Nearing a crest and in sight of game
Such a rig prevents the breeching from riding up or dropping down; it gives the horse all his wind going up hill, but holds firmly going down; when one part loosens, the other tightens; and the saddle cinch, except to keep the saddle from turning, is practically useless and can be left comparatively loose. I cannot too strongly recommend you, both for your horse's comfort and your own, to adopt this rigging.
Kyacks
The kyacks, as I have said, are two sacks to be slung one on each side of the horse. They are provided with loops by which to hang them over the sawbucks of the saddle, and a long strap passes from the outside of one across the saddle to a buckle on the outside of the other.
Undoubtedly the best are those made of rawhide. They weigh very little, will stand all sorts of hard usage, hold the pack rope well, are so stiff that they well protect the contents, and are so hard that miscellaneous sharp-cornered utensils may be packed in them without fear of injury either to them or the animal. They are made by lacing wet hides, hair out, neatly and squarely over one of the wooden boxes built to pack two five gallon oil cans. A round hardwood stick is sewn along the top on one side—to this the sling straps are to be attached. After the hide has dried hard, the wooden box is removed.
Only one possible objection can be urged against rawhide kyacks; if you are traveling much by railroad, they are exceedingly awkward to ship. For that purpose they are better made of canvas.
Canvas Kyacks
Lash Ropes
Many canvas kyacks are on the market, and most of them are worthless. It is astonishing how many knocks they are called on to receive and how soon the abrasion of rocks and trees will begin to wear them through. Avoid those made of light material. Avoid also those made in imitation of the rawhide with a stick along the top of one side to take the sling straps. In no time the ends of that stick will punch through. The best sort are constructed of OO canvas. The top is made of a half-inch rope sewn firmly to the hem all around. The sling straps are long, and riveted firmly. The ends are reinforced with leather. Such kyacks will give you good service and last you a long time. When you wish to express them, you pack your saddle and saddle blankets in one, telescope the other over it, and tie up the bundle with the lash rope. The lash rope is important, for you will have to handle it much, and a three months' trip with a poor one would lose you your immortal soul. Most articles on the subject advise thirty-three feet. That is long enough for the diamond hitch and for other hitches with a very small top pack, but it will not do for many valuable hitches on a bulky pack. Forty feet is nearer the ticket. The best is a manila half inch or five-eighth inch. If you boil it before starting out, you will find it soft to handle. The boiling does not impair its strength. Parenthetically: do not become over-enthusiastic and boil your riata, or you will make it aggravatingly kinky. Cotton rope is all right, but apt to be stiff. I once used a linen rope; it proved to be soft, strong, and held well, but I have never been able to find another.
