was subsequentlymy pleasure to attend oneof your meetings as a guest. Thismeeting not only confirmed the reasonsfor all of the enthusiastic commentswhich had previouslj' reachedme, but was a revelation and a sourceof inspiration to me as well. Uponless emotional and more objective reflection,the realization of the tremendouspotential power for servicepossessed by this group was almostoverwhelming in its portent."Once every month at the ArgonautHotel in Denver the representativesof every departraent of the School andits Alurani meet for the expresspurpose of building our great mineralengineering school of the future.188 THE MINES MAGAZINE ^ APRIL 1940THE MINES MAGAZINE ^ APRIL 1940 189

When it wasdeemed certain that the plan for tbeloan fund was sound, a letter solicitingvoluntary contributions was preparedand mailed to every alumnusand ex-Mines man on the associationmailing list. The results of theinitial drive were most gratifj'ing.ByJAMES BOYD. M.Sc, '32,Assistant Professor of GeologyColorado School of MinesOne of the most vital functions ofthe Alumni Association of the ColoradoSchool of Mines is the promotionand furtherance of its FOUN­DATION. Much material has beenpublished in Mines Magazine fromtime to time regarding the details ofits organization. It began to functioneven before its complete establishmentby the Colorado School of MinesAlumni Association May l7th, 1928.It was incorporated under the lawsof the State of Colorado which areparticularly liberal for Foundationswhich provide for educational orcharitable functions. Such Foundationsare free from taxation under thelaws of Colorado. The Alumni Waysand Means Committee who were entrustedwith tbe organization of theFoundation were extremely fortunateto be able to profit by the experiencesand advice of those associated withthe work of many similar organizations.All of those who have studied theincorporation and organization of tbeC. S. M . Foundation are impressedwith its unique and practical plan. Itsconstitution provides that the Boardof Directors shall consist of the Presidentof the School, two directorselected by the Board of Trustees andtwo elected by the Alumni Association.This Board is separate and distinctfrom the School of Mines butthoroughly familiar with the needs ofthe School and how best to administerany funds provided to relieve thoseneeds.The invested capital is handled bya trustee (a bank or trust company)thoroughly versed in financial mattersand best qualified to conserve theprincipal and secure the largest earningsconsistant with safety of themoney intrusted to it. Through theFOUNDATION, funds may be providedto help students obtain an educationat the School of Mines, toendow and maintain professorships,to provide much needed buildings andto insure their maintenance and operation,and for other purposes whichthe donor may specify.Here is how it works—Supposethat John Jones decides to establish afund of $25,000 to help students obtainan education at the School ofMines. The money and securitiesdonated for the purpose are turnedover to a Trustee selected by theBoard of Directors of the Foundation.In the selection of this Trus-JAMES BOYDtee Mr. Jones will of course be consultedand his desires respected. Assoon as definite earnings are establishedby this gift, the Board of Directorswill announce that funds are nowavailable for the John Jones Scholarshipsand will set out how studentsmay qualify for such scholarships.This will all be done according toa plan formulated by Mr. Jones atthe time of making his gift and approvedhy the Board of Directors atthe time of accepting the gift. Undersuch a plan Mr. Jones will go on educatingyoung men for the mineral professionsand in this way build a monumentto his high ideals which will continueto function long after he haspassed out of the picture.Likewise funds can be administeredby the Foundation, for research, forfellowships, for professorships andprizes for unusual attainments.Wealthy people like to donate buildingsto prominent colleges becausesuch buildings are perpetual andvisable monuments to their memory.With a new building must be providedfunds for equipment, maintenanceand the added faculty personnelneeded for the expansion thatsuch a new building entails. Henceit is just as important to provide morefunds for the expansion of the facultyto enable it to continue the highstandards of education which havegiven "Mines" the rank of leadershipthat it has alwaj's held in its particularfield.To establish fellowships wherebycompetent men may do advanced workin cooperation with the research departmentof the School, on pertinentproblems now confronting the mineralindustries, there is always an opportunityto use funds to great advantagewhen provided.Of course buildings are alwaysneeded and the Colorado School ofMines is now in desperate need of aHall of Chemistry, a PetroleumBuilding, a Library and Auditoriumand several other structures madenecessary by tbe crowded condition ofthe School.However buildings do not make acollege great, they are only the toolsneeded to help reach an ideal. It isthe knowledge and teaching ability ofthe faculty that gives the college itsstatus in the educational world. Statesupported institutions are usuallyrather lax in recognizing unusualability in its faculties directly responsiblefor the reputations of itsschools. Salaries are usually fixed atan average level, so in a college likethe School of Mines where genius developedin the faculty is in demand byindustry it is important to establishendowed chairs which pay a highersalary than ordinary. Such salariesgive the professor added means topersue his learning and at the sametime encourages other members of thefaculty to strive for greater attainmentand success. It provides theextra incentive so necessary to highestaccomplishment.What could be a greater honor thanto have one of the principal chairs atthe School of Mines named for one'sself? Let it be the John Jones Chairof Mining Engineering or the HenryAbbott Chair of Metallurgical Engineeringor the Charles Smith Chairof Petroleum Engineering or any oneof several others. The Colorado(Continued on page 223)ByJAMES W. DUDGEON. '13Chairman, Athletic CommitteeMines Alumni have continually inmind, ways and means for the bettermentof the student body at Minesto the end that the mineral industrieswill be furnished with young menwho are better equipped mentally andphysically to cope with the severeconditions which these industries imposeupon them.The Alumni have given muchthought and study to the conditionsfacing these 5'Oung men and to thequalities tbat they should have toinsure greater success when they arethrown on their own resources. Theseolder men have found through theirmany years of experience in combatingthe problems presented to the Engineerof the Mineral Industries, thattwo characteristics are extremely essential—"horsesense and guts". Ithas been found tbat these qualities areusually more highly developed in theyoung lad who has had to combatmany difficulties and hardships andassume