The vibration of the receiving-reed was 

 made to open and close a local circuit like a 

 common Morse relay and thus operate the 

 sounder. It is useless to try to send a message 

 if the sender and receiver are out of tune with 

 each other in this system. 



What is true in science is true in life. If 

 we are out of tune with our surroundings we 

 only beat the air, and our efforts are in vain. 

 We get no sympathetic response.
