This figure is often seen worked with porcupine quills on their ornaments. U-mi-ne wah-chippe is a dance given by some one who fears thunder and thus endeavors to propitiate the god and save his own life.

A ring is made of about 60 feet in circumference by sticking saplings in the ground and bending their tops down, fastening them together. In the center of this ring a pole is placed, about 15 feet in height and painted red. From this swings a piece of birch bark cut so as to represent thunder. At the foot of the pole stand two boys and two girls. The boys represent war; they are painted red and hold war clubs in their hands. The girls have their faces painted with blue clay; they represent peace.

On one side of the circle a kind of booth is erected, and about 20 feet from it a wigwam. There are four entrances. When all arrangements for the dance are concluded the man who gives it emerges from his wigwam, dressed up hideously, crawling on all fours toward the booth. He must sing four tunes before reaching it.

In the meantime the medicine men, who are seated in the wigwam, beat time on the drum, and the young men and squaws keep time to the music by hopping on one foot and then on the other, moving around inside the ring as fast as they can. This is continued for about five minutes, until the music stops. After resting a few moments the second tune commences and lasts the same length of time, then the third and the fourth; the Indian meanwhile making his way toward the booth. At the end of each tune a whoop is raised by the men dancers.

After the Indian has reached his booth inside the ring he must sing four more tunes. At the end of the fourth tune the squaws all run out of the ring as fast as possible, and must leave by the same way that they entered, the other three entrances being reserved for the men, who, carrying their war implements, might be accidentally touched by one of the squaws, and the war implements of the Sioux warrior have from time immemorial been held sacred from the touch of woman. For the same reason the men form the inner ring in dancing round the pole, their war implements being placed at the foot of the pole.

When the last tune is ended the young men shoot at the image of thunder, which is hanging to the pole, and when it falls a general rush is made by the warriors to get hold of it. There is placed at the foot of the pole a bowl of water colored with blue clay. While the men are trying to seize the parts of the bark representation of their god they at the same time are eagerly endeavoring to drink the water in the bowl, every drop of which must be drank.

The warriors then seize on the two boys and girls (the representations of war and peace) and use them as roughly as possible, taking their pipes and war-clubs from them and rolling them in the dirt until the paint is entirely rubbed off from their faces. Much as they dislike this part of the dance, they submit to it through fear, believing that after this performance the power of thunder is destroyed.

James’s Long (f) says:

When a Kansas Indian is killed in battle the thunder is supposed to take him up they do not know where. In going to battle each man traces an imaginary figure of the thunder on the soil, and he who represents it incorrectly is killed by the thunder.
