Mr. Rogers has devised a system by means ofwhich an ordinary tyj)ewriter may be used with an attach-ment that punches a paper tape. This tape is taken to thetelegraph office and run through a machine, whose opera-tion is synchronous with a machine at the receiving station,where the message is automatically printed, and deliveredto its destination in the form of a letter. This system gives. W^niJ n ROGERS S TYPEWRITER PREPARING TAPE. a speed of two hundred or more words a minute, which isas fast as a person can talk who desires to make himstlfunderstood. It has the added advantage of insurin<j; thecorrectness of the message. No repeating at double priceis required to insure accuracy. The message received mustbe the same as that originally written on the typewriter. This system is now actually in operation betweenWashington and Baltimore by the United States PostalPrinting Telegra])h Company, and seems destined to have IMPROVEMENTS IN TELEGRAPHV. 175 a wondrous growth. Though simple in its results, it re-quired twenty years of patient experimentation to bringit to perfection. In order to simj^lify transmiission the
