These flint celts are usually rough, but frequently present a very high polish, indicating a long and continued use. Particularly is this polish noticed on the edges. The form of them does not vary as much as the forms of the celts in granite, limestone, sandstone, porphyry, or other materials. But flint celts may be divided into two classes, the oval form and the form with the sides somewhat square. I think the latter class represents the art of more skillful workmen. The specimens thus made are more nearly like the European type of square flint celts than are our other prehistoric implements. Flint axes form, of course, a separate division or class from the celts.
Fig. 178. (S. 1–2.) Five flint celts from the collection of S. D. Mitchell, Ripon, Wisconsin. Such are found in Wisconsin as well as other parts of the country.

Fig. 180. (S. 1–2.) Ten flint celts of various types, Phillips Academy collection, Andover. These are of chert, jasper, and argillite, and were found in Kentucky, Arkansas, Missouri, and Iowa. They range from square celts to oval, although the cutting edge is usually at one end.