responsibilities from his boyhooddays. The boy with the combinationof a mental and a physical developmentis the best equipped to combatin after life the severe conditionsimposed by tbe mineral industries.These young men have not all beenblessed with the necessary income tbatis required to enable them to attendMines and continue both mental andphysical development.About four years ago a group ofMines Alumni working under thesponsorship of the Alumni AthleticCommittee launched a plan designedto assist worthy young students in afinancial way and in this manner toassist them in completing their engi-JAMES W. DUDGEONneering courses and become graduatesof the greatest Mining School in theworld.The plan evolved was tbat of creatinga fund to be known as the"Alumni Loan Fund", This fundwas to be raised thru voluntary subscriptionsmade by all Mines Alumniand loyal supporters of Mines.The plan for the "Alumni LoanFund" was discussed at length withall interested persons, officers of theAlumni Association, and with thefaculty and students at Golden. Itwas conceded by all to be a step forwardin the enhancing of the friendlyand cooperative spirit existing betweenthe Alumni, School of Mines administrativeheads, faculty and studentbody at Golden. It was enthusiasticallyreceived by all Mines menand alumni. They at once discernedthe benefits which would accrue to theColorado School of Mines and MinesDuring tbe second j'ear of operationof the fund the results were evenbetter and thruout last year tbeAlumni Loan Fund proved its worthbeyond all shadow of doubt.During the year 1939 loans to studentsin amounts ranging from $25.00to $150.00 enabled fourteen men toremain in school .and complete theiracademic work, which they could nothave done without this assistance.It will not be amiss to explain themethod by which a worthy studentmay obtain a loan from the fund. Ifhe is an entering student his entrancerequirements must meet the academicstandards prescribed by the school.An investigation relative to his needfor financial assistance is then conducted.If in need of assistance, hemust then be recommended by theC. S. M . Athletic Director as a suitableperson to receive a loan. Hisapplication for a loan is then presentedto the Executive Committee of theAlumni Association for approval. Ifapproved by this committee the loanis made. As security for the loan apromissory note embodying the termsfor repayment of the loan must beproperly executed by the applicant atthe time he obtains the loan.The Alumni Loan Fund has beenin operation about two and one-halfJ'ears. Only two recipients of loanshave graduated during this period.The plan is still in its infancy andexperience figures to determine therate at which the fund will be madeself-perpetuating thru repayment ofloans are not available. We are,however, confident that the loan fundwill gradually become self-perpetuating.In the meantime, however, it isgoing to be necessary to solicit additionalfunds with which to carry onthe good work.We of the alumni association desireto express our appreciation and gratitudeto the many contributors, who bytheir contributions have enabled us tocarry on the program of extendingfinancial assistance to those in need ofsuch help, who are now obtaining anEngineering degree at the ColoradoSchool of Mines. Everyone raustcontinue to do his part toward perpetuatingthe Alurani Loan Fund andthus enable us to continue a task sowell begun.190 THE MINES MAGAZINE APRIL 1940THE MINES MAGAZINE ^ APRIL 1940 191

MASON, DirectorPhysical Education and AthleticsAt the foot of Loolcout Mountainlies a school that for years has trainedthe best engineers in their profession.It is the desire of the Colorado Schoolof Mines not only to train men mentallyfor the profession, but to givethem the physical and social trainingnecessary to successful living.The department of physical educationhas a great interest in all of tbistraining. The department feels thatit bas the responsibility of encouragingphysical and social activities on apar with the mental training.The program of required physicaleducation, intra-mural games and competitiveathletics not only aids in thedevelopment of the body and thesocial graces but also improves theintellect,, the latter, of course, all important'notonly in the education oftbe engineer but of all students ingeneral. The opportunity affordedyoung men to_ express themselves indifferent physical activities such asinter-coUegiate competition, is boundto be an impetus for other studentstoward activities such as intra-muralsor selected activities provided in thegymnasium, field house or playingfields.Today, the Colorado School ofMines has an athletic plant that isfast developing into a splendid unit.With the new field house, opportunityis given for such activities as, track,baseball, wrestling and minor sportssuch as badminton, volleyball andsimilar activities. During inclementweather this past spring a number ofthese sports were carried on at thesame time with very little confusionand in no way did any sport interferewith the other. This is bound to increaseinterest in physical fitnessthroughout the school.With the enlargement of BrooksField to the west, it has been possibleto construct one of the best tracks inthe country. The last load of cindersfor the track has been spread andwith the mixing of clay for bindingpurposes, the school is ready to be thehost for the Conference Track andField Meet on May 24th and 25th.Incidentally, this is the first time inthe history of the school that this hasbeen possible.Four concrete tennis courts havejust been completed. These liesouthwest of the field house andwhen landscaped the natural rockwhicb has been used for rip-rappingon the south and west sides, will beone of tbe beauty spots of the campus.This will add another opportunityfor students to take part in some activitythat they enjoy doing. Whena student is able to exercise for hisown enjoyment, he gains double thebenefit from physical exercise.The baseball field has been constantlyimproved until at the presentJOHN H. MASON• New Field House.time it is in the best condition since itsconstruction. Plans bave been formulatedto sod tbe thirty acre tract andto rip-rap the south and west sideswith natural rock constructed intoseats. This field will be availablenot only for baseball, but also forintra-mural softball and touch-footballand a much needed practice spacefor varsity and fresbman football.It takes time and patience for thecompletion of such splendid facilities,but with the cooperation of all concernedit will not be long until theschool can have one of the best athleticplants in the country.At the present time the School ofMines is represented on tbe athleticfield with teams of football, baseball,basketball, track, wrestling, swimming,golf, tennis, ice hockey, fencing andsoccer. There is not another schoolin tbe region that gives its studentsthe opportunity to participate in sucha large variety of sports. The intramuralprogram includes such activitiesas