THIRD OR FOURTH ANIMAL. (See Fig. 12.) =Ammunition.=--Each animal carries four ammunition boxes, each containing 18 rounds of ammunition: total rounds 72. Nine cartridges and ten primers are packed in each end of each box. The gunner and Nos. 1, 2, and 3 put the ammunition-boxes in position, the two top ones first, simultaneously, and then the two bottom ones in the same way. No. 3 then returns to his mule, which he had turned over to No. 4; and Nos. 1 and 2 secure the boxes in position by the straps fastened to the clips, and the gunner cinches them securely with the cargo-cincha. He then passes a lashing-rope around the iron handles on the ends of the boxes and over the pack, and the whole is securely fastened in place. [Illustration: FIG. 12.] TO HARNESS FOR DRAUGHT. Nos. 3 and 4 place harness on their mules, and lead them into position for hitching, and when the pole has been adjusted complete hitching in front of mules. Nos. 1 and 2 lift trail and the gunner attaches the pole. Nos. 1 and 2 hitch traces.
