The opening of the transcontinental telephone line has been followed by the extension of “extreme distance” transmission into all the states of the Union, by applying these new improvements to the plant of the Bell System. It is now possible to talk from points in any one state to some points in every other state of the Union, while over a very large part of the territory covered by the Bell System, it is possible for any subscriber to talk to any other subscriber, regardless of distance. Wireless Speech Transmission. During the year 1915 very notable development in radio-telephony, the transmission of speech without wires, was made. On April 4th the Bell telephone engineers were successful in transmitting speech from a radio station at Montauk Point, on Long Island, to Wilmington, Del. On the 27th of August, with the Bell apparatus, installed by permission of the Navy Department at the Arlington, Va., radio station, speech was successfully transmitted from Arlington, Va., to the Navy wireless station equipped with Bell apparatus at the Isthmus of Panama. On September 29th speech was successfully transmitted by wire from the headquarters of the company at 15 Dey Street, New York, to the radio station at Arlington, Va., and thence by radio or wireless telephony across the continent to the radio station at Mare Island Navy Yard, Cal.

On October 22d, from the Arlington tower in Virginia, speech was transmitted across the Atlantic Ocean to the Eiffel Tower at Paris, where the Bell engineers, in company with French military officers, heard the words spoken at Arlington. On the same day, when speech was being transmitted by the Bell apparatus at Arlington to the engineers and the French military officers at the Eiffel Tower in Paris, the telephone company’s representative at Pearl Harbor, Hawaii, together with an officer of the United States Navy, heard the words spoken from Arlington to Paris.
