Every year thousands of them are caught in this section by the Assiniboin, and at the time we are writing there are three parks in operation a short distance from this, all doing a good business. When a camp of 30 to 60 lodges find themselves deficient in guns and horses they move to a suitable place to build a park (pl. 69), and there wait the approach of buffalo toward it. Most streams have high bluffs on each side and a valley between. They therefore pitch their camp in the valley opposite and near a gap of perpendicular descent through the hills; a high level plain being beyond the bluffs. They cut timber and plant strong posts in the ground nearly in a circular form and fill up the openings between with large logs, rocks, bushes, and everything that will in any way add to its strength, inclosing an area of nearly an acre of ground. This enclosure is run up the sides of the hill to the gap or entrance _C_, though neither it nor the camp is visible from the place beyond. The whole is planned and managed by the master of the park, some divining man of known repute, who is believed to have the power of making the buffalo come into it by his enchantments. On the plains beyond, and commencing where the wood mark leaves off, are thrown up piles of earth, about 3 feet high and large enough to conceal a man lying behind them, which are about 18 paces apart and extend in angles to the distance of a quarter to half a mile in proportion as there are people to man them. When these arrangements are completed, four fast running young men are selected by the manager whose duty it is to scour the country every day or two, making a circuit of about 20 miles in discovery of buffalo, and report to headquarters. The master in the meantime commences his magic arts as follows: A flagstaff or pole is planted in the center of the park, to the top of which is attached a yard or two of scarlet cloth, some tobacco, and a cow’s horn. This is a sacrifice to the Wind. At the foot of the same are placed two or three buffalo Heads which are painted red, decked out in feathers, and new kettles with scarlet cloth and other things placed before them. These are given to the Buffalo Spirits.
