The signals of movement are so short, that the words of execution may nearly coincide with them.

These signals for quick movement, may in regular exercise be given by a person who at the instant of giving them is stationary; but if he leads the body in motion, it is evident that in the gallop, the charge, and the halt, the voice and the eye, can only determine, and regulate.

23. Turn out skirmishers. This signal is made by the commander of the whole, if the whole is concerned, otherwise by the commander of such part only as is to execute; if one, or two squadrons only, the voice will suffice. It may be a signal for pursuers after a charge.

24. Call in skirmishers. This signal is made by the commander of the whole, and repeated by the commander of the detachments; is for the skirmishers to join their detachments; or it may originally come from the commander of the detachments. On the signal to rally, the whole join the bodies they were detached from.

25. Skirmishers cease firing. This signal is made by the commander of the whole, and repeated (or originally made) by the commander of the supporting detachments, from which the skirmishers are advanced.

Bugle Horn Soundings, are different calls which are made by the bugle horn for duty and exercise. The following constitute the principal ones. See Am. Mil. Lib.

1st. For duty.
 1.Revillé.- These soundings are different in their notes fromthose of the trumpet, but may be used under the same circumstances.
 2.Rouse, or turn out.
 3.Dinner call.
 4.Setting the watch.
2d. For exercise.
 5.March. -These soundings exactly the same as those of the trumpet,in the place of which the bugle horn may be occasionally substituted.
 6.Trot.
 7.Gallop.
 8.Charge.
 9.Halt.
10.Retreat.
11.Rally.
12.Turn out skirmishers.
13.Skirmishers cease firing.
14.Call in skirmishers.

These signals, of the trumpet, and bugle horn, are meant in aid of the voice, but are by no means to be substituted for, or prevent the ordered words of execution.

The trumpet is always to be considered as the principal military instrument for these soundings, and particularly belongs to the line; the bugle horn to riflemen and detached parties.
