To propitiate his favor they offer to him annual sacrifices of salmon and venison, the first fruits of their fishing and hunting.
Besides this aerial spirit they believe in an inferior one, who inhabits the fire, and of whom they are in perpetual dread, as, though he possesses equally the power of good and evil, the evil is apt to predominate.

They endeavor, therefore, to keep him in good humor by frequent offerings.

He is supposed also to have great influence with the winged spirit, their sovereign protector and benefactor.

They implore him, therefore, to act as their interpreter, and procure them all desirable things, such as success in fishing and hunting, abundance of game, fleet horses, obedient wives, and male children.
These Indians have likewise their priests, or conjurers, or medicine men, who pretend to be in the confidence of the deities, and the expounders and enforcers of their will.

Each of these medicine men has his idols carved in wood, representing the spirits of the air and of the fire, under some rude and grotesque form of a horse, a bear, a beaver, or other quadruped, or that of bird or fish.