touchfootball, basketball,volleyball, wrestling, boxing, swimming,tennis, track, softball, horseshoes and any other sport that the studentbody wishes to introduce.These activities provide an opportunityfor men of all dispositions andteraperment to meet and find physicalactivity which is so necessary for thedevelopment of tbe intellect and body.Of what good is mankind withoutboth? This department wiil continueto improve the methods in its phaseof training of the Engineer—andCHAMPIONS!W a n t e d ! MEN FOR JOBSW a n t e d ! JOBS FOR MENIt is the function of that branch ofthe Alumni Association known as theCapability Exchange to correlate thesetwo items and to bring suitable menin contact with suitable positions.The services, therefore, are two-foldin that the interest of the employer isserved as well as the interest of thealumni member. In tbis work ofcorrelation, however, we are veryoften seriously handicapped in that wedo not have complete up-to-date experiencerecords of all the School ofMines graduates. At all times wehave certain small lists of men whoare unemployed, most of whom are inmore or less desperate need of quickservice. This class is apt to take ongreater importance than it truly meritsfor the reason that if the Exchangewere functioning at a high efiiciency,it should be possible to place a goodman in a better position even thoughhe might be at tbe time employed. Byimproving the situation of this oneman a place would be open for a secondman who might also be suppliedfrom our ranks if we had a more detailedknowledge of the ability andqualifications of our members.In work of tbis kind we mustnecessarily rely on the honesty andsincerity of the applicant on the onehand, and on the judgment and integrityof the employer on the otherhand. In order to secure greatestsatisfaction for all concerned, there isnevertheless a certain amount of responsibilitywhich fails on theCapability Exchange on account ofthe fact that our recommendations aregiven careful consideration and arerated as being authentic. To meetthis responsibility, we attempt to intervieweach applicant either by mail orby personal contact and, in this wayto learn as much as possible of hischaracter and ability. Complete officerecords are indispensable for thispurpose.ByALLAN E. CRAIG, '14Chairman, Capability ExchangeOn the other hand, we have a certainresponsibility to the applicant andwe must know something of thecharacter of the employer in order tosafeguard the interests of our members.We have calls for men in foreigncountries as well as at home. Flere isa young graduate in Nicaragua bitterlycomplaining that conditions are notas he had expected. He wants tochange. This particular man wasn'tALLAN E.placed through our efforts, but perhapsif we had been consulted wemight have found out enough of conditionsto discourage him from takingthe job. At our suggestion anotherman bas made application for a jobwhich proved to be merely a requestfor a young graduate to work atpractically no wages in making examinationsand reports apparently forpurely promotional objects.We have real legitimate inquiriesfor assayers, surveyors, miners, superintendents,and occasionally managers.It seems to be only occasionally tbatwe are able to match the right menwith the right jobs.There seems to be a growing demandfor executives and engineers inindustrial fields not necessarily directlyconnected with mine interests, forwhich our men with their broadfundamental training are well fitted.Openings are sometimes available withmanufacturing concerns in eitherproduction or sales departments,which should eventually lead to executivepositions with broader responsibilities.It is the ambition of the CapabilityExchange to broaden its activities insuch a way tbat all of these outletsfor our members can be drawn uponas the need may arise. We emphasizeagain, then, the importance of keepingcomplete experience records onfile at the Alumni office.The activity of the Capability Exchangecenters around the office inDenver. However, committee membersare placed at distant points fromDenver for the purpose of supplyinginformation to members in tlieir districts,and also for the purpose ofsecuring data on available positionsfor transmission to the Denver office.In addition to active committee members,we are counting on every manwho is gainfully emploj'ed to keep asharp lookout and to keep us informedas to opportunities in his own vicinitywhich may interest some of his fellowmembers. More can be accomplishedby personal contact than by form lettersor circulars, or even an article inthe Mines Magazine. It is impossiblefor the committee members themselvesto reach all possible sources, and weurge you therefore to bear this workin mind individually and to give usthe benefit of your thoughts and effortsto build up tbe service of theCapability Exchange. This appeal ismade to ali members separately, andto the various local sections collectively.194TKE MINES MAGAZINE > APRIL 1940TKE MINES MAGAZINE ^ APRIL 1940 195

McWHORTER, '24District Manager, Goodman Mfg. Co.Denver, Colo.A glance thru the Alumni Directorywill give indication of the surprisinglylarge number of "MinesMen" that have followed the businessof supplying to the mineral industriesthe tools with which theywork. In speaking of tools I meanto include equipment and suppliessuch as hoists, rock drills, compressors,locomotives, tramways, shovellingmachines, conveyors, powder anddynamite, chemicals, and just a hostof other items up to complete mining,milling, preparation plants, smeltersand even manufacturing plants.Mechanization of the mineral industrieshas become an importantpart of it and surely the most potentmeans of reducing production costs.The technical education receivedat the Colorado School of Mines issuch that a great number of engineershas either chosen tbis mechanizationprofession or have been drawn into itby the very nature of their training.Far-thinking manufacturers interviewthe graduating class at Mines eachyear for the purpose of picking out anumber of prospective technicians andsales engineers. These interviews areinvariably done by personal contact,not by letter, reflecting the care andprudence exercised by these industriesin selecting men who are particularlywell suited for their specialty. Manymanufacturers have made tbe remark: "I don't know what it is butthere is a certain intangible somethingfound in the man from 'Mines' thathas proven to be very essential, aquality not found in men from othercolleges".CEDRIC E. McWHORTERIt is an established fact that menfrom Mines are more generouslyscattered thru the mining equipmentindustry than men from any other oneinstitution and I believe I know why.First of all, a man who enrolls atMines almost invariably reaches thisdecision only after a lot of hard,straight thinking, with a full realizationof the energy and personal disciplinerequired to complete his 4 hardyears of study. He is, therefore,already a man of purpose andequipped to make a logical decision.Success in any business demands agood generous portion of