In turning out pack animals to graze, it is well either to keep the lariat ropes upon them with the ends trailing upon the ground, or to hopple them, as no corral can be made into which they may be driven in order to catch them. A very good way to catch an animal without driving him into an inclosure is for two men to take a long rope and stretch it out at the height of the animal's neck; some men then drive him slowly up against it, when one of the men with the rope runs around behind the animal and back to the front again, thus taking a turn with the rope around his neck and holding him secure. To prevent an animal from kicking, take a forked stick and make the forked part fast to the bridle-bit, bringing the two ends above the head and securing them there, leaving the part of the stick below the fork of sufficient length to reach near the ground when the animal's head is in its natural position. He can not kick up unless he lowers his head, and the stick effectually prevents that. Tether-ropes should be so attached to the neck of the animal as not to slip and choke him, and the picket-pins never be left on the ropes except when in the ground, as, in the event of a stampede, they are very likely to swing around and injure the animals. Many experienced travelers were formerly in the habit of securing their animals with a strap or iron ring fastened around the fetlock of one fore foot, and this attached to the tether-rope. This method holds the animal very securely to the picket-pin, but when the rope is first put on, and before he becomes accustomed to it, he is liable to throw himself down and get hurt; so that I think the plan of tethering by the neck or halter is the safest, and, so far as I have observed, is now universally practiced. The mountaineers and Indians seldom tether their animals, but prefer the plan of hoppling, as this gives them more latitude for ranging and selecting the choicest grass. Two methods of hoppling are practiced among the Indians and hunters of the West: one with a strap about two feet long buckling around the fore legs above the fetlock joints; the other is what they term the "_side hopple_" which is made by buckling a strap around a front and rear leg upon the same side. In both cases care should be taken not to buckle the strap so tight as to chafe the legs. The latter plan is the best, because the animal, side-hoppled, is able to go but little faster than a walk, while the front hopple permits him, after a little practice, to gallop off at considerable speed. If the hopples are made of iron connected with chains, like handcuffs, with locks and keys, it will be impossible for the Indians, without files, to cut them; but the parts that come in contact with the legs should be covered with soft leather.
