The position and ease attendant upon a reputation for medicine power cause many unsuccessful pretenders to embrace the profession; and it would seem strange that their failures should not have brought medicine into disrepute. In looking closely into this, a well-marked distinction will always be found between _medicine_ and the _medicine-man_,--quite as broad as is made with us between religion and the preacher. I have seen would-be medicine-men laughed at through the camp,--men of reputation as warriors, and respected in council, but whose _forte_ was not the reading of dreams or the prediction of events. On the other hand, I have seen persons of inferior intellect, without courage on the war-path or wisdom in the council, revered as the channels through which, in some unexplained manner, the Great Spirit warned or advised his creatures. Of course it is no purpose of this paper to uphold or attack these peculiar ideas. A meagre presentation of a few facts not generally known is all that is aimed at. Whether the system of Indian medicine be a variety of Mesmerism, Magnetism, Spiritualism, or what not, others may inquire and determine. One bred a Calvinist, as was the writer, may be supposed to have viewed with suspicion the exhibitions of medicine power that almost daily presented themselves. And while, in very numerous instances, they proved to be but the impudent pretensions of charlatans, it must be conceded, if credible witnesses are to be believed, that sometimes there is a power of second-sight, or something of a kindred nature, which defies investigation. Instances of this kind are of frequent occurrence, and easily recalled, I venture to say, by every one familiar with the Indian in his native state. The higher powers claimed for medicine are, in general, doubtfully spoken of by the Indians. Not that they deny the possibility of the power, but they question the probability of so signal a mark of favor being bestowed on a mere mortal. Powers and medicine privileges of a lower degree are more readily acknowledged. An aged Indian of the Assinaboin tribe is very generally admitted, by his own and neighboring tribes, to have been shown the happy hunting-grounds, and conducted through them and returned safely to the camp of his tribe, by special favor of the Great Spirit. He once drew a map of the Indian paradise for me, and described its pleasant prairies and crystal rivers, its countless herds of fat buffalo and horses, its perennial and luxuriant grass, and other charms dear to an Indian's heart, in a rhapsody that was almost poetry. Another, an obscure man of the Cathead Sioux, is believed to have seen the hole through which issue the herds of buffalo which the Great Spirit calls forth from the centre of the earth to feed his children.
