fears, he will continue to say his medicine is good, but should he be disappointed and the case reversed, he will throw the charm away and substitute some other. Thus the writing, paintings, and pictures done by whites are considered great charms by some Indians, particularly the Crows, and are eagerly sought after as such. In the same light is regarded the medal of the crucifixion given them, by Catholic priests. What is the actual character of their worship when closely analyzed? It is hoped that the preceding remarks have rendered this character plain. All their prayers, sacrifices, feasts and personal inflictions tend only to advance their temporal welfare and interest. Several tunes are sung on some of these occasions when presenting the pipe to the Sun, etc., that are of a sacred character, partaking of the nature of thanksgiving for any signal success in war or otherwise. A few words are used, but the chant is solemnly performed without their usual gesticulations or levity. The custom of holding as sacred the cult of the tobacco plant is general. No ceremony of importance takes place among them in which the pipe is not used. There are, however, several solemn occasions in which the manufactured tobacco will not answer, when they use that grown by themselves. These customs occur among the Mandan, Gros Ventres, Arikara, and Crows, the only nations who cultivate the tobacco plant. Sacrifices of small quantities of tobacco are also made on many occasions, and always a small piece is found wrapped with the medicine pipe or inclosed in the medicine sack. Why it is considered sacred they can not explain, and the idea appears one of the most ancient and original among them.
