Discussion on “a high-speed printing telegraph system” (Kinsley), Detroit, Mich., June 26, 1914. (see proceedings for June, 1914)

C. R. Underhill: Mr. Kinsley is certainly to be congratulated on the very ingenious device which he has brought out, and I must say that it is one of the most surprising forms of high-speed printing telegraph instruments which have come to my notice It seems, however, that it is necessary to use two wires and ground, which makes the line expensive, particularly since the machine is designed, I presume, for long-distance transmission, as that would be the service in which it would apparently have its greatest value, but the use of two wires may not be so detrimental as at first appears. Probably one great reason why the printing telegraph has not been adopted more in this country as compared with European countries is because in foreign countries the telegraph is used for letter writing. Abroad, I understand that it is customary to send a telegram instead of a letter, and for that reason the traffic is increased and the price is brought down.
