[LB022043], Letter from Paul W Bossart to Southern Kansas Railway Co, James H Hill, April 20th, 1886

Editor's Notes

Your letter and diagram recd. I have just returned to the city which must account for delay in replying. I send you by todays mail copy of the "Electrical World" giving description of the phonoplex--which may aid you in judging of what value it will be to you. We do not claim that it can be made satisfactorily available on circuits of greater length than one hundred miles. I therefore would not recommend it for a through circuit from Lawrence to Cherryvale, but there would be no trouble in dividing the phonoplex circuit say half way between Lawrence and Cherryvale without dividing ["without dividing" is underlined] the request morse circuit. in other words you could retain your morse ckt as a through ckt from Lawrence to Wellington and work all stations direct with each other on the morse side, while the phonoplex, or second side, could be divided into three seciont, thus: [diagram] In this the first phonoplex [out?--written above the line] would extend from Lawrence to Girard, the 2d from Girard to Cherryvale, and the 3d from Cherryvale to Wellington and each would work independently of the other, while at the same time, and on the same wire you can work your regular Morse instruments though from Lawrence to Wellington, and to all intermediate stations. We do not interfere with your present Morse instruments. ## There would be no trouble whatever in working the circuit from Wellington to Kiowa with both sides at each station. ## It is not ["not" underlined] necessary to equip every station with instruments, they can be put in only when needed. We have just equipped a B&O Railroad line which has 19 stations all told, and we relieved the strain of business vastly on this line by putting in only three stations fully equipped with the duplex. Now, in your case if you duplexed from Lawrence to Girard, and from Wellington to Kiowa you may relieve the Morse side sufficiently to enable you to handle all other stations satisfactorily on the Morse side. It is possible to apply the phonoplex in about any form. You can work Morse the entire distance of your line and phonoplex any particular portion of it at the same time. ## If you think you do not fully understand the availability of it wire me again and I will try to explain further. Yours very truly
