Now it must be remembered that in early days the hunting weapons of this people consisted only of stone-pointed arrows, and with such armament the capture of game of the larger sorts must have been a matter of some uncertainty. To drive a rude stone-headed arrow through the tough hide and into the vitals of the buffalo, could not have been—even under the most favorable circumstances—other than a difficult matter; and although we may assume that, in those days, it was easy to steal up to within a few yards of the unsuspicious animals, we can readily conceive that many arrows must have been shot without effect, for one that brought down the game.
Certain ingenious methods were therefore devised to insure the taking of game in large numbers at one time. This was especially the case with the buffalo, which were the food and raiment of the people. One of these contrivances was called pis'kun, deep-kettle; or, since the termination of the word seems to indicate the last syllable of the word ah'-pun, blood, it is more likely deep-blood-kettle. This was a large corral, or enclosure, built out from the foot of a perpendicular cliff or bluff, and formed of natural banks, rocks, and logs or brush,—anything in fact to make a close, high barrier. In some places the enclosure might be only a fence of brush, but even here the buffalo did not break it down, for they did not push against it, but ran round and round within, looking for a clear space through which they might pass. From the top of the bluff, directly over the pis'kun, two long lines of rock piles and brush extended far out on the prairie, ever diverging from each other like the arms of the letter V, the opening over the pis'kun being at the angle.
In the evening of the day preceding a drive of buffalo into the pis'kun a medicine man, usually one who was the possessor of a buffalo rock, In-is'-kim, unrolled his pipe, and prayed to the Sun for success. Next morning the man who was to call the buffalo arose very early, and told his wives that they must not leave the lodge, nor even look out, until he returned; that they should keep burning sweet grass, and should pray to the Sun for his success and safety. Without eating or drinking, he then went up on the prairie, and the people followed him, and concealed themselves behind the rocks and bushes which formed the V, or chute. The medicine man put on a head-dress made of the head of a buffalo, and a robe, and then started out to approach the animals. When he had come near to the herd, he moved about until he had attracted the attention of some of the buffalo, and when they began to look at him, he walked slowly away toward the entrance of the chute. Usually the buffalo followed, and, as they did so, he gradually increased his pace. The buffalo followed more rapidly, and the man continually went a little faster. Finally, when the buffalo were fairly within the chute, the people began to rise up from behind the rock piles which the herd had passed, and to shout and wave their robes. This frightened the hinder-most buffalo, which pushed forward on the others, and before long the whole herd was running at headlong speed toward the precipice, the rock piles directing them to the point over the enclosure. When they reached it, most of the animals were pushed over, and usually even the last of the band plunged blindly down into the pis'kun. Many were killed outright by the fall; others had broken legs or broken backs, while some perhaps were uninjured. The barricade, however, prevented them from escaping, and all were soon killed by the arrows of the Indians.
It is said that there was another way to get the buffalo into this chute. A man who was very skilful in arousing the buffalo's curiosity, might go out without disguise, and by wheeling round and round in front of the herd, appearing and disappearing, would induce them to move toward him, when it was easy to entice them into the chute. Once there, the people began to rise up behind them, shouting and waving their robes, and the now terror-stricken animals rushed ahead, and were driven over the cliff into the pis'kun, where all were quickly killed and divided among the people, the chiefs and the leading warrior getting the best and fattest animals.
The pis'kun was in use up to within thirty-five or forty years, and many men are still living who have seen the buffalo driven over the cliff. Such men even now speak with enthusiasm of the plenty that successful drives brought to the camp.
The pis'kuns of the Sik'-si-kau, or Blackfoot tribe, differed in some particulars from those constructed by the Bloods and the Piegans, who live further to the south, nearer to the mountains, and so in a country which is rougher and more broken. The Sik'-si-kau built their pis'kuns like the Crees, on level ground and usually near timber. A large pen or corral was made of heavy logs about eight feet high. On the side where the wings of the chute come together, a bridge, or causeway, was built, sloping gently up from the prairie to the walls of the corral, which at this point were cut away to the height of the bridge above the ground,—here about four feet,—so that the animals running up the causeway could jump down into the corral. The causeway was fenced in on either side by logs, so that the buffalo could not run off it. After they had been lured within the wings of the chute, they were driven toward the corral as already described. When they reached the end of the >, they ran up the bridge, and jumped down into the pen. When it was full, or all had entered, Indians, who had lain hidden near by, ran upon the bridge, and placed poles, prepared beforehand, across the opening through which the animals had entered, and over these poles hung robes, so as entirely to close the opening. The buffalo will not dash themselves against a barrier which is entirely closed, even though it be very frail; but if they can see through it to the outside, they will rush against it, and their great weight and strength make it easy for them to break down any but a heavy wall. Mr. Hugh Monroe tells me that he has seen a pis'kun built of willow brush; and the Cheyennes have stated to me that their buffalo corrals were often built of brush. Sometimes, if the walls of the pis'kun were not high, the buffalo tried to jump or climb over them, and, in doing this, might break them down, and some or all escape. As soon, however, as the animals were in the corral, the people—women and children included—ran up and showed themselves all about the walls, and by their cries kept the buffalo from pressing against the walls. The animals ran round and round within, and the men standing on the walls shot them down as they passed. The butchering was done in the pis'kun, and after this was over, the place was cleaned out, the heads, feet, and least perishable offal being removed. Wolves, foxes, badgers, and other small carnivorous animals visited the pis'kun, and soon made away with the entrails.
In winter, when the snow was on the ground, and the buffalo were to be led to the pis'kun, the following method was adopted to keep the herd travelling in the desired direction after they had got between the wings of the chute. A line of buffalo chips, each one supported on three small sticks, so that it stood a few inches above the snow, was carried from the mouth of the pis'kun straight out toward the prairie. The chips were about thirty feet apart, and ran midway between the wings of the chute. This line was, of course, conspicuous against the white snow, and when the buffalo were running down the chute, they always followed it, never turning to the right nor to the left. In the latter days of the pis'kun, the man who led the buffalo was often mounted on a white horse.
Often, when they drove the buffalo over a high vertical cliff, no corral was built beneath. Most of those driven over were killed or disabled by the fall, and only a few got away. The pis'kuns, as a rule, were built under low-cut bluffs, and sometimes the buffalo were driven in by moonlight.
In connection with the subject of leading or decoying the buffalo, another matter not generally known may be mentioned. Sometimes, as a matter of convenience, a herd was brought from a long distance close up to the camp. This was usually done in the spring of the year, when the horses were thin in flesh and not in condition to stand a long chase. I myself have never seen this; but my friend, William Jackson, was once present at such a drive by the Red River half-breeds, and has described to me the way in which it was done.
The camp was on Box Elder Creek near the Musselshell River. It was in the spring of 1881, and the horses were all pretty well run down and thin, so that their owners wished to spare them as much as possible. The buffalo were seven or eight miles distant, and two men were sent out to bring them to the camp. Other men, leading fresh horses, went with them, and hid themselves among the hills at different points along the course that the buffalo were expected to take, at intervals of a mile and a half. They watched the herd, and were on hand to supply the fresh horses to the men who were bringing it.
