Gun and Wheels.—The gunner removes the tangent-sight, placing it in the haversack, and puts on the breech-cover.

No. 1 throws back the right cap-square and puts on the muzzle-cover and grasps gun by manœuvring-handle.

No. 2 throws back the left cap-square and grasps end of breech-block.

Fig. 10.

No. 4 leads the gun-mule to the gun and places him three yards to the rear of the trail, facing to the rear.

The gunner, grasping the muzzle, commands "Lift," and all lift the gun from the carriage and place it in its bearings, breech in front, sight down.

The gunner, assisted by Nos. 1 and 2, puts cargo-cincha over gun, trunnions passing through slots, edge of cincha nearest to slots in front; cinches to belly-cincha; and then puts gun-pad on breech of gun.

Nos. 1 and 2 on their respective sides then lift the axle while the gunner removes the wheels and replaces linch-pins and washers; Nos. 1 and 2 fasten them together with wheel-strap, dish of wheels inside, and place them astride of gun, hubs between wheel-pads on cargo-cincha, lower them to their proper position, and suspend them with the hub-strap which passes around the hubs and over top of gun. On most animals the best position for wheels is to have the distance from bottom of hub, measured over top of saddle, 36 inches.
