On this page Mr. Waud has illustrated for us the Army Telegraph. Of this important institution he says: “The army signal-telegraph has been so far perfected that in a few hours quite a large force can be in constant connection with head-quarters. This, while a battle is progressing, is a great convenience. The wire used is a copper one insulated, raised on light poles, made expressly for the purpose, on convenient trees, or trailed along fences. The wire and the instrument can be easily carried in a cart, which as it proceeds unwinds the wire, and, when a connection is made, becomes the telegraph-office. Where the cart can not go the men carry the drum of wire by hand. In the picture the cart has come to a halt, and the signal-men are hastening along—some with the drum, while others with crow-bars make the holes for the poles, upon which it is rapidly raised.
“The machine is a simple one, worked by a handle, which is passed around a dial-plate marked with numerals and the alphabet. By stopping at the necessary letters a message is easily spelled out upon the instrument at the other end of the line, which repeats by a pointer every move on the dial-plate. The whole thing is so simple that any man able to read and write can work it with facility.”
