In the tribe of Moquis there are two fraternities known as the Antelopes and the Snakes, Each has from twenty to thirty members, some of whom are boys who serve as acolytes. When the open air ceremony of the Snake Dance begins, the members of these brotherhoods appear scantily clothed, with their faces painted red and white, and with tortoise-shell rattles tied to their legs. The Antelope fraternity first enters the square, preceded by a venerable priest carrying two bags filled with snakes. These serpents, which have been previously washed and covered with sacred meal, are deposited by the priest in a small leaf-embowered enclosure called the _kisi_. Around this the Antelopes now march, stamping with the right foot violently, to notify the spirits of their ancestors (presumably in the lower world) that the ceremony has begun. After making the circuit of the enclosure four times, they halt, and stand in line with their backs turned toward it. Then the Snake fraternity appears, headed by its priest, and performs the same ceremony. Then they too form a line, facing the Antelopes, and all of them, for about five minutes, wave their wands and chant some unintelligible words. Suddenly one Antelope and one Snake man rush to the _kisi_, and the priest who is presiding over the serpents presents them with a snake. The Snake man immediately places the wriggling reptile in his mouth, and holds it by the centre of its body between his teeth, as he marches around the little plaza, taking high steps. Meantime the, Antelope man accompanies him, stroking the snake continually with a wand tipped with feathers. Then all the members of the two fraternities follow in couples and do the same thing. Finally, each Snake man carries at least two snakes in his mouth and several in his hands; and even little boys, five years old, dressed like the adults, also hold snakes in their hands, fearlessly. Once in a while a snake is purposely dropped, and a man whose special duty it is to prevent its escape rushes after it and catches it up.
All the time that this hideous ceremony is going on, a weird chant is sung by the men and women of the tribe; and, at last, the chief priest draws on the ground a mystic circle with a line of sacred meal, and into this the men unload their snakes until the whole space becomes a writhing mass of serpents. Suddenly the members rush into this throng of squirming reptiles, most of which are rattlesnakes, and each, grabbing up a handful of them, runs at full speed down the _mesa_ and sets them at liberty, to act as messengers to carry to the gods their prayers for rain. This ends the ceremony for the snakes, but not for the men; for after they have liberated the reptiles, the members of the brotherhoods return and bathe themselves in a kind of green decoction, called Frog-water. Then they drink a powerful emetic, and having lined up on the edge of the _mesa_, vomit in unison! This is to purge them from the evil effects of snake-handling; and lest it should not be sufficiently effectual, the dose is repeated. Then they sit down, and eat bread, given them by the women as a kind of communion or religious rite.
