Abstract

"I have been working on the Reading circuit since Monday I found the Transmitters at both Reading offices very much out of adjustment. I also found a defective condenser in the depot office at Reading. After replacing this with one I found at the PRR office on Walnut St Phila the Phone worked fairly well between Phila and Reading but we could hardly hear Pottsville at Reading. I came to Pottsville this mornign and everything OK except one of the coils in the Phone entirely dead. I also replaced this with a Phone from the PRR office. Still the circuit did not come up as it should. Mr Adams left for Reading at 215 PM. About 4 PM the gentlemen here informed me that they had an idle broken wire and we changed the wire between Reading and Pottsville. This change imprved the Phone 100 per cent. Also cleared the Morse whih they complain works. Shocking. I called Mr Adams to the Phone at Reading and asked him if he was convinced that the trouble was not in the system but in the wire. He did not seem to think much of the question and would not be convinced. He wanted to know if I acknowledged the Phone would not work on the old wire. Of course I told him no sir but I thought it reasonable to suppose that the trouble was on his wire. He claims that the wire works OK with the Phone off. ### We'll say that it does, this demonstrates the fact that the [unclear] wire has not enough of battery to overcome the entire resistance the 4 phones, cords and the two permanetn magnest add to [unclear] it wire. I have told him this but e claims that there is enough. The wire they have it on is a very old one and requires more battery than a new one. I think it has been up about 20 years. It is a 1W9 iron wire. ### Tonight I have the Phone circuit working fairly well but it is a question if he will be satisfied with it tomorrow. I neglected to say that we increased the battery 2 cells at Phila and one cell at each of the other offices. ### By changing the wire between Pottersville and Reading 35 miles removes the trouble on both circuits but he declines to do this. ### From what I can learn here the wire they have it on now is the only one that ever gave them any trouble. ### I hope to satisfy him tomorrow." Yours very truly, W.S. Logue [Postscript: "I hear that they allow one volt for each 50 ohms of resistance. Guessing at the resistance. The [unclear] allow one volt for each 30 ohms and do this by measurement. Mr A claims there is no relay between here & Reading but it looks queer."]
