Among the stone implements used as mortuary offerings which were found in the cemeteries, was one made of the same fine lithographic limestone as the so-called _tcamahia_ (plate CLXXI, _g_) which occur on the Antelope altar in the Snake ceremonies. The exceptional character of this fragment is instructive, and its resemblance to the finely polished stone hoes found in other ruins is very suggestive. [Illustration: BUREAU OF AMERICAN ETHNOLOGY SEVENTEENTH ANNUAL REPORT PL. CLXX CORN GRINDER FROM SIKYATKI] There were found many disk-shape stones, pecked on the periphery as if used in grinding pigment or in bruising seeds, and spheroidal stones with a facet worn at one pole as if used for the same or a similar purpose (plate CLXXI, _b_, _c_). A few stone axes and hatchets were also taken from the graves; most of these are rude specimens of stone working, although one of them can hardly be excelled in any other collection. Many arrowpoints were found, but these are in no respect peculiar. They are made of many different kinds of stone, but those of obsidian are the most numerous. They were generally found in numbers, sometimes in bowls. Evidently they had not been attached to shafts when buried, for no sign of the reeds remained. Arrowheads sewed into a bandoleer are still worn as insignia of rank by warriors, and it is probable that such was also true in the past, so that on interment these arrowpoints might have been placed in the mortuary basin deposited by the side of the warrior, as indicative of his standing or rank, and the bandoleer or leather strap to which they were attached decayed during its long burial in the earth. Spearpoints of much coarser make and larger in size than the arrowheads were also found in the graves, and a rare knife, made of chalcedony, showed that the ancient, like the modern Hopi, prized a sharp cutting instrument.
