The Bridgeport evening farmer., 1915-10-01


 United States navy's radio tower at Arlington. Va, late Wednesday night, John Mills. an electrical engineer, sent his voice westward through the 1 air over an ordinary telephone in- i strument connected with a powerful wireless telegraph apparatus. 1 At the naval station at Pearl Is- land, near Honolulu, Hawaii, which is 4,6O0 miles away in straight line, Lloyd Espenschied, another engineer in the service of the American Te1e- phone & Telegraph Co.,. was waiting with receivers at his ears for the mes sage that was to come through the ether-the message which was to be started at least, from Arlington in 1 the hope that it might reach the lit 1 tie island far out in the Pacific. It did.
 Cable Tells of Feat.
 A cab1egram from Honolulu yester- 1 day morning arrived at the com pany's offices here announcing that the feat had been accomplished. The ] fondest hopes of the hundreds of scientific experimenters in the com pany's service had been realized. Espenschied had heard Mills counting: "One, two, three, four!'' and then from one to seven, ana from one to nine, and had reported | numbers which his colleagues across the earth had given him as tests He had heard Mills speak several stn- tences, which he. Espenschied, copied down and sent back in his cable mes sage, to prove that the other en- gineer's voice actually had reached him. % f Yesterday morning the world stood i astounded at the news that on We'd nesday3 afternoon President Vail of the American Telegraph &. Telephone Go. had talked by wireless to San F'rancisco-about 2,50O miles in an air line-to John J. Carty, his chief engineer
 Yet the later talk compassed dis l tance almost twice great. A voice had sped through the air for nearly 5toOO miles. When MT. Vail and the other officers of the company and their scientists got the glad tidings they pointed out happily this vista of the near future:
 Wireless telephone conversation be- tween New York and London, New York and Paris, Berlin, Vienna, Mad rid-even Petrograd!
 Possibilities of Future
 The distance covered by the mes sage to Hawaii was greater than the distance to any of those places, and were it not for the unsettled condi- | ton of Europe because of the war, the experts of the wonderful Ameri- can communication system would be conducting experiments in talking. to those places at this very time. 1 They will talk to the European Capitals as soon as peace is restored and the necessary arrangements for experimenting are made. Had the engineer in Hawaii been equipped with a sending apparatus such as the one at Arlington he could have made immediate vocal reply to his colleague. But as was also the case in the San Francisco test, the station at Pearl Island was equipped lsonly with a receiving "set.' When the next long distance tests are made, each station will have sending and receiving apparatus, so that conn plete conversation may be had.
 But even 4.6oo miles is by means the limit of wireless telephony in the opinion of those who have discovered and developed the new system which the American Telephone and Tele- graph Company has put to use.
 Quite calmly and confidently, Ban croft sGherardi, engineer of the plant, made this amazing prediction yester- day:
 Eventually it will be possible to telephone completely around the globe. You may sit in one booth and speak into a receiver, while another man sits at the next booth and waits for your words
 Your voice will go to San Fran cisco say by wire. It will leap the Pacific through the air and be re- turned to another wire. It will cross Europe by wire, then span the At lantic through the ether and return to another wire here in New Y York which will lead it to your friend a few feet away
 'eOr, if you wish, you may talk to yourself and have the curious ex-
 
 as a sort of echo, after you have ceased speaking. A slight interval of time is required for the voice to travel great distances-say a. fra,c- ton of a second. MT. Vail, the Pres ident, talked to himself by way of Denver. recently, and had the novel sensation of, listening to his words after brief lapse of time"
 De Forest Claims Invention
 All the inventions and appliances less telephony MT. Gherardi said, are the work of the engineers of the A. TT & T. and it's associates, the West ern Electric Company. which is the manufacturing concern of the sys- tenn.
 Dr. Lee De Forest, inventor and ex- perirnenter with wireless telephony and telegraphy, sent out a typewrit- ten statement to the newspapers last night in which he said he had writ ! ten to Secretary of the Navy Daniels, congratulating him on the "epoch- making feat on the part of the navy in telephoning across the continent ''
 This typewriter statement began by saying: t'Dr. Lee DeForest of this city, under whose patents the Navy Department opened transcontinent- al wireless telephone ." It went on to state that the success of this navy experiment." was due to an in candescent lamp generator and said:
 ''I have been devoting the last twelve years to the developing of this lamp principle, and naturally I have Ia fathers interest in the feat per formed by it under the direction of Secretary Daniels
 The De Forest statement did not once mention the A. T. & T.. or any
