_Sacrificing_ is also a religious custom with these people, and is performed in many different modes, and on numerous occasions. Of this custom I shall also speak more fully hereafter, merely noticing at present, some few of the hundred modes in which these offerings are made to the Good and Evil Spirits. Human sacrifices have never been made by the Mandans, nor by any of the north western tribes (so far as I can learn), excepting the Pawnees of the Platte; who have, undoubtedly, observed such an inhuman practice in former times, though they have relinquished it of late. The Mandans sacrifice their fingers to the Great Spirit, and of their worldly goods, the best and the most costly; if a horse or a dog, it must be the favourite one; if it is an arrow from their quiver, they will select the most perfect one as the most effective gift; if it is meat, it is the choicest piece cut from the buffalo or other animal; if it is anything from the stores of the Traders, it is the most costly—it is blue or scarlet cloth, which costs them in this country an enormous price, and is chiefly used for the purpose of hanging over their wigwams to decay, or to cover the scaffolds where rest the bones of their departed relations. Of these kinds of sacrifices there are three of an interesting nature, erected over the great medicine-lodge in the centre of the village—they consist of ten or fifteen yards of blue and black cloth each, purchased from the Fur Company at fifteen or twenty dollars per yard, which are folded up so as to resemble human figures, with quills in their heads and masks on their faces. These singular-looking figures, like “_scare crows_” (+plate+ 47), are erected on poles about thirty feet high, over the door of the mystery-lodge, and there are left to decay. There hangs now by the side of them another, which was added to the number a few days since, of the skin of a white buffalo, which will remain there until it decays and falls to pieces.
