THE GALVANIC TELEGRAPH AT THE GREAT WESTERN RAILWAY
The space occupied by the case containing the machinery (which simply stands
upon a table, and can be removed at pleasure to any part of the room) is little more
than that required for a gentleman’s hat box. The telegraph is worked by merely
pressing small brass keys (similar to those of a keyed bugle), which acting (by means
of galvanic power) upon various hands placed upon a dial-slate at the other end of the
telegraphic line, as far as now opened, point not only to each letter of the alphabet (as
each key may be struck or pressed), but the numerals are indicated by the same
means, as well as the various points, from a comma to a colon, with notes of
admiration and interjection. There is likewise a cross (x) upon the dial which indicates
that when this key is struck a mistake has been made in some part of the sentence
telegraphed, and that an “erasure” is intended. A question—such, for instance, as the
following:--“How many passengers, started from Drayton by the ten o’clock train?”
and the answer could be transmitted from the terminus to Drayton and back in less
than two minutes. This was proved on Saturday se’nnight This mode of
communication is as far as the West Drayton station. There are wires (as may be
imagined) communicating with each end, thus far completed, passing through a
hollow iron tube, not more than an inch and a half in. diameter, which is fixed about
six inches above the ground, running parallel with the Railway, and about two or three
feet distant from it.
