Dreams are revelations of Great Mystery and have considerable influence over them, either in war expeditions or the chase. A bad dream on the part of the leader of a war party would be sufficient cause for their return, even if they were within a short distance of their enemies. It would also prevent an Indian from his customary hunting and have other effects of the like nature for a short time. Good dreams are therefore always desired and courted, particularly on the eve of war excursions. Faith in amulets and charms is general among the whole of these tribes. The material of these charms is of every possible variety, as also the different degrees of influence they exercise over different minds. The idea though thoroughly realized by ourselves is difficult to explain, but may be thus stated: Although the Great Spirit is all powerful, yet His will is uncertain; He is invisible and only manifests His power in extraordinary circumstances. The want of a tangible medium is felt, therefore, through which they can offer their prayers to all ghosts, lesser influences of evil, which overrule their ordinary occupations. Each Indian selects some object for this purpose and calls it his medicine, which is invested with a sacred character by the care with which it is guarded and the prayers, invocations, etc., made through it as a medium. This charm or fetish is chosen in consequence of some dream or incident or idea presented on some important occasion, and consists of the skin of a weasel, otter, or beaver; heads and bodies of different kinds of birds, stuffed; images of wood, stone, and beads wrought upon skin; drawings of bulls, bears, wolves, owls, serpents, monsters, who have never existed; even a bullet worn round the neck; in fact anything resembling animate, inanimate, or imaginative creation, is selected according to the superstitious fancy of the individual. This charm, whatever it is, is inclosed in several envelopes of skin, and placed in a rawhide sack which is painted and fringed in various ways. This sack is never opened in the presence of anyone unless the Indian falls sick, when he has it taken out and placed at his head. Ordinarily this object is taken out in secret, and prayers and invocations made through it as a medium to the spirits he wishes to propitiate. They are aware that the object has no intrinsic power, but its virtue lies in their faith of their ceremonies, as exhibited through this charm as a visible medium to the supernatural. It is in fact the same operation of mind (though differently exhibited) as is displayed in the charms believed in by most of the lower order of whites. Although many ignorant white persons have faith in the charms, spells, etc., of quack doctors and old women, yet this does not destroy their belief in the Supreme Being, neither does it that of the Indian. As long as he has success in his different ordinary undertakings and is not troubled with the evils he
