The driver's seat is a lock-box of three compartments, the two end ones being for spare revolvers and revolver-cartridges. The middle compartment is for the following articles, viz.: 1 wheel-grease can and spatula; 1 self-oiling axle-grease syringe; 1 hand-hammer; 1 wrench. On the rear of the wagon is carried a 25-gallon water-keg, fitted with bronze screw-bung and a spigot. Under the body of the wagon and above the reach and rockers are carried the spare double (1) and single (2) trees, and the following intrenching-tools, viz.: 2 long-handled shovels, 2 spades, 2 pickaxes, 2 axes. To the foot-board is attached a dash-board lamp, which when not in use may be carried in the compartment under the driver's seat. A boot to protect the driver is also provided. The wagon has a double cover; the first, of water-proof canvas, covering the top only; the second, of cotton duck, extends down the sides and far enough in rear to lace at the ends. A stout canvas cover in rear of the driver's seat prevents the load from being thrown to the front. No special place is provided for the two canvas water-buckets, which should be carried where they can readily be gotten at. To fill the axle with oil remove the screw-washers and fill the spindles by means of the axle-grease syringe. THE WATER-CART. Nothing of this kind is supplied; but battery commanders can readily improvise one for field marches and encampments and find it exceedingly useful. Obtain two good substantial wheels and an axle; attach shafts; build a suitable framework thereon to sustain a large barrel, which should have a faucet in the rear end and an opening for filling it on top. LIGHT-ARTILLERY HARNESS. The harness is made of black leather, black buckles, and without ornaments other than black leather rosettes. In connecting the principal parts of the harness and in attaching the horse to the limber hooks, hooking into rings or links only at the point where a depression is made in the ring or link, are used. =The Bridle= (_a_) is similar to the regulation cavalry bridle except that it has black buckles and black rosettes. The coupling-rein of the off horse can be lengthened or shortened as desired, and has a snap-hook for attaching the end to a ring on the saddle of the near horse. The lash end of the reins of the off horse passes through a roller on the pommel of his saddle and falls to the left, convenient to the driver's hand, so that by pulling it the horse is set back in his harness directly to the rear. =The Halter= is of leather, with leather halter-strap. =The Saddle.=
