FIG. 387. (S. 1–4.) This series of fourteen circular stones, with depressed centres, and most of them perforated, is from the Andover collection. They represent the smaller bicave or discoidal stones. All of them are fine and interesting specimens. Materials: sandstone, clay, and granite. Localities: Kentucky, Tennessee, Indiana, and Ohio. ] [Illustration: FIG. 388. (S. 1–4.) Discoidal stones from Kentucky; valley of the Cumberland River. The central one is of slate. B. H. Young’s collection, Louisville, Kentucky. ] Discoidals may be common, circular discs with flat polished sides, or circular with concave sides and perforated through the centre, or with the centre rimmed out, as certain specimens in Fig. 387. In this figure all are bicaves save three. That all of these small ones were used in playing chunky games I do not believe. They may have served as gaming-stones in other events. Some of the ruder ones, of the small stones I mean, may have been spindle-whorls. [Illustration: FIG. 389. (S. 1–3.) Phillips Academy collection. Locality: Tennessee. Material: quartz and quartzite. ] Fig. 389 shows four beautiful specimens from Tennessee, Andover collection. These are not merely depressed in the centre, but have a high, fluted rim, the centre being cut out, and the surfaces on the inside of the rim either sloping toward a second depression in the centre, or made flat. All are highly polished, and of Tennessee marble or quartz. The colors vary from rich brown to spotted, with yellow predominating. Fig. 388, from Colonel Young’s magnificent collection, illustrates nine bicaves of various sizes and materials—the black slate one in the centre, flanked by those of beautifully mottled quartz on either side, and one of pure white quartz to the right of the centre. Fig. 391 is a remarkable object with a slightly depressed top, and with the central depression plainly marked. Around this central depression is a rim. In the “Handbook of American Indians,” page 391, Mr. Fowke has described the bicaves, and his description I here quote, as it is the best published up to this time:— [Illustration: FIG. 390. (S. 1–2.) Barrel-shaped bicave. Hard, light-colored material. B. H. Young’s collection, Louisville, Kentucky. ] [Illustration: FIG. 391. (S. 1–2.) Quartzite bicave found on sandy bank of Hightower River, Cherokee County, Georgia. Weight, 37 ounces. Translucent between the depressions. Pink by reflected light and pink by transmitted light. It has a perfect secondary depression, and is highly polished and perfect. H. M. Whelpley’s collection, St. Louis, Missouri. ] [Illustration: FIG. 392.
