When a halt is made the wagons are "corraled," as it is called, by bringing the two front ones near and parallel to each other. The two next are then driven up on the outside of these, with the front wheels of the former touching the rear wheels of the latter, the rear of the wagons turned out upon the circumference of the circle that is being formed, and so on until one half the circle is made, when the rear of the wagons are turned in to complete the circle. An opening of about twenty yards should be left between the last two wagons for animals to pass in and out of the corral, and this may be closed with two ropes stretched between the wagons. Such a corral forms an excellent and secure barricade against Indian attacks, and a good inclosure for cattle while they are being yoked; indeed, it is indispensable. STAMPEDES. Inclosures are made in the same manner for horses and mules, and, in case of an attempt to stampede them, they should be driven with all possible dispatch into the corral, where they will be perfectly secure. A "stampede" is more to be dreaded upon the plains than almost any disaster that can happen. It not unfrequently occurs that very many animals are irretrievably lost in this way, and the objects of an expedition thus defeated. The Indians are perfectly familiar with the habits and disposition of horses and mules, and with the most effectual methods of terrifying them. Previous to attempting a stampede, they provide themselves with rattles and other means for making frightful noises; thus prepared, they approach as near the herds as possible without being seen, and suddenly, with their horses at full speed, rush in among them, making the most hideous and unearthly screams and noises to terrify them, and drive them off before their astonished owners are able to rally and secure them. As soon as the animals are started the Indians divide their party, leaving a portion to hurry them off rapidly, while the rest linger some distance in the rear, to resist those who may pursue them.
