The battery-officers' tents are on a line, at intervals of 5 yards, facing the interior flank, the captain's tent being nearest the guidon. The officers' mess-tent, of the batteries to the right of the battalion commander, is 10 yards in rear of the tent of the lieutenant on the flank. For batteries to the left of the battalion commander it is 10 yards in rear of the tent of the captain. Officers' kitchens are five yards in rear of mess-tents. In each battery: The picket-line is 15 yards in rear of the line of carriages. The tents for the enlisted men are 30 yards in rear of the picket-line, that of the first sergeant being on the interior and the guard-tent on the exterior flank. The cooks' tent is next to the guard-tent, the other tents being equally distributed along the line. The forage is 15 yards from the exterior flank, on the prolongation of the picket-line. The sinks are 90 yards from the forage, on the prolongation of the picket-line. The kitchens are on the line of the tents and 30 yards from the guard-tent. The tents of the battalion commander and staff are arranged, at intervals of 5 yards, on a line facing the interior flank. The mess-tent is on the flank nearest the front of the park, and the tents of the adjutant, quartermaster, and surgeon are on the other flank of the tent of the battalion commander. Non-commissioned staff-officers' and orderlies' tents are on a line 15 yards in rear of the staff-tents. The cook-tent is 5 yards to the rear of the outer flank of the mess-tent. The staff-wagons are on a line 15 yards in rear of the non-commissioned staff tents, the forage-and guard-tents being near either flank. Officers' sinks are on a line 60 yards in rear of the staff tents. The position of the kitchens may be varied, depending on the direction of the wind and lay of the ground. If the camp be established for more than a few days, the batteries will be parked in positions corresponding to the ones they occupy at battalion formation. BIVOUACS. The men bivouac at a convenient distance in rear of the park, each detachment opposite its section; the guard is on one flank and to the leeward; the cook-fires are near the guard. If necessary, the picket-line may be stretched through the hind wheels of the carriages of the third line, but whenever practicable the picket-line should be stretched along the ground or between trees or posts. A simple shelter may be formed by driving two forked sticks into the ground, with a pole resting in the forks, and branches laid resting on the pole, thick ends uppermost, at an angle of 45 degrees, and the screen completed with smaller branches; or a shelter of canvas or a blanket may be similarly made. Each man should strew his sleeping-place with dried leaves, etc., and place over it any articles such as bags, saddle-cloths, etc. A small hollow should be scraped in the ground just where the hip would rest.
