Another sacred object is the medicine rock of the Marias. It is a huge boulder of reddish sandstone, two-thirds the way up a steep hill on the north bank of the Marias River, about five miles from Fort Conrad. Formerly, this rock rested on the top of the bluff, but, as the soil about it is worn away by the wind and the rain, it is slowly moving down the hill. The Indians believe it to be alive, and make presents to it. When I first visited it, the ground about it was strewn with decaying remnants of offerings that had been made to it in the past. Among these I noticed, besides fragments of clothing, eagle feathers, a steel finger ring, brass ear-rings, and a little bottle made of two copper cartridge cases.
Down on Milk River, east of the Sweet Grass Hills, is another medicine rock. It is shaped something like a man's body, and looks like a person sitting on top of the bluff. Whenever the Blackfeet pass this rock, they make presents to it. Sometimes, when they give it an article of clothing, they put it on the rock, "and then," as one of them once said to me, "when you look at it, it seems more than ever like a person." Down in the big bend of the Milk River, opposite the eastern end of the Little Rocky Mountains, lying on the prairie, is a great gray boulder, which is shaped like a buffalo bull lying down. This is greatly reverenced by all Plains Indians, Blackfeet included, and they make presents to it. Many other examples of similar character might be given.
The Blackfeet make daily prayers to the Sun and to Old Man, and nothing of importance is undertaken without asking for divine assistance. They are firm believers in dreams. These, they say, are sent by the Sun to enable us to look ahead, to tell what is going to happen. A dream, especially if it is a strong one,—that is, if the dream is very clear and vivid,—is almost always obeyed. As dreams start them on the war path, so, if a dream threatening bad luck comes to a member of a war party, even if in the enemy's country and just about to make an attack on a camp, the party is likely to turn about and go home without making any hostile demonstrations. The animal or object which appears to the boy, or man, who is trying to dream for power, is, as has been said, regarded thereafter as his secret helper, his medicine, and is usually called his dream (Nits-o'-kan).
The most important religious occasion of the year is the ceremony of the Medicine Lodge. This is a sacrifice, which, among the Blackfeet, is offered invariably by women. If a woman has a son or husband away at war, and is anxious about him, or if she has a dangerously sick child, she may make to the Sun a vow in the following words:—
"Listen, Sun. Pity me. You have seen my life. You know that I am pure. I have never committed adultery with any man. Now, therefore, I ask you to pity me. I will build you a lodge. Let my son survive. Bring him back to health, so that I may build this lodge for you."
The vow to build the Medicine Lodge is repeated in a loud voice, outside her lodge, so that all the people may hear it, and if any man can impeach the woman, he is obliged to speak out, in which case she could be punished according to the law. The Medicine Lodge is always built in summer, at the season of the ripening of the sarvis berries, and if, before this time, the person for whom the vow is made dies, the woman is not obliged to fulfil her vow. She is regarded with suspicion, and it is generally believed that she has been guilty of the crime she disavowed. As this cannot be proved, however, she is not punished.
When the time approaches for the building of the lodge, a suitable locality is selected, and all the people move to it, putting up their lodges in a circle about it. In the meantime, at least a hundred buffalo tongues have been collected, cut, and dried by the woman who may be called the Medicine Lodge woman. No one but she is allowed to take part in this work.
Before the tongues are cut and dried, they are laid in a pile in the medicine woman's lodge. She then gives a feast to the old men, and one of them, noted for his honesty, and well liked by all, repeats a very long prayer, asking in substance that the coming Medicine Lodge may be acceptable to the Sun, and that he will look with favor on the people, and will give them good health, plenty of food, and success in war. A hundred songs are then sung, each one different from the others. The feast and singing of these songs lasts a day and a half.[Illustration: MEDICINE LODGE]
Before the Medicine Lodge is erected, four large sweat lodges are built, all in a line, fronting to the east or toward the rising sun. Two stand in front of the Medicine Lodge, and two behind it. The two nearest the Medicine Lodge are built one day, and the others on the day following. The sticks for the framework of these lodges are cut only by renowned warriors, each warrior cutting one, and, as he brings it in and lays it down, he counts a coup, which must be of some especially brave deed. The old men then take the sticks and erect the lodges, placing on top of each a buffalo skull, one half of which is painted red, the other black, to represent day and night, or rather the sun and the moon. When the lodges are finished and the stones heated, the warriors go in to sweat, and with them the medicine pipe men, who offer up prayers.
While this is going on, the young men cut the centre post for the Medicine Lodge, and all the other material for its construction. The women then pack out the post and the poles on horses, followed by the men shouting, singing, and shooting.
