We seldom find axes, pestles, spades, and grooved stone hammers in mounds or graves. I never knew of more than two instances in the whole United States where pestles were buried in ancient graves, and I never knew of a single find of pitted hammer-stones in a prehistoric mound or grave. This does not mean that the Indian regarded labor as beneath him. It means that he drew a special line of demarcation between those ideals which concerned his “mystery,” and the affairs of everyday life. His religion, or as unthinking people have called it, his superstition, he placed first. He worshiped the Unknown in the air and sky above. Naturally, he showed respect to the dead, and perhaps not so much to the person of the dead as to that estate into which the deceased entered. Truly, one might say that “nothing unclean or common” was placed by him with the dead, or offered as a sacrifice to the spirits. For this very reason I maintain that while the Indian would spend hours of rigorous laborious work upon bringing to perfection certain art forms or weapons, he would not employ these in the manufacture of commoner implements, ornaments, or other forms. But on the contrary, prompted by his high regard for stone objects of the character of these long and slender flint ornaments, he made use of more serviceable and common things as tools. Therefore, it was natural for him to select a reed, or a stout hickory stick, or a heavy flint drill instead of an object that will chip or break in the course of five or ten minutes drilling. There is yet another use to which I believe some of the finest perforators was put, which I state as my opinion merely. Among the Crows, Mandans, Sioux, and other Indians were common, in the days of Lewis and Clark, necklaces of long bones of three to four and sometimes five inches in length arranged in parallel rows. These were highly prized. One of these breast ornaments was presented to me by Mah-een-gonce, a chief of the Ojibway, at a squaw dance in August, 1909, at White Earth Reservation. While it is my opinion that such objects as are shown in Figs. 199 and 202 were not used as drills, I should like to offer the suggestion that they served other purposes. Perhaps they were made use of as hairpins, possibly they were fastened to strips of buckskin, several of them being worn in parallel rows. Mounted in that manner they would form unique ornaments and appeal to aboriginal fancy. CACHED FLINT OBJECTS These would follow, according to classification, under knives and projectile points without stem—“C,” more or less circular. [Illustration:
