3. Each man is allowed 2 feet in the ranks of the battalion, and 3 feet in the squadron: thence the front of a battalion of 500 men, formed 3 deep, will be 324 feet; and the front of a squadron of 150 men, formed 2 deep, will be 225 feet. 4. The depth of the _camp_ when the army is encamped in 3 lines, is at least 2750 feet; that is, 750 feet for the depth of each line, and 250 feet for the space between each of those lines. 5. The park of artillery should always be placed on a dry rising ground, if any such situation offers; either in the centre of the front line, or in the rear of the second line; with all the train horses encamped in the rear of the park. 6. The bread-waggons should be stationed in the rear of the _camp_, and as near as possible to the centre, that the distribution of the bread may be rendered easy. 7. When the commander in chief encamps, it is generally in the centre of the army; and the town or village chosen for his residence is called head quarters. 8. That general is inexcusable, who, for his own personal accommodation, makes choice of quarters that are not properly secured, or at too great a distance to have an easy communication with the _camp_. 9. If the ground permits, the troops should be encamped as near to good water as possible. 10. When there are hussars or rifle corps, they are generally posted near the head quarters, or in the front of the army. 11. The ground taken up by the encampment of an army, should be equally distributed, and, if possible, in a straight line; for then the whole will have more room: for a crooked line, and an inequality of disposition, afford a very unpleasing view both of the camp, and of the troops when they are under arms. 12. Cleanliness is essentially necessary to the health of a _camp_, especially when it is to remain for any length of time. To maintain this, the privies should be often filled up, and others opened; at least every 6 days. The offal of cattle, and the carcasses of dead horses, should be buried very deep: and all kinds of corrupt effluvia, that may infect the air and produce epidemical disorders, should be constantly removed. _Choice of_ CAMPS. 1. At the beginning of a campaign, when the enemy is at too great a distance to occasion any alarm, all situations for _camps_ that are healthy are good, provided the troops have room, and are within reach of water, wood, and provisions. More ground should be allowed to the troops in _camps_ of duration, than in temporary ones. 2. _Camps_ should be situated as near as possible to navigable rivers, to facilitate the conveyance of all manner of supplies; for convenience and safety are the principal objects for _camps_. 3. A _camp_ should never be placed too near heights, from whence the enemy may overlook it; nor too near woods, from whence the enemy may surprise it. If there are eminences, not commanded by others, they should be taken into the _camp_; and when that cannot be done, they should be fortified.
