ERA OF THE IMPORTATION OF THE HORSE.—When the horse was first introduced among them does not appear by any of the traditions of these ignorant people. The name of the horse in Assiniboin is shunga (dog) tunga (large), i. e., large dog. Among the Sioux it is named shunka (dog) wakan (divining), i. e., divining dog, which would only prove that the dog was anterior to the horse, inasmuch as they were obliged to make a name for the strange animal resembling some known object with which it could be afterwards compared. PICTOGRAPHS CHARTS ON BARK.—Their drawings of maps and sections of country are in execution miserable to us but explanatory among themselves. Most Indians can carve on a tree, or paint, who they are, where going, whence come, how many men, horses, and guns the party is composed of, whether they have killed enemies, or lost friends, and, if so, how many, etc., and all Indians passing by, either friends or foes, will have no difficulty in reading the same, though such representations would be quite unintelligible to whites unless instructed. (Pl. 64.) Some Indians have good ideas of proportion and can immediately arrive at the meaning of a picture, pointing out the objects in the background, though others can not distinguish the figure of a man from that of a horse, and as to their executions of any drawing they are rude in the extreme. Where the natural talent exists, however, there is no doubt they could be instructed. ANTIQUITIES From the Sioux to the Blackfeet, inclusive, there is not in all that country any mounds, teocalli, or appearances of former works of defense bearing the character of forts or any other antique structure. Not a vestige or relic of anything that would form data, or be an inducement to believe their grounds have ever been occupied by any other than roving tribes of wild Indians; nor in the shape of tools, ornaments, or missiles that would lead to any such inference. We have not been more fortunate in searching their traditions in the hope of finding some clue relative to these things. They do not believe that any persons ever occupied their country except their own people (Indians), and we can not say we have ever seen or heard anything to justify any other conclusion regarding the extent of territory mentioned.
