Horses and mules will sometimes, especially in the night, become frightened and stampeded from very slight causes. A wolf or a deer passing through a herd will often alarm them, and cause them to break away in the most frantic manner. Upon one occasion in the Choctaw country, my entire herd of about two hundred horses and mules all stampeded in the night, and scattered over the country for many miles, and it was several days before I succeeded in collecting them together. The alarm occurred while the herders were walking among the animals, and without any perceptible cause. The foregoing facts go to show how important it is at all times to keep a vigilant guard over animals. In the vicinity of hostile Indians, where an attack may be anticipated, several good horses should be secured in such positions that they will continually be in readiness for an emergency of this kind. The herdsmen should have their horses in hand, saddled and bridled, and ready at an instant's notice to spring upon their backs and drive the herds into camp. As soon as it is discovered that the animals have taken fright, the herdsmen should use their utmost endeavors to turn them in the direction of the camp, and this can generally be accomplished by riding the bell mare in front of the herd, and gradually turning her toward it, and slackening her speed as the familiar objects about the camp come in sight. This usually tends to quiet their alarm. CHAPTER III. Repairing broken Wagons. Fording Rivers. Quicksand. Wagon Boats. Bull Boats. Crossing Packs. Swimming Animals. Marching with loose Horses.

The accidents most liable to happen to wagons on the plains arise from the great dryness of the atmosphere, and the consequent shrinkage and contraction of the wood-work in the wheels, the tires working loose, and the wheels, in passing over sidling ground, oftentimes falling down and breaking all the spokes where they enter the hub. It therefore becomes a matter of absolute necessity for the prairie traveler to devise some means of repairing such damages, or of guarding against them by the use of timely expedients. The wheels should be frequently and closely examined, and whenever a tire becomes at all loose it should at once be tightened with pieces of hoop-iron or wooden wedges driven by twos simultaneously from opposite sides. Another remedy for the same thing is to take off the wheels after encamping, sink them in water, and allow them to remain over night. This swells the wood, but is only temporary, requiring frequent repetition; and, after a time, if the wheels have not been made of thoroughly seasoned timber, it becomes necessary to reset the tires in order to guard against their destruction by falling to pieces and breaking the spokes.
