Sorcery or witchcraft has already been noticed, but we may in addition state that the witchcraft imputed to some of their doctors is their power to do evil at a great distance from the object, to produce death or disease, though they do not believe these persons can transform themselves into other shapes; think they can exercise the same power to do good if they choose, and do exercise it in curing the sick. It is in consequence of this belief that the doctor or divining man is punished in case of failure and death, as they think it is his unwillingness, not his inability, to cure which produces the result. They do not burn them, but the writer has seen several shot at different times by the relatives of the deceased, on the supposition they caused their death. This custom is in as great force now as it ever was.

The divining man has a chance to become rich in horses and other property in a short time, as his fees depend on himself; but these advantages are more than counterbalanced by the risk attending the profession. The doctor, priest, conjuror, wizard, prophet, and divining man are all united in the same person; that is, to a divining man (Wa-con), or divining woman (Wa-can), these powers, or some of them, are ascribed, and they are believed to possess them in proportion as their success has been developed. Some are simply doctors of medicine, others in addition are conjurors and do tricks. Some go further, interpret dreams, reveal the future, find lost articles, etc. The whole united forms the entire divining man. The persons who profess and perform some of these things are tolerably numerous; but the effective diviner of established reputation, large practice, and possessing the whole of the foregoing powers are very few, perhaps not more than six or eight in the whole Assiniboin Nation. As has been observed, they form no distinct body and have but little influence in council unless they can add that of warrior to their many distinguished titles and degrees.

Indian Tribes of the Upper Missouri — Part 108

The whole of these Indians most sincerely believe in the theory of ghosts, that departed spirits have the power to make themselves visible and heard, that they can assume any shape they wish, of animals or men, and many will affirm that they have actually seen these apparitions and heard their whistlings and moanings. They are much afraid of these appearances, and under no consideration will go alone near a burial place after dark. They believe these apparitions have the power of striking the beholder with some disease, and many complaints are attributed to this cause. They therefore make feasts and prayers to them to remain quiet. Smaller evils and misfortunes are caused by their power, and a great many stories are nightly recounted in their lodges of the different shapes in which they appear.
