In Fig. 224 there are shown eight celts from the collection of Phillips Academy, Andover. They come from various portions of the United States. In the upper row at either side are typical oval celts, with this difference, that the one to the right has a broad cutting edge, and the one to the left is quite convex, with poll and edge of equal width. This approaches the chisel type. In the centre of the top row is a roughly pecked, unpolished celt, the poll of which is narrowed for the purpose of fitting it into a handle. [Illustration: FIG. 231. (S. about 1–3.) Reproduced from Baron G. Nordenskiöld’s “Cliff-Dwellers of the Mesa Verde,” pl. 36. ] In the central row are three celts. (Class D.) The surfaces presented in the figure are flat, and beveled off toward the edge; the other surface being convex. In the lower row is a small chisel-like celt with wide poll or top, and narrow cutting edge. Such specimens as are shown in Fig. 225 are not only celts, but stone tools which are pointed at either end. If space permitted, I should be glad to present more of these implements, for they range from long, slender, pointed tools to celts, and include many objects which other observers might place in the problematical class. Aside from three of them shown in Fig. 225, there are illustrated two in Figs. 237, 238. There is also a large specimen about a foot in length in the Andover collection. Dr. Beauchamp says of Fig. 225:— “The figure to the left is reduced in size to about one half, as are also the nine other specimens in the illustration. This left-hand figure is of a rare and peculiar celt, several of which have been found. They are very slender, usually nearly cylindric, and more or less pointed at each end. Sometimes the material seems too frail for use. It is angular and four-sided, but the angles are rounded, and the points likewise. It tapers to each end, and shows no signs of use. The material is a polished dark gritty slate, from Seneca River. [Illustration: FIG. 232. (S. 1–3.) A stone celt mounted in a wooden handle. From the collection of the Peabody Museum, Salem, Massachusetts. This was found on the Northwest Coast, and was in use among natives many years ago, and was brought to the Salem institution by a “whaler,” as were many other specimens in the Salem collections. ] “The figure to the right might be classed as an adze. One surface is nearly a plane, and the other curves to each sharp end. It is of sandstone, from Brewerton, N. Y., and a rare form for the size.” All through the Cliff-Dweller country the celts almost approach knives in character. In Fig. 231 we observe three fine stone celt-like knives from ruins in southwestern Colorado. They all have broad cutting-blades and narrow polls.
