WIRELESS WAVES

RESEARCH SOLVING PROBLEMS. (United Service.) (By Cable—Press Assn—Copyright.) NEW YORK, August 9. The echoes of radio signals of a nature that is inexplicable to scientists, but which are promising to reveal new knowledge of the strata 200 miles above the earth, and to ti aid in solving the conditions affecting long range radio work, are being recoided nightly in the University of Chicago. Doctor Barton and an assistant have been photographing peculiar multiple signals between nine p.m. and four a m They believe that the atmospheric conditions of the geographical North Pole, the magnetic pole, and the Aurora Borealis regions are responsible for the echoes. Using an oscillograph, to picture low length waves coming from Germany, South America and California, these two physicists have caught after effects to the main signals which cannot be explained by the tact that signals often go round the world, because they occur from one-hundredth to fourhundredths of a second after the main signals, which is too short for the cir-cum-terrestrial path. The scientists state: “The vagrant wave which we ‘are recording apparently takes an excursion of several thousand niiles more than the direct path from the transmitter to the receiver. This path is unknown, and we are classifying our data in the hopes of co-ordinating them with the phenomena in, or above, the earth s surface, which are capable of bending or reflecting waves along paths shorter than the great circle of the earth.”
