 256 facsimile at the other. The present writer has experimented with the American Telautograph, and, so far as the experiments went, nothing could be more satisfactory. No knowledge of telegraphy whatever is required from the operator: he simply inscribes his message with a style on a piece of tissue-paper, and it reappears simultaneously at the other end of the wire. Nothing seems necessary but to furnish the catalogue desks with electrical transmitters (which occupy no great space) instead of inkstands, and to provide for the carrying of the wires out of the room. When the writer endeavoured to introduce electrical communication in 1894, he feared that this requisite would present difficulties, but was assured by experts that it really offered none. The ticket written by the reader might be retained by him as a memorandum: if it could be repeated in duplicate at the other end, one copy might be treated as now; the other, with any necessary correction, might be pasted at once into the register, saving all the time now occupied in registration.

It is of course perfectly possible that hitches and breakings down might at first occur from time to time, from the delicacy of the machine employed, or from other causes. The machines have not been properly tested, nor can they be, except by a continuous course of experiment. But whence this morbid fear of experiment? After Darwin's definition, the apprehension should surely be on the other side. A single machine, kept at work for a week, would be sufficient to test the principle.