purposeand logic, better known as clearjudgment, "horse sense" or whathave you. I have heard it said by mypeople, as well as by other manufacturers,that a cross section thruthe_ graduating class at Mines invariablyshows a clean cut, energeticman who knows what he wants to doThe well worn term, "MachinerySalesman" or "Drummer" is mostsurely a misnomer. A successful miningexecutive cannot be "sold" anything.He will "buy" it if it willmake money for his company but heis too shrewd to be talked into anythingthat he does not need. Highpressure selling simply won't do. Wemanufacturers call our field men,"Sales Engineers" and we know thatour best men are those who areactually considered "consultants bytheir clients. We train them intensivelyin the application of whateverit is that we build as weli as"what makes it tick." It isn't so importantto know how a set of gearsand a motor are assembled in a machine,but it is vitally important toknow what kind of a job tbis machinewill do when applied to a particularproblem. This is why we wantand use mining engineers. Theyknow after a little experience how toanalj'ze a raining man's problem asrelated to their own particularproduct.Little need be said about the actualtechnical training received at Mines.We all know it is excellent and fullof good sound fundamentals. Ofmore importance is that when wemanufacturers get these new men wefind them already capable of applyingthese fundamentals to our specializedproblems. The old saying,"Make a start, the rest is easy" applieshere. It is important that the"Mines Man" has secured the fundamentalsof engineering and knowshow to apply them—the importantstart.I like to think that these sales engineersand technicians are performinga real service to the mineral industriesand I feel that they are. While theydo not actually produce the minerals,they keep pace with tbe needs of tbeindustry for more efficient raethodsand are constantly developing andintroducing better and safer tools.They have hundreds of thousands ofdollars in annual research expendituresback of them and they are intelligentlyapplying the results of thisresearch to the many problems ofproduction. Because of his start the"Mines Man" fits into the settingwhich the manufacturer has preparedat great expense and effort. The two,through combined efforts, produce aservice to the mineral industrieswhich has resulted in the rapid progressin civilization todaj'. Thus"Mines Men" in sales and distributionsupply tbe "tools" so necessaryfor industrial progress.Shaker Conveyors for Metal MinesThe Goodman Manufacturing Company,4834 South Halsted Street, Chicago,after nine years of intensive developmentand improvement of this system ofmechanized loading, has a line of shakerdrives which is being used very successfullyin both iron ore and copper mines.The shaker conveyor may be used solelyas a medium of transportation in mineswhich use a scraper loader for diggingand loading, or, as is the case in coalmines, it may become a digging, loadingand transporting medium combined by• Goodman Shaking Conveyor.the addition of a duckbill. The duckbillis a self-loading head which is made onlyby Goodman Manufacturing Company butis suitable for use with any make ofshaker conveyor.IN ORE MINES . , . The scraperloader has proved to be a reliable diggingunit, but, under conditions where softbottoms or long distance are involved itis much more effective and profitable toload with scrapers and discharge onto ashaker conveyor, for two reasons: (1)As the scraper drags for only short distances,its productivity is increased; (2)The shaker conveyor, having been designedespecially for the carrying of heavyloads, transports the ore continuously asfast as it is loaded.The narrow width of the troughing permitsvery close timbering. The shakertrough line may be easily and quicklymoved to a new location, ground movements.The capacity of a shaker conveyoris far in excess of most haulagesystems or systems in which the scraperdoes both the digging and the hauling. _Goodman engineers who specialize inthis type of equipment are available tomake a survey of your requirements andoffer their recommendations without anyobligation on your part."Mines Men" associated with GoodmanManufacturing Company in themanufacture and distribution of equipmentfor the mineral industries areCedric E.

Retaining dams constructedeven in freezing weather at minimumexpense and with good control atall times.Essentially the method consists of placingthe coarser tailings (usually tablesands) on the back of the dam with theBotation slimes forming a graded "pad"with the coarser materials on the face ofthe dam. This is easily accomplishedwith two pipe lines, where the table sandsare placed by the outer line and the flotationslimes by the inner. A single linemay be used by proper alternate pumpingand use of the Grigsby Spigots andGooseneck for placing the materials wherewanted.Manifolding of pumps and distrihutionof flow to the various lines are controlledeffectively with Grigsby Rubber-linedPinch Valves.Denver Hydro-ClassifierFine sizing and desliming problems, inboth cyanide and flotation, will find theirsolution in the Denver Spiral Rake Hydro-Classifier. This is an ideal unit forfurther treatment of the overflow fromother types of classifiers especially therake type, or in closed circuit with a regrindmill treating jig or flotation concentrateswhere it is essential to reducethe material to sizes —200 mesh to 10microns.Denver Equlment Company, 1400 SeventeenthStreet, Denver.

Diesel Mine LocomofiveDiesel Locomotives for undergroundwork have been used in Europe for anumber of years, but it remained for TheRuth Company of Denver, Colorado tobuild and introduce them into thiscountry. _ Their first installation was inthe Philippines where they have provento be a great success.Patterson-Ballagh Casing ProtectorThe principal item of manufacture ofthe Patterson-Ballagh Corporation of LosAngeles, California, is the rubber casingprotector marketed under the name ofthe "Patterson-Ballagh Casing Protector."This protector was introduced to the oilwell drilling industry 13 years ago byPatterson-Ballagh, and has now become astandard item of use in almost all rotarywells in the world, that are being drilledto any depth, over 4000 feet. It is offeredin some one hundred different sizes, tofit all sizes of drill pipe and aii diametersand weights of casing. The function ofthe casing protector is to furnish a wearingring on the drill pipe to take thewear against the inside of the casing,and stop the tool joints from contactingthe inside walls of the well. They aremade in larger and longer sizes, to stabilizethe drill pipe, and prevent whip, andincrease drilling speed.The Non-Explosive Mining MethodCARDOX is a non-explosive method ofdislodging coal at the working face, whichemploys the gentle heaving action of expandingcarbon dioxide to bring downthe coal. It operates without smoke,flame, or noxious fumes. CARDOX hasbeen approved as permissible for useunder gassy and dusty conditions by