§ 292. Bushotter names two kinds of Dakota doctors--the Mato wapiya, or Grizzly Bear doctor, who is very wakan, and the Peźuta wapiya, or Peźuta wićaśa, the doctor who prescribes roots. The person who practices medicine claims to have had interviews with the spirits, but he never reveals what the spirits have told him, though he says that immediately after the revelation made him by the spirit he begins to act according to its directions. And in some cases of sickness this doctor takes the flesh of the patient into his mouth and makes a sucking sound while inhaling, and from the patient’s side he pretends to remove something. When he has made the sucking sound after taking the flesh into his mouth, or when he has taken blood or something else from the side of the patient, he spits it from his mouth. Then he sees the patient’s mother, whom he tells what is the cause of the disease, and whether the patient will recover or die. Such doctors pretend to have within themselves one of the following: A small red hawk, a common woodpecker, a real buffalo, a rattlesnake, or a grizzly bear. And when one of these doctors kicks on the ground there is heard something within him, singing in a beautiful voice; and so the people believe what the doctors say about diseases. § 293. When the doctor has sucked the patient’s flesh a long time without removing anything, he asks a favor of the mysterious being dwelling within himself, and then that being cries out often, and the doctor succeeds in his efforts. It is by the aid of these mysterious beings that the doctors are enabled to practice medicine. In the olden time one of the doctors was very mysterious. Once, when he was practicing, a bowl of water was set down before him. He vomited into the bowl and a water-snake appeared in it. But when the doctor opened his mouth again the snake glided gently into it and disappeared down his throat. Such exhibitions by the doctors have been observed by the Indians, who are constrained to believe what the doctors claim for themselves. And because they believe that the doctors are very mysterious, the latter are able to gather together many possessions as pay for their services. Therefore the men and women doctors try to excel one another in their skill, as it pays them so well.
