A Story Outline of Evolution 



from President Roosevelt to King Edward VII of England 

 and a new era was ushered in upon the stage of human 

 action in the science of communication. If we shall suppose 

 that we are on a vessel in the middle of the ocean and that 

 the vessel is disabled and sinking or is on fire; that an 

 SOS call is sent out and an answer is received that aid is 

 coming, or perhaps we have taken to the lifeboats after the 

 assurance of aid is received, then and only then, can we fully 

 appreciate what wireless telegraphy means to civilization. 

 Before the development of this thought, many thousands of 

 persons whose lives to them were as valued as ours are to 

 us, were lost in the depths of the ocean without a trace. 



But again the greedy searchers were not satisfied and 

 they continued to work. They reasoned among themselves 

 that since it is possible that signals may be carried on the 

 radiation and reception of guided electro-magnetic waves, 

 and since the signals represent sounds which are an arbitrary 

 alphabet, why is it not possible to carry the articulate sounds 

 of the human voice in the same or a similar manner? 



The next link to be added to the chain of progress in the 

 science of electrical communication was that of the radio, 

 the most mysterious and far-reaching means of communica- 

 tion known to civilization. It is of such recent origin that 

 no description of Its parts is here necessary. Its hidden 

 secret was found In a vacuum tube and like so many of 

 Nature's secrets, this was discovered largely by chance. It 

 is one of the greatest means of education ever devised. 

 Scientists tell us that not a word we speak Is lost and that 

 every audible sound Is carried on the wings of the ether 

 waves to the uttermost parts of the earth. They may go,
