|Boy's Manual of Seamanship and Gunnery|
The Semaphores, or Signal Stations established on the coast of France, have, wherever practicable, the means of intercommunication by Electro-Telegraphic Wires with each other, and with the chief Metropolitan, Provincial, and Foreign Telegraph Stations.
By the method hereafter described, passing vessels will be able to exchange communication with these Semaphores, and their messages will be received, and, if required, forwarded to their destination according to the established Tariff of Rates.
Although at present there are no similar facilities of communication placed at the Service of Shipping frequenting the coast of the United Kingdom, it is believed that should Signal Stations be hereafter established, the French system affords the simplest means of Signalling by Semaphore between the shore and Ships in the offing, at a distance whence the colours of Flags would not be distinguishable.
At a moderate distance the Signal Flags of the Code can, of course, be used by both Ships and Signal Stations, but the Distant Signals should on all occasions be employed by Ships when it is found that the Code Flags cannot be made out.
The Semaphores are furnished with three Arms. When at rest the Arms are not visible. When at work the position of the Arms in the three directions, indicated in the Plate (page 229), represents respectively the three Symbols used in the Distant Signal Code.
The Semaphore Signals will consequently be, always read off as Distant Signals, the position or direction of the Arms indicating respectively the Pendant, the Ball, or the Flag.
ADAPTATION OF THE FRENCH SEMAPHORIC SYSTEM TO THE COMMERCIAL CODE FOR MAKING DISTANT SIGNALS
N.B. The disc at the top of the mast remains in the position indicated below whilst signals are being made by this code.

APPLIED TO THE CHARACTERS OF THE SIGNAL FLAGS IN THE VOCABULARY
ALPHABET FOR SEMAPHORE SIGNALS
The Symbols to be employed are:
Two Square Flags, or Pieces of Cloth of any colour.
2. Two Whelfs, or Strips of Cloth of any colour.
3. Two Balls, Bundles, or Hats of any colour.
By means of the above Symbols, all the Signals of the Distant Signal Code may be made, as shown above. Handkerchiefs, Hats, Buckets, or Baskets, may be used in making these Signals ; and, if no Mast, Pole, or Spar is handy, these Signals can be made by holding the Hat, Bundle, or other Symbol at arm's length. The Signals will be made from right to left, and be read off from left to right.
NOTE.-It is necessary, however, in using the proper means to attract attention, to avoid those which may occasion confusion.
