I have seen a flake about 3 inches long, with the edge ground, that had been found on the top of the cliffs at Bournemouth; and another, from a barrow near Stonehenge, in the possession of the late Mr. Frank Buckland. A flat flake, with a semicircular end, and ground at the edges so as to form “a beautiful thin ovoidal knife three and a half inches long,” was found by Dr. Thurnam,[1303] with many other worked flints, in the chambered long barrow at West Kennet, Wilts. Another, carefully ground at one edge, was found by Sir R. Colt Hoare,[1304] at Everley. An oval knife, about 2 inches long, ground at the edge and over a great part of the convex face, found at Micheldean, Gloucestershire, is in the museum at Truro. A cutting instrument, with a very keen edge, nicely polished, is recorded as having been found, with twenty other flint implements or tools of various shapes, accompanying a skeleton, in a barrow near Pickering.[1305] A so-called spear-head, neatly chipped and rubbed, was found with burnt bones in another barrow near the same place.[1306] A few flat flakes, ground at the edge, have been discovered in Scotland. One 2 1∕2 inches long was found at Cromar,[1307] Aberdeenshire; and a portion of another in a cairn in Caithness,[1308] in company with a polished perforated hammer and other objects. Irish flakes are rarely sharpened by grinding. I have, however, one of Lydian stone,[1309] found in Lough Neagh, and ground to an edge at the end. In form the Charleston flake, Fig. 196, much resembles some of the Swiss flakes, which, from examples that have been found in the |292| Lake-dwellings, are proved to have been mounted in handles. One of these, from Nussdorf, in the Ueberlinger See,[1310] is in my own collection, and is shown in Fig. 197. It is fastened into a yew-wood handle by an apparently bituminous cement. The edge has been formed by secondary chipping on the ridged face of the flake. I am unable to say whether the edge of the flake still embedded in the wood is left as originally produced or no, but several unmounted flakes from the same locality have been re-chipped on both edges. In some instances, however, only one edge is thus worked. In the case of many of the small narrow flakes from the Dordogne caves, one edge is much worn away, and the other as sharp as ever, as if it had been protected by being inserted in a wooden handle.
