I might go on at length, gi\ing one proljjeni alter another, by vva\' 

 of iliubtration, but I think enough has been said to give you a general 

 idea of the nature and great variety of the telephone engineering 

 problem in\ol\ ing, as it does, almost e\'ery phase of the mechanical, 

 electrical, and other arts. It is obviously necessary for the engineer 

 not only to consider the technical problems involved in each of these 

 matters, but to a greater extent it seems to me than almost any other 

 situation I have encountered, it is necessary for him to take into 

 account all of the related broad operating and business factors which 

 are naturally to be found in an industry of the magnitude of the Bell 

 System.
