SIGNALS

Signals are made by firing artillery, and displaying colours, lanthorns, or fire-works: and these are combined by multiplication and repetition. Thus, like the words of a language, they become arbitrary expressions, to which we have previously annexed particular ideas: and hence they are the general sources of intelligence throughout a naval armament, &c. See ADMIRAL and ENGAGEMENT.

Signals ought to be distinct, with simplicity. They are simple, when every instruction is expressed by a particular token, in order to avoid any mistakes arising from the double purport of one signal. They are distinct, when issued without precipitation; when sufficient time is allowed to observe and obey them; and when they are exposed in a conspicuous place, so as to be readily percieved at a distance.

All signals may be reduced into three different kinds, viz. Those which are made by the sound of particular instruments, as the trumpet, horn, or fife; to which may be added, striking the bell, or beating the drum. Those which are made by displaying pendents, ensigns, and flags of different colours; or by lowering or altering the position of the sails: And, finally, those which are executed by rockets of different kinds; by firing cannon, or small arms; by artificial fire-works; and by lanthorns.

Firing of great guns will serve equally in the day or night, or in a fog; to make or confirm signals; or to raise the attention of the hearers to a future order. This method, however, is attended with some inconveniencies, and should not be used indiscriminately. Too great a repetition of the cannon is apt to introduce mistakes and confusion, as well as to discover the track of the squadron. The report and flight of the rockets is liable to the same objection, when at a short distance from the enemy.

It is then, by the combination of signals previously known, that the admiral conveys orders to his fleet; every squadron, every division, and every ship of which has its particular signal. The instruction may therefore occasionally be given to the whole fleet, or to any of its squadrons; to any division of those squadrons, or to any ship of those divisions.

Hence the signal of command may at the same time be displayed for three divisions, and for three ships of each division; or for three ships in each squadron, and for only nine ships in the whole fleet. For, the general signal of the fleet being shewn, if a particular pendent be also thrown out from some remarkable place on the same mast with the general signal, it will communicate intelligence to nine ships that wear the same pendent.
