196 Radio BroadcastMr. Young's speech fromWGY :" Men who talk witheach other daily, with theobject of better understanding,do not fight. Let theseinternational conversationsgo on.Let the work of theengineers go on/' Or, asNeal O'Hara wrote of thesetests in the New York EveningWorld: "It looks likeradio isdoing its best tocloud up the next war."MISSCATHERINE MOOREThe first girl radio fan to reportpicking up the now famous " HelloAmerica" in RADIO BROADCAST'Stransatlantic testsADDRESS BY MAJOR-GENERAL HARBORD TO LISTENERS-IN OF GREAT BRITAINFROM STATION WGY, NOVEMBER, 28TH, 1923The privilege I new enjoy of addressing people of the old and the new world without having even to raisemy voice above conversational tone, is so unique, so impressive, that I am awe-struck at its potentialities .This is indeed an age of miracles. It is only three years ago that experiments in radio broadcasting commandedthe awakening interest of our entire country. People marveled at the wonderful agency which madeit possible for them to capture from the very atmosphere about them the voice and personality of some artistor speaker perhaps a hundred miles away.Since then we have passed through a period of development, so rapid and vast as to place it beyond ordinarypowers of description.To-day, it can truthfully be said that there is not a community in the United Statesto which one or more stations of our comprehensive broadcasting systems do not carry their messages of utilityand varying entertainment. Leaders of political thought, culture, science and the arts are enabled to addressmillions of their countrymen in all walks of life, in city and in country with an ease rivalling the intimacy ofthe telephone.From those across the sea, our kinsmen by blood and tongue, have come your own statesmen in recentmonths, and served by this same genie, radio, their voices have reached millions of our people.And now, scarcely before we have been able to grasp and assimilate the tremendous import oj it all, weare invited to speak to our British cousins across the weary stretches of three thousand miles of the interveningAtlantic.It is a matter of tremendous pride to you and to us that this new accomplishment is the logical outcome ofthe intensive research and development that has been untiringly carried on by scientists in both our countriessince the inception of radio broadcasting.As my voice reaches the people cf England tc-night, my memory pictures the great service and unfailinghospitality that our American soldiers received at your hands, while on their way to France. Ycur splendidcooperation in those trying months will never be forgotten. Nor can we forget how considerate and tender wasyour care for our wounded, and bow our men were welcomed to your homes at a time when perhaps anythingmore than the barest frugality could be ill-afforded by your generous people in the throes of a great war.Our nations are closely cemented by unity of democratic purpose, by the same high ideals, and by a commonlanguage. Let us hope that this first exchange of thought by voice across the broad Atlantic will serve tostrengthen our existing ftiendship in permanent bonds of understanding.The program of this National Radio Week have constituted the first attempt to reach you through organifedbroadcasting, and to receive your acknowledgment from your own broadcasting stations.is the harbinger of a closer tie, more thorough understanding, among the nations of the earth.Surely radioI shall be very glad to hear from those of you in Great Britain who may have heard my voice this evening.This is the President of the Radio Corporation of America, speaking from station WGY on the occasion of thefirst organised broadcasting tests between America and Great Britain tests instituted by one of our publicationsknown as RADIO BROADCAST and staged during our National Radio Week. Thank you. Good-night!
THE WRITER, THE SCEPTICAL GUIDE, AND W. A. MIVELEZListening-inin Mammoth CaveAn Account of the First Radio Tests Conductedin Kentucky's "Eighth Wonder of the World"By FRED G.HARLOWGVENOne Cave, Mammoth, located:in Kentucky, 102milesfrom Louisville; one broadcastingstation, WHAS, in Louisville; onefour-tube non-regenerative loopreceiver; one assistant, W. A. Mivelez; oneNegro cave-guide, tolerant though sceptical.To FIND: Radio waves, deep down in aforementionedcave.PROCEDURE: As Junior Operator of WHAS,I had arranged with J. Emmett Graft, SeniorOperator at the Courier-Journal and LouisvilleTimes station, to have signals transmitted atstated times, and my companion and I betookourselves to Mammoth Cave. While sitting inour hotel room 360 feet above the Rotunda inthe cave, where we expected to make our firstunderground test the next day, we tuned-inWHAS and heard the concert with great distinctness,thus assuring ourselves that our instrumentswere in good working order. If wedid not catch our station down in the mysteriouscaverns we could be reasonably sure that someagency in the earth was acting as a screen orcounter-attraction for the radio waves.The next morning, with the Negro guidewhom the cave authorities had very kindlyput at our disposal, we left the hotel for ourgreat adventure, feeling no little excitement inthe knowledge that we were to be the firstpersons to make radio tests down in what isfrequently called the Eighth Wonder of theWorld.Following a wooded path along a steep declivityfor a quarter of a mile we came at lastto the great entrance, a huge mouth of black-