theU. S. Bureau of Mines.The CARDOX cartridge consists of ahollow tube forged of chrome-molybdenumthe paper portion of a twelve gauge shotgun shell, the inner surface of the wadbeing coated with a powder mixture andthe open end being provided with anelastic rubber cap. Fuses from the roundare cut square when trimmed and forcedthru the rubber cap which holds themfirmly against the bottom, A master fusefor lighting Is placed in the shell in thesame manner.This lighter is most advantageouslyused in places from which it is difficult toretreat, such as raises, stopes and workingsreached by ladders. V^ere there iswater dripping, Master Lighters protectthe ends of the fuses until they are spit.Short primers may be used with somesaving in fuse by using Master FuseLighters since the proper period to reachsafetj' is obtained by a master fuse ofsufficient length.The National Fuse & Powder Companyemploys H. M. Cronin, '13 as FactorySuperintendent and R. F. Barney, '35 asFieid Representative,W. L. Maxson, *23Receives Promotion withAllis-ChalmersMr. Walter L. Maxson has been appointedSales Manager and Chief Engineerof the Mining Machinery Divisionof Allis-Chalmers Manufacturing Company,according to an announcement justmade by Mr. Herman Schifflin, managerof the company's Crushing, Cement andMining Machinery Department.In design of the locomotive for undergroundservice it was necessary to completelydivorce it from the common sourceof trouble found in the industrial locomotive.Chain drives were eliminatedand side rods used which make it possibleto put uniform torque through allfour wheels without chatter, q"he wheelsare amply sprung, enabling them to followrough and crooked mine track. Thebest of alloys are used in all parts. Timkenbearings are used for journals andother principal bearings. To get maximumadhesion from every pound ofweight, steel tires are shrunk on cast ironcenters. Automotive type brakes are used.These are only a few of the importantfeatures which have contributed to thesuccessful operation of the Ruth Locomotive.Besides the Diesel Mine Locomotive,The Ruth Company iVIanufactures RuthRod Mills, Ruth Flotation Machines andRuth Laboratory Machines. Full detailsand specifications will be furnished onany of this equipment. Joseph P. Ruth,Ex-'21 is President of The Ruth Company.Led-Plate Thread and Gaslcet PasteThis product, made by the ArmiteLaboratories of Los Angeles, (H, C.Armington, '07) as the name implies, isa pipe thread dope containing metalliclead. It is made in two grades, the No,250 to hold water, steam, alkalies andacids and the No. 251 to hold oils, gasesand hydrocarbons.The use of Led-Plate provides a Compoundthat has "body" to fill the tiny voidsand in extreme temperatures wiil notvolatilize, carbonize or alloy with the contactingsurfaces. It is unaffected by gasesor liquids in the line. It will not disappearas do aluminum zinc and antimony; norcarbonize and "char" like organic Compounds.Led-Plate is excellent for all tight fits,for gaskets, threads and machine pressfits. It is a natural lubricant even afterthe vehicle has been driven off.Led-Plate remains in suspension in thecontainer and is always uniform. It willnot deteriorate with age or use and isunaffected by extremes of heat or cold. Itprevents galling and destructive seizureand is easily applied and can be spreadon thin or thick. It is most economical.Patterson-Ballagh Casing Protectorsare made in the rubber factory of thecorporation, where the complete cycle ofmanufacture takes place, from the cruderubber imported directly for that purposeto the finished article. They also manufacturethe other items that comprise theirline, being the Wire Line Guide, theSwivel Bumper, the Pipe Wiper, the MudGun, the Wire Line Wiper, and the SuckerRod Wiper. In the field of plasticsthey manufacture a Tubing Protector, anda Sucker Rod Protector,A Branch is maintained in Houston,and an office is maintained in New York.Branch stocks and service men are stationedin the principal oil drilling centersof the country, in Canada, and in SouthAmerica. D. G. Miller, '09, is President;J. C. Ballagh, '10, is Secretary-Treasurer;H. C. Armington, '07, is Chief Engineer.•V Cardox Method of Dislodging Coal,steel, capable of withstanding internalpressures up to 40,000 pounds per squareinch. Into one end of the cartridge isthreaded the charging cap, and into theother end is threaded the discharge cap.After a heater has been inserted, liquidcarbon dioxide is pumped through a valvein the charging cap. There are two electricterminals in this cap for connectingthe shot firing cables to an electric squibin the heater.. The discharge cap is equipped withangle ports through which the expandingcarbon dioxide is released at discharge.These ports are so constructed that theyhold the cartridge to the back of the drillhole, A soft steel shearing disc seals thecarbon dioxide in the cartridge until thepredetermined discharge pressure isreached.When current is applied to the terminalsin the charging cap, the electric squib setsoff the chemicals in the heater, andsufficient heat is generated to instantlygasify the carbon dioxide, increasing thepressure within the cartridge. As thegases in the cartridge reach the predetermineddischarge pressure, the shearingdisc gives way, and the gas is releasedthrough the ports.After the CARDOX cartridge has beendischarged, it is returned to the chargingplant and used over and over again.There are over 150 mines throughout theUnited States, Canada and England usingthis method of dislodging coal. John H.Bell, '30, is Vice President of CardoxCorporation, 307 North Michigan Avenue,Chicago, III,Radiant Tube Annealing CoversThe Lee Wilson Sales Corporation,Cleveland, Ohio, manufactures portableannealing covers that may be placed overcut length sheets or coiled sheets afterthey have been reduced by hot or coldrolling in charges of from 60 to 100 tons.The unique part of this equipment is theuse of radiant tubes for firing gas andthus giving a furnace equipment whichhas advantages of electric furnaces plusthe advantage of using gas, which, underprevailing rates may cut the cost per tonfor material heat treated about ^.These radiant tubes burn gas in such amanner that combustion continues throughoutthe length of the tube with an eventemperature along the tube. A spark plugigniter located at the exhaust end ofthe tube adds to the ease with which thefurnace may be lighted up after a shutdown.New equipment manufactured by thiscorporation is an electrostatic precipatorfor the cleaning of fuel gas.Employed by this company is Mr. C. H.Carpenter, '09, Chief Engineer. Mr.Carpenter has spent some eight years inmining and metallurgy, eighteen yearswith the Westinghouse Electric and Mfg.Co., starting with the alloys and scraphouse reclaiming, followed by severalyears in the research laboratory and generalengineering department.Master Safety Fuse LighterThe National Fuse & Powder Company,Denver, Colo, announces the "MasterFuse Lighter" for lighting six fuses withone master fuse.

