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. W. Jones spokeon "Mining Operations at Climax";H. N. Lary spoke on "Problems inValuation"; R. H. Summer spoke on"New Trends in Explosives"; J. A.Bowsher gave a paper on "Engineers— A Comparison" and S. S. Tor presenteda paper on "Aspects of Miningin Turkey".The metallurgy session, headed byDr. Clark B. Carpenter heard fourpapers. L. C. Atchison spoke on"Photo-Elastic Stress Analysis";Franklin Coolbaugh gave a talk on"Problems of Concentrating ClimaxOre"; C. C. Drake spoke on "RecentDevelopments in Chilled Iron WheelManufacture" and H. W. Linhardtspoke on "Western Blast FurnaceOperation".Geologists heard three outstandingpapers. A. E. Brainerd spoke on the"Recent Developments in the LanceCreek Field"; C. E. Dobbin spoke on"Minerals of the World" and J. W.Vanderwilt told of the "GeologicalImportance of Molybdenum". Dr.F. M . Van Tuyl acted as chairmanof the session.Clark F. Barb presided at thepetroleum session where three paperswere given. Paul Torrey spoke on"Slime Hole Drilling"; HerbertTreichler and Herbert Thornton presenteda paper on "Drilling Muds"and Frank Fisher spoke on the "Removalof Peroxides and Ethers".In the geophysics session, DartWantland presided. 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. Briber. One hundredten dollars was given in prizes to stu-V Dean Morgan and winningHigh School students.dents in this local contest. Also, thefive scholarship awards were made byDean Morgan to the winning studentsfrom the morning's competition.Sigma Gamma Epsilon honorary fraternitypresented a slide rule to tbeoutstanding freshman during tbeschool year.Following the dedication exercisesin Guggenheim Hall, the group proceededto Berthoud Hall where a briefand simple ceremony dedicating thenew building was witnessed, afterwhich the building was opened to allvisitors for the first public display ofthe entire structure.Engineers' Day this year was placedentirely in the hands of a committeeof twenty-four students. Its successdepended upon the great amount ofcooperation received from the school,the students and the engineering profession.• Portable Drilling RigHeiland Research Corporation.
