The dancing part is performed by the old and young squaws.

The medicine men sing, beat the drum, rattle the gourd, and use such other instruments as they contrive.

Anything is considered a musical instrument that will assist in creating discordant sound.

One of these is a bone with notches on it, one end of which rests on a tin pan, the other being held in the left hand, while, with a piece of bone in the right, which a medicine man draws over the notches, sounds as discordant and grating as possible are created.
The squaws dance around the scalps in concentric circles, in groups of from four to twelve together, pressing their shoulders against each other, and at every stroke of the drum raising themselves to their utmost height, hopping and sliding a short distance to the left, singing all the time with the medicine men.

They keep time perfectly.
