Its form must depend on its situation. Ten feet are usually allowed in front for one carriage and its interval, and near 50 feet from the hind wheels of the front row to the fore wheels of the second; this interval should allow sufficient room for putting the horses to the carriages, and for a free passage along the line. In parks not on immediate service, it is customary to arrange the guns with their muzzles to the front; but where the guns are likely to be wanted at a short notice, appearances must not be studied, and the gun carriages must be parked with their shafts to the front, ready to receive horses to them. A quarter-guard is placed in front of the park, and the noncommissioned officers and gunners’ tents on the flanks, at about 20 paces distance and 40 paces to the rear the subaltern officers; at 10 more to the rear the captains, and 10 more the commanding officer. The mess tent is 15 in the rear of the officers. At a convenient distance in the rear of the whole, are the horses, picketed in one or more lines, with the drivers on their flanks. The horses are sometimes picketed in lines perpendicular to the front, and on the flanks of the carriages, between the men and the carriages. See the word _Camp_, and _Artillery in the Field_. _PENDULUM_—Pendulums for military purposes are best made with a musquet ball, and a piece of silk, or other small line. Their length must be measured from the centre of the ball to the end of the loop on which they are to swing. In a cylinder, or other uniform prism or rod, the centre of oscillation, (from whence they must be measured,) is at the distance of ⅓ from the bottom, or ⅔ below the centre of motion.
