Whetstones.—These are also numerous, but it is difficult to draw a minute distinction between them and the polishers. They vary in length from 21⁄2 to 61⁄2 inches, and are mostly composed of hard claystone or indurated sandstone. One of them, judging from the only fragment which was found, was manufactured with great care, and had a small hole at one end for suspension. This fragment, which is here figured (Fig. [162]), measures 31⁄2 inches long, 2 broad, and half an inch thick.

Another is made of fine-grained sandstone, and shaped precisely similar to the sharpening-stones now used for scythes. Its dimensions are 51⁄2 inches long, 3⁄4 inch broad, and 1⁄2 inch deep (Fig. [163]).
Funnel-shaped Holes.—Three flat portions of sandstone, each containing a small hole, opening up on both sides into funnel-like cavities. The stone here engraved is roughly circular, about 4 inches in diameter and 1 inch thick. The cavity at its mouth is about 1 inch in diameter, 1⁄2 an inch deep, and communicates with a similar one on the other side by a hole through which a small goose-quill can just pass. The holes in the other stones are precisely similar in shape, only the mouth of the funnel in one is one-third larger, and in the other about as much less; these differences being entirely dependent on the thickness of the stone (Fig. [164]).
Fig. 164.—Perforated Sandstone (1⁄2).
Pebbles.—Of these there were several hundreds found, scattered all over the island, varying in size from half an inch to 6 or 7 inches in diameter, the larger of which might have been used as anvils, others as heating-stones, sling-stones, etc.
Querns.—Out of eleven quern-stones, almost all of which were made of granite, only two could be positively stated to be under ones. Three of the upper ones were round coarse lumps, about 1 foot in diameter and 10 inches deep, and of these two appear to have been unfinished. One had merely a cup-shaped cavity on its top, but no hole; and the other, in addition to the cup, had the central hole partially bored from both sides. Neither of them had any marginal hole.
