HUMAN VOICE ACROSS
(Continued from Page One)

Bancroft Gherardi, engineer of the
 plant of the company, also talked into
 the telephone and were heard at Mare
 Island and had their words repeated
 back by MT. Carty there Others
 present were ex-Senator Murray w
 Crane of the executive committees:
 General Superintendent of Plant F. A.
 Stevenson, and Engineers o. B. Black
 well and H. P. Charlesworth, the tranScontinental wireless employees
 Radically new ideas in wireless work ing have been invented and developed by the general engineering staff of the A. T. & T., working to this end by direction of President T. N. Vail; but it is interesting to note that in starting this first message on it's flight through the ether to the Pacific coast. President Vail used a Bell tele- phone designed for wire working.
 At 12:4S eastern time, President Vail, surrounded by a few officials of the A. T. & T., picked up a Bell transmitter and called into it:
 Hello, Carty, this is MT. Vail"
 In spite of the fact that the words went by wire to Washington and then leaped through the air to the Pacific coast, Engineers Carty's reply came back almost instantaneously: This is fine, this is wonderful" and the groups of men gathered at opposite sides of the continent knew that wire less transcontinental telephony would henceforth be numbered among the miracle of modern science. After an conversation with MT. Clarty, MT. Vail was followed by others pres ent and in all cases the takers were informed by the listeners at Mare Island that their voices were distinct and recognizable. Earlier in the day, a similar and equally successful dem nostration took place at Arlington. where engineers of the American Telephone and Telegraph and officials of the army and navy talked direct to Mare Island by wireless.
 The Bell wireless system is not yet fully installed at Mare Island. the re- ceiving apparatus only being in posi- tion there; hence it was impossible for messages to be telephoned back by wireless, but all the messages sent by way of the Arlington tower were re- corded at Mare Isalnd and their re- ceipt fully confirmed by the officials in their reports by wire.
 Col. Samuel Reber who is in charge of the aerial signal service of the army, who was present at the demon stration in Washington and talked by wireless to San Francisco, said last night:
 'The recent successful transconti- mental transmission of speech between Washington and San Francisco marks an epoch, not only in technical achievement, but also in the devel oph4ent policy of a great corporation. When conversing some two years ago with MT. J. J. Clarty, the chief engineer of the American Telephone and Telegraph, on the economic des- tiny of the telephone, he stated one of the goals sought by the company was the development of a truly uni versal telephone service. With this object in view, his engineering force, which is one of the most able corps of engineers and scientists ever gath cred together had been working for some time on the problem, both from the standpoint of wire and wireless trans mission. Transcontinental wire was publicly demon strated for the first time last Janu- ary, and the transcontinental wire
