Fig. 167.—Portion of Polished Disc (1⁄2).
The other, which appears to have been a complete circle, was broken into several portions, two of which have been recovered. These do not fit into each other, but they are so similar in composition, thickness, polish, and size of curvature, that there can be no doubt they belonged to the same disc. The arc of the larger fragment, which is very nearly a semicircle, indicates that the diameter of the completed circle would be 43⁄4 inches. It is made of a hard, dark, compact stone, highly polished on both sides, and neatly cut at the circumference. It is a quarter of an inch thick at the edge, but becomes gradually a shade thicker towards the centre (Fig. [167]).
Fig. 168.—Stone Implement (1⁄2).
Oval implement with two hollowed surfaces.—This is a smooth oval-shaped stone with a wrought, circular, and cup-shaped depression on each side. Its length is 31⁄4 inches, breadth 25⁄8, and thickness 1 inch. The largest diameter of the depression is 15⁄8 inch, and its greatest depth 1⁄2 an inch. It is made of a hard grey trap rock, and, though well wrought all over, is not polished, nor does it exhibit any markings such as are seen on the ordinary hammer-stones, (Fig. 168). See page [56].
Flint Scrapers.—Of these there are two. One, coarsely chipped out of a dark flint, is here figured (Fig. 169). It is roughly circular in shape, and about two inches in diameter. The other is a chip made by a single blow from the outside of a whitened nodule, and is only 3⁄4 of an inch in diameter.
