5. Flat Stones Pointed at both Ends.
Two objects of this form, coming from stratum II, represents a new type of implement. They are almost identical in shape. One of them, 1-8604, is shown in fig. 19. They consist of long, flat, quadrangular boulder stones, 3-5/8 and 3-7/8 inches long, with an even width and thickness of 1-5/8 inches. Both ends are simply sharpened to a point, and the broad sides, top and bottom, are shaved off as far as the middle of the stone. In form, the stones are similar to a wooden top of today.
6. Sinker-like Stones.
Stones of this description form a large class, exhibiting, however, great diversities of shape. They all seem to have served the same purpose since most of them show indisputable signs of such usage.
About 18 stones of this kind were found in the mound. As regards their varying form and utility, they may be classed as follows:
I. Spherical and oval stones with a peripheral groove: Fig. 20, 1-8669, shows a spherical stone of this kind, found at a depth of 5 feet in cut A. 1-8534, fig. 21, a fragment of an oval stone with a groove about its largest circumference is from stratum I.
II. Flat boulder stones with notches in the corresponding sides for fastening them: Two of these were found in the upper strata; one, from stratum IV, is shown in figure 22.
