- Editor's Notes
- "The demand for 10 C.P. lamps is marked in this country; for example, -the Des Moines Station is running with 10 C.P. lamps on the meter basis, and they are very much puzzled as to what to do with the 'NEW' lamp. The 10 C.P. lamp gives satisfaction to their consumers, and they do not feel as if they cared to make any change. Kindly read carefully the latter part of Prof. Columbo's letter and let me know what reply to make to him. ### You will note Mr. Lie's remarks about the 'alternate currents', this is in answer to a series of questions which I sent to him. ### I saw a gentleman from Denver, who has the financial charge of the station, and he said, that machines had been coupled in multiple arc there to run some heavy lighting for special illumination, and that as far as he knew they worked successfully. ### Fro the general working of the stations the machines are run separate dividing up the circuits among them. He expressed himself as thoroughly satisified with the working of the station, and the financial results obtained. He said, that their system was an underground one, and that they only had trouble with their conductors at the junction point, due to moisture getting into the boxes. He also stated that they had only lost two of their convertors by crossing." Very truly yours, Francis R. Upton [Marginalia: "Upton- Make a 10 candle cut + run 100 through + will test them I don't think there will be any trouble." E.] NEW LAMP
