OTTAWA MAP SHOWING VOICE VOYAGES MADE IY THE NATIONAL GEOGRAI'1IIC SOCIETY' FROM WASHINGTON TO PITTSBURGII, CHICAGO, OMAIA, DENVER, SALT LAKE CITY, SAN FRANCISCO, PORTLAND, SEATTLE, EL PASO, OTTAWA, JACKSONVILLE, AND INTERMEDIATE POINTS through the forty years that have passed since Alexander Graham Bell first solved the problem of sound transmission by electricity. The telephone paid tribute to Dr. Bell, its father, by transmitting with equal fidelity the sound of music, the roar of breakers, and the intonations of the hu man voice. It paid its tribute to Presi dent Vail by proving that it indeed had grown to be a national institution in its geography, in its use, and in its possibili ties. It paid its tribute to the great engi neering staff, headed by John J. Carty, by demonstrating that it had, through them, ceased longer to be dependent on wires, but could now make the IIertzian waves its messengers-messengers which can travel eight times around the earth between the beats of the human heart. The big banquet hall of the New Wil lard is nearly a city block long and per haps sixty feet wide. Eight hundred people were seated around the tables of the huge gridiron, each with a telephone receiver at his elbow. At the one end of the great hall was a large map, with electric lights marking every junction station on the transcontinental voice highway, from Florida to Puget Sound and from Ottawa, Canada, to El Paso, Texas. VOICE VOYAGES TO SEATTLE After the courses had been served, the chief of the engineering staff of the American Telephone and Telegraph Company, Mr. John J. Carty, announced that the assembled guests would take a voice voyage to Seattle, Washington. Eight hundred receivers went to eight hundred wondering ears and the trans continental roll-call began. "Hello, Washington, D. C.," said Mr. Carty. "Ilello, M\r. Cartv: this is Washing ton; Truesdale speaking,' came the an swer. And the bulb indicating the Na tion's Capital on the electric map grew bright.