Last year thiswas a very outstanding number andpromises to be just as good this year.Mmes Men" will contribute most of thematerial for this issue which is beingrounded up by Arthur W. ("Pop") Buell.He will appreciate your cooperation.PUBLIC RELATIONS. Chairman Dyrenforth,while not present, reported thatwhile the members of his committee wereinfrequently in Denver as a group, neverthelessthey were alive to the requirementand are plannmg an outline of activitythat should be well under way beginningwith the Annual Banquet in May.The wide field in which we can functionto advantage in Public Relations coversa number of important possibilities ofwhich I will give only a few. Socialactivities of the Association are primaryand closely allied is Publicity in the Pressand other publications. The value of theSchool of Mines to the State and to thenation brings thought of Chamber ofCommerce and Mining Groups and thesewill be surveyed in the cause.Public Relations presupposes individuals.We Alumni are a group of individualsthat must continually increasein number. Needless to say our trend isto work closely with the Committee onMembership and with every other groupcommittee or otherwise.'RESEARCH AND INVESTIGATIONS. ChairmanConnors discussed the anticipatedwork_ of this committee and results arepromised. There is a great deal ofstatistical information needed in regardto our Alumni as individuals and as agroup, that can be used to advantage bythe Association and its committees inpushing plans for greater service.ATHLETIC COMMITTEE. ChairmanDudgeon stated that the "Mines" Basketballteam had tied with Colorado Collegefor second place, which is a very goodshowing after the many years of defeat.Ihe response for contributions to theAlumni Loan Fund met with a good response,however further funds will haveto be provided if the worthy work of thepast several years is to be kept going.INSTRUCTION, LEGISLATIVE AND NOMINA­TION Committees have made no reportslip to this time.Alumni Council MeetingThe _ regular monthly meeting of theAlumm Council was held at the Areo-Z8th, 1940. Those who attended the meetingwere Dr. M. F. Coolbaugh, EdwardC Hanley, and Frederick C. Steinhauerof the Board of Trustees; Dean JesseMorgan, W. C. Cramer, J. Harlan Johnson,W. A. Waldschmidt, Coach JohnMason, George W. Thomas, KennethHickok, of the Faculty; George YeagerPresident of the Student Body; and FrankC. Bowman, A. E. Perkins, James W.Dudgeon, Russell H. Volk, Dent Lay CLorimer Colburn, Hugh M. Connors, AllenE. Craig, of the Alumni.Athletic affairs were discussed by CoachMason and James Dudgeon and followedby a general discussion participated inby all present. Plans for the Alumni Endowmentwere explained by ChairmanCoibum._ Other activities of the AlumniAssociation were given consideration.Dean Morgan gave a statistical reporton the iinder-graduates of the school andfhe relative standing of the scholarshipstudents to the average of the student202body. Dr. Coolbaugh told of the methodadopted in granting of scholarships at"Mines" and his observation of the effecton the student body. He also discussedimportant research that had been carriedout at the School of Mines ExperimentalPlant.(Continued from page 176)could be spent for such a purpose. Mr.Edward C. Hanley of the Board ofTrustees interested Mr. and Mrs.Barney Lee Whatley of Denver whovery generously purchased them forthe school.The DonorsMr. and Mrs. Barney Whatleyhave made numerous benefactions toeducational institutions. They havea natural interest in mining. Mr.Whatley, a native of Alabama, cameto_ Colorado in 1911. An expert inmining law, he conducted private practicein Breckenridge until 1919. Hewas alfo district attorney for the FifthJudicial District during that time. In19]9,_he moved to Denver where hehas since continued the practice ofmining law and maintained an activeinterest in mining operations. In 1920,he married Gertrude Thielen, daughterof a Leadville mining engineer anda native of Colorado. Thus, thesemining murals were presented by amining family to the Mining School.The C. S. M. SettingThe murals were delivered to theGeology Building on February 23,1940. They were mounted on temporaryframes for Engineer's Day(March 15) and the formal dedicationof the Geology Building andwings. At that time they were displayedin the north half of the mainmuseum room. It is planned, however,that they will be placed along the1940ALUMNI BANQUETTHURSDAY MAY 23, 1940AT 6:30 P.M."Mines Men," members of ColoradoSchool of Mines AlumniAssociation and honored guestswill assemble at fhe UniversityClub, Denver, Colorado to enjoya great celebration andfestive occasion.

S. M . aiumni and of theBoard of Trustees, especially Messrs.Barnett and Hanley.(Continued from page 172)and for 35 years they have heen progressingat an ever increasing tempo,until they stand in the forefront ofthose who apply the latest discoveriesof science to the solution of theirproblems.Costs in metal mining must be reduced^ and this means increasedmechanization of our mines, and theadoption of geological methods, nowknown and to be discovered to thefinding of ore bodies. The metallurgistsmust prepare to handle oresof ever decreasing value, until theextraction of gold from sea water becomesa practical problem, and not avision. Our present faculties in ourmining schools are facing severe andjustified competition from the greatinflux of foreign pedagogues ofgreat competence, that have fled frompersecution in the homeland.This upward surge in the numberof students of mineral technology,may indicate a revival in mining, andaccompanying enterprises that is notyet discernible. Such a revival cancome when industry thrives, unemploymentis checked, business isprofitable, and money is at hand forthe further development of marginalmining projects and the solution ofbaffling problems. We need politicaltranquility in a world of wars, canwe attain it in a life time?This is the challenge of our timesto j^outh. Although the present andpast generations may not have met itsuccessfully, the opinion of the worldis that our doubts are traitors, that wefail of success because we fear to attempt,and that our great hope liesin the accomplishments of our engineers.An engineer is a master ofthe arts and sciences, of ethics andeconomics, a man so cultured that heis at home in the citadels of kings,or in the tents of savage hunters, andis_ competent to construct and administerso that the welfare of humanitymay be safely entrusted tohim.THE MINES MAGAZINP 4^ APBII lo^nFROMTHLo^oca/SectionsW.

However, a Httle thoughtwill soon convince one that a collegedegree is in reality but a secondarystandard, the value of which is ultimatelybased upon the success of theAlumnus. An alumni organization isvital for the success of the School andthe individual. The School is largelyguided by the demands and suggestionsof its Alumni. By becoming activein your local alumni chapter youare boosting Mines, and a boost forMines is a boost for you.'More than ever before in the historyof Mines is it urgent that theAlumni organize themselves, as far aspossible. You can bet your neck, thatColorado U., Stanford, Cal., M . I. T.,etc. aren't going to boost Mities first!It's up to Mities Alumni to boostMines! So let's "^^r^ up" fellows, andattend the local Alumni meetings.Boost Mines, and Boost yourself!THERE IS NO SUNThere are men who toil where there is nosun.In the earth's deep bowels, where everyton, , , , ,Wrested by skill and sweat, and broughtFrom the rock-locked vault which Sodhath wroughi.These men of metal have torn asunder.By muscle, steel, and man-made thunder.They are men of courage, underground.Who serve a master called "The Round"with driving will, that needs no rest.Their homage pay with oath and jestAt roaring drill in oil-drenched mist,_With moil or pick in hard clenched fist.Oh, the men who toil where there is no sunSea fhe world move on with each shift done,As meials gleam and molds are poured;These miners take for their rewardThe glory strong and proud men findIn service given to mankind.And, thus il was—!n former years;The world now bows its head in tears,As metals which helped civiliieReturn to earth—from guns and skies,Are measured now by tragedy,—"So many tons—and lives—at sea".For now, where racing war clouds run.The world stands still; there is no sun.—A.

Over fourhundred visitors, both men in theengineering profession and interestedguests of the school, visited the campus,the great majority remaining for theentire day's program.Registration of all guests began inGuggenheim Hall at 9:00 A. M . At9:30 A. M . technical sessions startedin the graduating departments of mining,metallurgy, geology, petroleumand geophj'sics, where papers werepresented by many outstanding authoritiesfrom the field.Petroleum Department Exhibit.By TED GOUDVISIn the two mining sessions atwhich Prof. J. Burns Read and Dr.James Underbill presided, A. H.Bebee spoke on "Construction andWork of the Carlton Drainage Tunnel";Donald Dyrenforth presented apaper on "The All-American CanalDesilting Plant"; E.

