Takes an awful time to get these Pennsylvania circuits in running order. Write me more frequently re what you are doing. Royalties being eaten up by expense which we put in starting circuits and nursing them. Lehigh Valley Railway circuits and others are self sustaining, and I cannot see why Penn R. R. should not have men capable of maintaining the service, as found on other and less important railways. You spend too much time with Division Operators and not sufficient time with higher officials. If the time taken to convince three or four Div. Operators were employed in convincing one General Superintendent that the Phonoplex can be worked, is being worked on several lines and is a useful addition to their Telegraph System, it would do us more good. # Received your letter re long carbons. Can get long carbons if they are in the market, but cannot go to expense of having them made for our work. Do not see why necessary to fill a cell so full of liquid as to eat away connections.
