Threefold Co-operation 



Every telephone connection requires 

 co-operation. The slightest inattention 

 or indifference on the part of the per- 

 son who calls, or the company that 

 makes the connection, or the person 

 who is called results in a correspond- 

 ing deficiency in service. Each is 

 equally responsible for the success of 

 the service. 



Not only is it to the advantage of the 

 individual himself to use the telephone 

 efficiently, but his conservation of the 

 advantages of these national lines of 

 speech benefits all telephone users. 



Accuracy in calling, promptness in 



answering, clear and deliberate talk- 

 ing, courtesy and patience on the part 

 of both user and operator are essen- 

 tials of service, and must be mutual 

 for good service. 



Efficient telephone operation is 

 vital to the war work of this country. 

 The army, the navy and the myriad 

 industries contributing supplies de- 

 pend on the telephone. It must be 

 ready for instant and universal use. 

 The millions of telephone users are 

 inseparable parts of the Bell System, 

 and all should patriotically contribute 

 to the success of the service.
