By Night.

It is impossible to lay down any fixed, principles on this subject; but the general rules are, to advance the Picquet at least two or three English miles in front of the main body: to place it behind a bridge, ravine, wood, or bog through which the road passes, in order to be enabled to make a stand immediately on being attacked, and to place Videttes in front and flanks. Small Patrols of two or three men in front, and flanks at half an hour's interval, and constantly kept in motion, will give perfect security, particularly if one of the men sometimes dismounts, and listens with his ear on the ground: he will hear the march of troops at a great distance. This precaution is indispensable in stormy weather. Upon coming by night to a new spot, particularly in a mountainous or woody country, small Patrols must be pushed forward immediately in all the roads, &c., to secure in the first instance the placing of Videttes, &c., &c.

If the enemy is near, no fire is to be lighted, and the spot where the Picquet stands should be changed very often; one-half of the Picquet should be mounted, the other stand with the bridles in their hands.

SECTION IV.

RELIEVING ANOTHER PICQUET.

Great part of what is said in sections I. and II. is likewise to be applied here. As soon as the Officer is arrived at the Picquet that is to be relieved, he forms at its left flank, or behind it, as the nature of the ground requires, draws out a non-commissioned officer, and as many Videttes as he has to relieve, (the remainder dismounts,) and proceeds with the Officer commanding the old Picquet and his own non-commissioned Officer to relieve the Videttes. The Officers should be very particular in delivering the detail of their duties, and the following is to be observed on such occasions.

1. All written orders or instructions must be delivered, and the verbal orders written down and signed by the Officer who is relieved.

2. The outlines of the sketch belonging to the Officer commanding the old Picquet are to be copied and filled up afterwards—
