Fig. 121. Portion of a circular implement, about 8 inches in diameter, and having a round hole in centre and ten small holes along the margin (if the circle were completed at same rate there would be fifteen holes in the series). The central hole was 11⁄4 inch in diameter, and had a tightly-fitting plug when found. The other holes were narrower in the middle, and large enough to admit of a common lead pencil to pass through. They also slanted slightly inwards, so that their axes, if prolonged, would meet at a common point about 6 inches from the central hole, and in the line of its axis.
Fig. 122. Circular wheel, with hole in its centre and pointed teeth at circumference; diameter 31⁄4 inches, ditto of hole 3⁄4 inch, thickness 1⁄2 an inch.

Fig. 123. Smooth piece of wood, 25 inches by 15, with square hole at top and two round ones at sides. Several other portions of boards, containing curious-shaped holes, were found.
