Show Physicist Tells I Of Finding Ore Veins by Radio Radi NEW YORK Oct 28 AP AP pro To add to the puzzling perplexities of twentieth century Inventive genius came President Max Mason of the University of Chicago last night to Inform an engineering group of successful experiments In locating burled buried ore oro by radio The physicist sets up his sendIng sending sending send send- ing and receiving set after arter his party of engineers has cleared l the surface of brush President Mason lason explained to the New York section section sec sec- tion of ot the American Institute of Mining and Metallurgical Engi Engi- Then he sends a message down Into the earth parth and the rocks rocus and ore send back hack signals in reply Such me messages sages properly transmitted transmit transmit- ted and intelligently deciphered pass through the earth about as readily as a sound travels the air all Soils rocks and ores hidden beneath beneath beneath be be- neath the tho surface differ in ill many r respects and these differences may maybe maybe be made to furnish the physicist working from the surface with a a. clue President Mason explained To bring these differences Into action the physicist Greatest some kind of an effect which penetrates Into the ground and Is distorted and md reflected reflect reflect- ed when It meets boundaries between between between be be- tween different sorts of oC underground underground under under- ground structure The most successful experiments with electrical methods of detection detection detec detec- tion have been obtained at less than feet depth he said advising skepticism when working ranges ranes of feet or more are attempted The gr greatest uncertainties are those met in the exploration of virgin lands for new ore bodies |