Dr. E. L.DeGolyer spoke on tbe "History ofGeophysics in the United States";Dr. Carl A. Heiland discussed "SoilAnalysis" and J. E. Hawkins spokeon the "Application of Geophj'sics inEngineering". All sessions were wellattended, many of which were filled toLeft to right: President M. F. Coolbaugh,Dr. E. L. DeGolyer, Dr. John T. Barnett.capacity with over sixty or seventy interestedstudents and visitors.Also during the morning, highschool seniors from over thirty highschools in Colorado took a competitiveexamination to win one of five scholarshipsthat were awarded during theafternoon's activities. The quiz wasbased on chemistry, mathematics,physics, English and a general question.Scholarships were awarded on thebasis of the hest grades and the numberof students in the graduating classof the high school.Following tbe technical sessionsand the high school competition,groups of visitors and students wereconducted about all the buildings ofthe campus. Tbe mining building displayedits new complete and moderndust-control equipment, and exhibitsdepicting the study of photo-elasticstresses and showed its display ofhistorical pumping, mining and ventilationequipment.In the petroleum exhibit was seenporosity and permeability testingequipment, octane rating, vaporpressure and specific gravity testingapparatus and a model standard tooland operating field, which was inactual operation.In the metallurgical departmentvisitors were shown how the study ofpolished sections are made; models ofplants and equipment and the operationof heat treating furnaces, iiardnesstesting machines and otherlaboratory equipment. In addition,••>r President Coolbaugh un-veils plaquein Berthoud Hall.The Electrical Engineering Departmentgave a magic show, demonstratedits varied electrical equipment,and showed the school power plant.Mechanical Engineering Exhibit includeda blue-printing machine whichmade souvenirs for visitors, andshowed cut-away models of motorsand machines and mechanical devices.The Mechanics Department in thebasement of the chemistry buildingshowed a working model of theRalston Creek Dam Spillway, apparatusfor measuring friction loss,research work in metallurgical pulptransportation, a turbidimeter and avacuum vapor turbine.The school exhibits were probablythe most interesting ever shown. Agreat amount of time for severalmonths previous to Engineers' Daywas spent by a large committee ofstudents and a number of professorsin preparing these departmental exhibitsfor this occasion.A highlight of the program of theday was the noon activity in the newfield house. Here during the noonhours, over five hundred people hadlunch and examined the twenty-oddindustrial exhibits. The six socialfraternities on the campus cooperatedin serving lunch to the large groupof people.The field house proved to be anideal place for the exhibition of industrialequipment. The followingfirms exhibited, many of whombrought heavy operating machinery toGolden:Gardner-Denver Company—^Automaticmucker operated from a portablecompressor.C. S. Card Iron Works Company—In conjunction with above exhibit,furnished track and ore car.Denver Fire Clay Company—Newelectric assay furnace in actual operationwith large display of products.The Dorr Company—Many fineand beautifully constructed operatingmodels of ore-dressing equipment.Western Machinery Company-—National Fuse and Powder Company—-Newtypes of fuse, caps anddynamite.Morse Brothers Machinery Company—Manytypes of milling and oredressingequipment, the smaller unitsof which were in operation.Heiland Research Corporation—Aseismic recording truck and a portablerotary drilling rig.Allen Bearings Company—A displayof various types and qualities ofbearings.General Electric Company — Acontrol device in connection with acut-away motor.Climax Molybdenum Company—Molybdenum samples of ore tomolybdenum steel.The National Supplj'' Company—Oil well equipment, rock hits, fishingtools, deep hole tubing, etc.Urquhart Service—-An operatingdisplay of Ajax screens, carhondioxide fire extinguisher and otheroperating and model equipment.Colorado Iron Works—Models ofAkins classifiers and thickeners.Mine and Smelter Supply Company—-Thedisplay and operation ofa density controller.The Golden Fire Brick Company—A complete and large display of alltypes of refractories and buildingbricks.These industrial exhibits in the fieldhouse found another valuable use forthe new building, and also gives tothe Colorado School of Mines one ofthe best locations in the country withthe best facilities of display for theshowing of these industrial exhibits.After tire inspection of industrialexhibits, a general assembly gatheredin Guggenheim Hall at 2:15 p. m.Here Dr. M. F. Coolbaugh openedthe assembly with a short welcomemessage, and introduced variousspeakers concerned with Engineers'Day. Following a few short talks,the dedication of the new geolog3''-geophysics building, Berthoud Hallcommenced. Dr. E. L. DeGolyer,speaker of the day, gave the dedicatoryaddress in a survey of the geologicaland geophysical developments of theUnited States. Following tbis talk,the assembly heard several otherspeakers connected with the dedicationof the new building, and prominentguests of the day were introduced.At tbe assembly awards were madeto the winners in the American Instituteof Mining and MetallurgicalEngineers' technical paper contestsponsored by the Colorado Section byMr. Frank E.

He may godirectly into the processing and operationsdepartment where he acts astechnical adviser in problems ofequipment design, and maintenance orof processing. He may design newequipment or rebuild and alter equipmentin use. In any case he shouldknow something of the chemistry ofoil and the reasons back of specificationson products. He must be ableto handle some work in strength ofmaterials and structure design. Heshould have an understanding of theeconomics of marketing and realizethat runs to stills must be subordinateto stocks of gasoline. All of thisaffects the design and operation ofprocessing equipment.The production engineer may becalled upon to dispose of waste saltwater or to maintain pumping equipment._He may need to study problemsm drilling muds or sucker rodfailures. He may have a problem ofheaving shale or floating derrickfoundations. He may need to developa proration formula or to calculate themost economical well spacing. He mavhave an emulsion problem or wax orcorrosion troubles. He may need tostudy the effect of an expanding gascap or encroaching edge water andcorrelate this with his geological informationon the field.

He must knowhis laws of fluid flow, for oil, gas andwater, and mixtures of these.It is obvious that no one man couldbe a specialist in all of the abovethings but any oil engineer shouldhave some knowledge of all andprobably be a specialist in a few.After all, engineering is merely anapplication of principles which aregiven in school. Any engineer shouldrealize that he will never find a casewhere there is a perfect application ofa law or theory. Then he is a goodengineer in so far as he can temper alaw with judgment.

