According to the orders of their leader they proceed slowly, scatter in different directions for miles around, lie about on the tops of the hills covered with their wolf skins, or headdresses made of bunches of wild sage, examining the country in every direction for hours before they move. If nothing is seen they signal to each other the result by imitating the howling of wolves, the barking of foxes, or the hooting of owls, as the signals agreed upon require. Assembling in some hollow, they compare notes, receive new directions, and proceeding a few miles, separate again and reconnoiter as before. They now shoot very seldom, and only when meat is absolutely wanted, and the wind blows in a direction to carry the report away from their enemies, or toward that part of the country already explored. By observing the movements of crows and wolves, in which direction they travel, where they stop and light, they will find out the carcass of some animal killed by the hunters of the camp. The state of its decay, tracks, and other signs around will determine the probable direction of their enemies, and they steer for that point. When advanced thus far—that is, to know they are in the vicinity of a camp—the real science of their manner of warfare exhibits itself. Night marches commence, and separating as before about daylight they occupy the hills, lying motionless all day, watching in every direction some signs of their enemies. They are placed so as to be within call of each other, and the signals for different discoveries being agreed upon by imitating the howling of wolves, etc., as has been stated, they can communicate with each other all the time without rising to their feet. They never expose their persons to view on a hill. If necessary to assemble they crawl down and meet in some ravine well covered with thick bushes. They now never shoot, make no fire, eat nothing, keep very quiet, and travel in the night. Of course, by these measures they must soon perceive some one belonging to the camp, and by observing his direction will find where it is. Having discovered the camp, the last rendezvous takes place prior to the attempt upon the horses, and here several things are determined—a place is agreed upon where they will all assemble after the attack, a direction for the return chosen in case of separation, smoking, and invoking the different fetishes are performed, and general directions given by their leader as to the manner of approaching the camp.
