NEW WONDERS IN WIRELESS RESULT FROM WAR TESTS

high towers will be superseded except for limited special purposes.

The theory most generally held until Rogers demonstrated the correctness of his views, was that impulses hurled into the air from a radio transmitting station and deflected earthward became dissipated, as does lightning, when they struck the ground or water. The Maryland scientist, however, believed that the impulse flowed through the earth as through the air and that it was only necessary to trap and measure them in the ground.

Worked Before War

He had been at work on this theory before the United States entered the war and already had interested naval experts. He offered the results of his work to the navy without restriction and when they were accepted after some demonstrations at Hyattsville, officials say, he was with difficulty persuaded to accept even remuneration for actual time given to co-operation with the government. One of the first steps taken was the request of the navy department, that his application for patents be expedited. This was done.

Some of the main advantages of the Rogers system as developed so far, according to the experts, are almost negligible cost of construction, the intensifying of signals by pointing the sending apparatus toward the receiving station and reduction of static interference. Because of the latter advantage the navy's receiving station at New Orleans, where communication with ships in southern waters swept by frequent electrical storms is maintained, uses the underground apparatus with marked success.

Messages to Submarines

In war a great advantage is that submarines receive messages while submerged, by means of wires trailing in the water.

The Rogers development aroused electrical experts of the government to new efforts to expand and improve radio transmission facilities. Out of the experimental work done with this and other ideas, steady advance has been made under war pressure and Rogers' theories are interwoven with those of other men in the results that are being obtained.