Allan, '!8, President; John T.Paddleford, '33, Secretary-Treasurer, 429 FirstNational Bank Building, Wichita, Kansas.Meetings upon call of secretary.Meetings of the Kansas associationduring the past year have been occasionalaffairs due to the incessantactivities of the merabers. All membersincluding Tom Allan, MontySmith, and yours truly, the secretary,have been very occupied with thefield work of the Kansas oil activity. •The Kansas chapter did have a veryfine meeting at the showing of theMines football pictures and a greatdeal of enthusiasm was shown by allof its members. Those attending thismeeting at President Tom Allan'shouse were all favorably inclined towardgiving the School of Minestheir very wholehearted support inall of its endeavors. Inasmuch as thetotal membership of the Kansas chapteris involved in the geological, promotional,or productional phase of theKansas oil industry, any set time formeetings is impossible as all membersare subject to call for field duty atany time. This, however, does notinterfere with their candid wish forthe success, betterment, and continuedprosperity for their Alma Mater. Theofficers feel that meetings will he calledat opportune times and no set date willbe in order, due to the above conditions.We wish all members of theAlumni Association, however, will feelthat they can call on any of the membersof this chapter and receive thesincere cooperation to any of theirproblems at any time.PRIZE WINNERFebruary, 1940Wm.

SINCE Simon IngersoU built his first rock drill in 1871, ou^ tgineershave continually worked towards one objective: the deve ment ofbetter machines that will do more drilling work for you. Ait igh perhapsnot fully appreciated, this policy has been of practical lefit notonly to all industries that have rock to drill, but also to tho world atlarge, for todays machines drill at least ten times faster c fartherthan their predecessors of 25 years ago.onn^^ ^^i^^iJig had to be done with the rock drills that were available inlyUO, the cost of iron, copper, lead, zinc, and other base metals would• I u greatly restrict their use. Gold and silver mining wouldI be confined to rich deposits. The working of marginal ore bodies wouldI be unprofitable and little development work could be done.rBy lowering the cost of producing all metals, stone and other productsof the earth s crust, fast-drilling 1-R drills have contributed greatlyto today s high standard ,of living. The development of these drills hasbeen made possible by your patronage. Your faith in these drills andyour acceptance of them, have enabled us to spend millions of dollarsfor research which has brought about an advanced design of rock drillsand better materials with which to build them. In many instances I-Rdrill designers have actually been ahead of metallurgists and steelmakers. As a result, many new alloys had to be developed and theseare now also available to other industries.Probably rio other machine must withstand as much abuse as arock drill. Steel strikes steel 1800 hard blows a minute. In addition tothis internal mechanical pounding, most drills are subjected to roughhandling, to the constant abrasion of dust, and to the corrosive actionol impure water.Ingersoll-Rand's experience of nearly 70 years in building rockdrills and its unequalled manufacturing and research facilities are incorporatedm every modern I-R drill. Their practical benefits are to giveyou Drifters, Stopehamers and Jackhamers of high drilling speed lowair consumption and low upkeep costs.AflercoolersAir BlowersCore DrillsCalyxCo rocExplorerDiamondProspectingShafl-work:CompreEHors, AirAir- and water-cooledCombined Engine-CompressorUnifs for Sieam,Gas and Oil DriveDirect-Connecled Electricand BeltedMine-CarMotorcompressorsPortableDrill Steel and JackrodsEngines, DieselINGERSOLL-RAND PRODUCTS FOR THE MINEHoistsAir- and Electric-DrivenAir-Motor (Direct Liit)Gasoline- and Oil-EngineDrivenScraperSingle-, Double-Three-DrumSlusherTuggerUtilityJackbitsand[adcbit GrindersJackbits (DetachableBits)Jackfu rnacesjackmillsJackrods (Drill rodsthreaded for Jackbits)Jack rod ThreadingEguipmentPaving BreakersPneumatic ToolsChippersConcrete VibratorsCore BreakersDrills, Multi-Vaneand PistonGrinders, Multi-Vaneand PistonImpact WrenchesRiveters and Holders-OnSows, Safety FirstStationary MotorsWood BorersWrenches, Torqueand ImpactPneumatic Sump PumpsPumps (Cameron)Boiler-FeedCam-Pump (Rotary)Branch Offices the World OverCentrifugalGeneral-ServiceMineMotorpumpsReciprocatingSinkerReceivers, AirRock DrillsAccessories and HoseAuto-FeedDriftersJackbitsJackhamersMountingsPickhamersPower-FeedStopehamersWagon-Mo untedSharpeners and Furnaces847-5REG, U.S. PAT.oFf-EXPLOSIVES and BLASTING ACCESSORIESFor Ore Mining and Seismic ProspectingGELEX—This is a semi-gelatin type ofexplosive made in two grades having 45% and60% volume strength. It has become a mostpopular explosive for ore mining because itreduces blasting costs.GELEX detonates at high velocity insuringgood fragmentation.GELEX is used effectively in wet work.GELEX produces a minimum of noxiousfumes thereby enabling miners to returnquickly to working faces.ORE MININGDU PONT EXTRA—This is a low density,non-gelatinous type of dynamite madein a number of grades, of which those from40% to 55% volume strength are best adaptedto ore mining.DU PONT EXTRA offers the same attractiveproperties as GELEX except thatit has less water resistance.DU PONT EXTRA gives even lower blastingcosts than GELEX because of its lowerprice and higher cartridge count.Du Pont Blasting Caps, Electric Blasting Caps and Delay Electric Blasting Capsare most dependable. The slandoi-d for use in ore mining."NITRAMON" S is a blasting agent especiallydesigned for seismic prospecting bythe reflection method. It is packed in metalcontainers constructed to permit their quickand rigid assembling into sections adaptedto loading requirements.The metal containers are water-tight thusensuring maximum efHciency of "NITRA­MON" S under water. It is non-freezing, notaffected by exposure to hot sun, and does notproduce headaches.SEISMIC PROSPECTING"NITRAMON" S cannot be detonated byflame, friction, impact, "Cordeau" or "Primacord"detonating fuse, or by the strongesttype of commercial blasting cap. Detonationof "NITRAMON" S requires the use of aspecial primer enclosed in a metal containerdesigned to be attached to the other containerscomposing the charge.To obtain the maximum efficiency, simplifyfield operations and economize on the costs ofseismic prospecting, specify and use "NI­TRAMON" S.DU PONT SSS ELECTRIC BLASTING CAPSare especially manufactured for use in seismic prospecting.
