There was no evidence that the former inhabitants of these buildings were acquainted with metals. The ends of the beams had been hacked off evidently with blunt stone axes, aided by fire, and the lintels of the houses were of split logs which showed no evidence that any metal implement was used in fashioning them. We found, however, several stone tools, which exhibit considerable skill in the art of stone working. These include a single ax, blunt at one end, sharpened at the other, and girt by a single groove. The variety of stone from which the ax was made does not occur in the immediate vicinity of the ruin. There were one or two stone hammers, grooved for hafting, like the ax. A third stone maul, being grooveless, was evidently a hand tool for breaking other stones or for grinding pigments. [Illustration: FIG. 251--Stone implement from Honanki] Perhaps the most interesting stone implement which was found was uncovered in the excavation of one of the middle rooms of the western part of the ruin, about three feet below the surface. It consists of a wooden handle rounded at each end and slightly curved, with a sharpened stone inserted midway of its length and cemented to the wood with pitch or asphaltum. The stone of this implement would hardly bear rough usage, or sustain, without fracture, a heavy blow. The edge is tolerably sharp, and it therefore may have been used in skinning animals. Judging from the form of the handle, the implement is better suited for use as a scraper than for any other purpose which has occurred to me (figure 251). The inhabitants of the two ruins of the Red-rocks used obsidian arrowpoints with shafts of reeds, and evidently highly regarded fragments of the former material for knives, spearheads, and one or two other purposes. The stone metates from these ruins are in no respect characteristic, and several fine specimens were found in place on the floors of the rooms. One of these was a well-worn specimen of lava, which must have been brought from a considerable distance, since none of that material occurs in the neighborhood. The existence of these grinding stones implies the use of maize as food, and this evidence was much strengthened by the finding of corncobs, kernels of corn, and charred fragments at several points below the surface of the débris in the chambers of Honanki. One of these grinding stones was found set in the floor of one of the rooms in the same way that similar metates may be seen in Walpi today.
