"Wait and we'll see," replied Dick, who guessed too well their purpose, although he could not help but look.

The neophytes advanced, and every one tied one of the long rawhide thongs depending from the top of the pole to the loop of cord that hung from his breast. When all were ready they formed a great circle, somewhat after the fashion of the dancers around a Maypole, and outside of those formed another and greater circle of those already initiated.

A medicine man began to blow a small whistle made from the wing bone of an eagle, the sacred bird of the Sioux, and he never stopped blowing it for an instant. It gave forth a shrill, penetrating sound, that began after a while to work upon the nerves in a way that was almost unendurable to Dick and Albert.

At the first sound of the whistle the warriors began to dance around the pole, keeping time to the weird music. It was a hideous and frightful dance, like some cruel rite of a far-off time. The object was to tear the peg from the body, breaking by violence through the skin and flesh that held it, and this proved that the neophyte by his endurance of excessive pain was fit to become a great warrior.

But the pegs held fast for a long time, while the terrible, wailing cry of the whistle went on and on. Dick and Albert wanted to turn away—in fact, they had a violent impulse more than once to run from it—but the eyes of the Sioux were upon them, and they knew that they would consider them cowards if they could not bear to look upon that which others no older than themselves endured. There was also the incessant, terrible wailing of the whistle, which seemed to charm them and hold them.

The youths by and by began to pull loose from the thongs, and in some cases where it was evident that they would not be able to do so a medicine man would seize them by the shoulders and help pull. In no case did a dancer give up, although they often fell in a faint when loosed. Then they were carried away to be revived, but for three days and three nights not a single neophyte could touch food, water, or any other kind of drink. They were also compelled, as soon as they recovered a measurable degree of strength, to join the larger group and dance three days and nights around the neophytes, who successively took their places.

The whole sight, with the wailing of the whistle, the shouts of the dancers, the beat of their feet, and the hard, excited breathing of the thousands about them, became weird and uncanny. Dick felt as if some strange, deadly odor had mounted to his brain, and while he struggled between going and staying a new shout arose.

A fresh group of neophytes sprang into the inclosed place. Every one of these had the little sticks thrust through the upper point of the shoulder blade instead of the breast, while from the loop dangled a buffalo head. They danced violently until the weight of the head pulled the sticks loose, and then, like their brethren of the pole, joined the great ring of outside dancers when they were able.

The crowd of neophytes increased, as they gave way in turn to one another, and the thong about them thickened. Hundreds and hundreds of dancers whirled and jumped to the shrill, incessant blowing of the eagle-bone whistle. It seemed at times to the excited imaginations of Dick and Albert that the earth rocked to the mighty tread of the greatest of all sun dances. Indian stoicism was gone, perspiration streamed from dark faces, eyes became bloodshot as their owners danced with feverish vigor, savage shouts burst forth, and the demon dance grew wilder and wilder.

The tread of thousands of feet caused a fine, impalpable dust to rise from the earth beneath the grass and to permeate all the air, filling the eyes and nostrils of the dancers, heating their brains and causing them to see through a red mist. Some fell exhausted. If they were in the way, they were dragged to one side; if not, they lay where they fell, but in either case others took their places and the whirling multitude always increased in numbers.
