Fig. 101.—Discoidal stone.

C. Sides flat; edges straight, sometimes rounding off into the sides; diameter, 2¼ to 6 inches; thickness, three-quarters to 2¼ inches. A number from southeastern Tennessee, especially the smaller ones, are quite rough, being merely pecked or chipped into shape with no subsequent rubbing. [Figure 101] (chalcedony, from a mound in Monroe county, Tennessee) represents the type. The material is variable.

I = Quartzite.

D. Like the last, except much smaller. Very few are polished over the entire surface; some are rubbed more or less on the edges or sides, but a majority have the edge rough as it was chipped or pecked out; many have either the edge or sides in the natural state. From those smoothly polished to those very rudely worked the gradation is such that no dividing line can be drawn. This is true, also, of the smaller specimens of other types. Some of the quartzite specimens are very loose in texture. From seven-eighths to 2 inches in diameter and one-fourth to three-fourths of an inch thick.

Fig. 102.—Discoidal stone, convex.

E. Convex on both sides, edges straight. One of white quartz from Caldwell county, North Carolina, has the sides much curved, making the stone very thick in proportion to its width; there is a deep pit on each side, the entire surface being highly polished. Diameter, 2 to 3½ inches; thickness, three-fourths to an inch and a half. Illustrated by [figure 102] (of porphyry, from a grave in Caldwell county, North Carolina).
