The inventors of automatic systems maintain thatall this is feasible and should have been carried outlong ago; while, on the other hand, the managers oflarge telegraph systems, although permitting theirwires to be used for such experimental work, assertthat the practical difficulties are too serious to be over-come, and that the key and the sounder associatedwith the Morse alphabet remain to-day the necessaryfoimdation of the commercial telegraphic art. Withone of the modern machine telegraphs, the ingeniousBuckingham system, over one and a half million mes-sages have been transmitted, and a record has beenmade of 2,429 words between New York and Chicagoin slightly less than twenty-four minutes.
