Science and Progress 549 



Samuel F.B. Morse gave to the world the telegraph, which marked 

 the greatest single stride in the advancement of communication. 

 It shortened the time required for a message to pass between far 

 distant points from days or hours to minutes or seconds, and 

 opened a new era in business. In 1858, Cyrus W. Field, by 

 laying the first Atlantic cable, extended the principle of the tele- 

 graph to communication with foreign lands. This in turn pro- 

 moted international business, and facilitated the gathering of 

 news. 



The invention of the telephone in 1876 by Alexander Graham 

 Bell led to a new means of communication, simple in its operation, 

 and easily installed in any home or office. Probably nothing has 

 done more to tie communities together and to increase business 

 than the telephone. We need only notice the extent of its use in 

 our ewn neighborhood to realize its tremendous importance in our 

 modern life. 



Late in the 19th century, Marconi gave to the world wireless 

 communication, or radio. Here again was a distinct advance, for 

 messages could be sent by waves in the ether in any direction, 

 without wires. At first, wireless messages were sent by telegraph 

 code. Scientists, today, however, have so perfected radio trans- 

 mission and reception that music, the human voice, and even pic- 

 tures may be sent great distances and reproduced accurately 

 wherever there are proper instruments for their reception. 



Modern radio is a splendid example of what Science can do. 

 Already it enables ships to keep in constant communication with 

 the shore and with each other, summoning help when disaster 

 threatens, or receiving warnings of approaching storms, icebergs 

 and other perils. Through the broadcasting of concerts, lectures, 

 news bulletins, and athletic contests, it furnishes entertainment 

 and instruction for many millions of people. Through weather 

 forecasts it serves the growers and shippers of fruit. Yet radio 

 is seemingly still in early stages of development and Science will 

 undoubtedly make it even more wonderful and useful to us as time 

 goes on. 



Science and Building. Wonderful structures were built in 

 past ages. Their construction, however, was very slow with
