The pack-saddle is fitted to the animal in a manner similar to that of the riding-saddle; it is so constructed that it can be placed one and one-half inches farther forward than the riding-saddle. If the pads are not square, draw the screws, unlace the pads from the skirts, then square and fit them to the animal by placing the canvas cincha immediately around the animal's girth, the front edge touching the breast-bone (cartilages of true ribs), the middle of the cincha being exactly in the middle of the lower edges of the pads; then screw the pads to the saddle-bars, keeping the cincha in place till the adjustment is made; then remove the cincha and replace the pads. Adjust the canvas cincha so as to be long enough to go nearly around the girth of the mule, over the saddle. Adjust the crupper by lengthening or shortening the lace-strings that attach it to the saddle, taking care not to make it too tight. TO SADDLE. Place the corona on the mule's back, about two to two and one half inches in front of where the pommel end of the saddle is to rest; place the folded saddle-blanket over the corona; take the saddle by both yokes and place it squarely in position, a little in rear of its proper place; place the crupper under the dock and gently move the saddle forward to position; pass the ring end of the canvas cincha over the saddle from left to right and under the belly; pass the latigo through the ring and tighten the cincha; when cinched, the ring end of the cincha should be above the lower edge of the near pad. CARGOES. The rations should be carefully put up in one-hundred-pound packs lashed solidly, and carried on the best pack-mules; each pack is plainly marked with its contents and weight. Salt, sugar, coffee, and beans are double-sacked, and lashed in one-hundred-pound packages. Bacon, in one-hundred-pound packages, is packed in from five to eight pounds of clean straw or hay, double-sacked and lashed firmly. The yeast-powder cases should be opened and hay or straw stuffed closely around the boxes to prevent shaking, and, with other articles, lashed into one-hundred-pound packages. Each cargo is in two side-packs of about one hundred to one hundred and twenty-five pounds each, and should match in size, shape, and weight as nearly as practicable, each side-pack having, as nearly as may be, the following proportions: width one half more than thickness, length nearly one half more than the width; e. g., 12 inches by 18 inches by 25 inches. All the salt, sugar, coffee, and beans should not be placed in one cargo. Ammunition should be in cargoes. Pads or cushions of hay 26 inches by 44 inches may be placed under the cincha to keep long and rough packs from the animal's hips and shoulders. TO LOAD CARGO.
