achievements and development in America have so greatly exceeded 

 those of other countries. 



The original personnel of these laboratories consisted of but 

 two men, Alexander Graham Bell, the inventor of the telephone, 

 and Thomas A. Watson, his associate, who constructed under 

 Bell's direction the first telephone, and who heard through it from 

 the lips of Bell himself the first words transmitted electrically. 



At the present time the personnel, which includes graduates of a 

 hundred American colleges and universities, consists of thirteen 

 hundred scientists and engineers who devote their time exclusively 

 to research and development in the telephone art. 



On the table before you is one of the first products of these 

 laboratories. It is a model of the first telephone by means of which 

 Bell was able to communicate with Watson, but over a distance not 

 greater than across this room. Starting with such feeble instru- 

 ments, the scientific personnel of these laboratories the successors 

 of Bell and Watson by persistent study, incessant experimenta- 

 tion and the expenditure of immense sums of money, have created 

 an entire new art: inventing, developing and perfecting, making 

 improvements great and small in telephone, transmitter, line, 

 cable, switchboard, and every other piece of apparatus and plant 

 required for the transmission of speech. 



As a result of this unceasing organized effort and these cumula- 

 tive improvements in the art, Dr. Bell was enabled to talk once 

 more to Mr. Watson through this original historic instrument, 

 although they were thousands of miles apart, the one at San 

 Francisco and the other at New York. 



These two original telephones have increased marvelously in 

 numbers and efficiency, and the first telephone line of a hundred 

 feet in length has been expanded into a network covering the 

 continent, until the telephone system of the United States alone 

 comprehends thirty-one million miles of wire and thirteen million 

 telephone stations connecting a hundred million people located 

 everywhere throughout the country. 



Pressing on to achieve still greater distances, the staff of these 

 laboratories, by utilizing many scientific discoveries, have trans- 

 mitted the human voice, without the use of wires, from Washington 

 across the North American continent to San Francisco and even 

 far out into the Pacific Ocean to the Hawaiian Islands, where 

 words spoken at Washington were plainly heard. By this same 

 apparatus and by these same scientists intelligible speech was for
