A Story Outline of Evolution 



Professor Samuel F. D. Morse, of New York, for inventing 

 the telegraph system in 1837, which has since been modified 

 and is now in such common use throughout the world. The 

 original Morse relay weighed 300 pounds, while that 

 employed today weighs about three pounds. The Morse 

 code is a system comprising an arbitrary alphabet and con- 

 sisting of the dot, the dash, the ordinary space, the letter 

 space, the word space and the sentence space. The duplex 

 system, the sending of two messages at the same time in 

 opposite directions, was perfected by J. B. Stearns in 1872 

 and the next year Thomas A. Edison perfected a method of 

 sending two messages simultaneously in the same direction 

 over the same wire. This was quickly followed by the quad- 

 ruples and multiplex systems. This method of instant com- 

 munication has extended to the stock quotation tickers, the 

 typewriting and autograph telegraph as well as photography 

 by electrical transmission. These lines of communication 

 have been extended to all parts of the civilized world and 

 the necessity for speedy communication between the con- 

 tinents has been solved by the submarine cables that bind 

 them together for this purpose. 



The telegraph, like the railroads, necessitated a system 

 consisting of a line of poles, means for producing the elec- 

 tric current, means for conducting the electric current, means 

 for controlling the duration of the current, and other fac- 

 tors as well as an understanding of the system and its code. 

 While this was a great public necessity and while its service 

 could be employed for hire by a private individual, yet the 

 complex system of modern civilization demanded a system 

 less complex in its nature and more practical in its use.
