Abstract

[LETTERHEAD: Southern Kansas Railway Co.] Can report favorably on experiment of making a continuous phonoplex circuit from two separate Morse circuits (one running east-west, the other north-south); this company wants to know if it could use the phonoplex for working from the general offices in Ottawa on the main line to stations on one of the branches; began equiping line on Thursday and by Sat. had it working between two terminal phonoplex stations; since this is the first experiment jumping from east-west to north-south wire, I put in apparatus only at the two terminal stations and the junction to see if it would jump from one wire to the other; will begin to put in condensers tomorrow at way stations and put in intermediate phone stations (two), making a circuit of four stations; total length of circuit: 110 miles; diagram is enclosed.
