A remarkable specimen of an allied kind is shown in Fig. 38A. The edge only is ground and a flat surface has been left at the butt-end, which is almost circular. It was found on Ringwood Gore Farm, East Dean, Sussex, and was given to me by Mr. R. Hilton. Another form, apparently intended for use as an adze, is also of rare occurrence. The specimen shown in Fig. 39 was found at Ganton, Yorkshire, and is in my own collection. It is very much more convex on one face than the other, which, indeed, is nearly flat. The grinding is confined to the edge, but some parts of the flat face are polished as if by friction. The late Dr. John Stuart, F.S.A.Scot., showed me a sketch of a large implement of this type, and considerably bowed longitudinally, found at Bogingarry, Old Deer, Aberdeenshire. It is of flint, 4 1∕2 inches long, and 2 inches wide. |95| [Illustration: Fig. 38A.—East Dean. 1∕2] [Illustration: Fig. 39.—Ganton. 1∕2] [Illustration: Fig. 40.—Swaffham Fen. 1∕2] Another form of adze, if such it be, remarkably flat on one face and narrow at the butt, is shown in Fig. 40. This specimen was found in Swaffham Fen, Cambridge, and is in my own collection. The flat face has been produced at a single blow, and has been left almost untouched, except where trimmed by chipping to form the edge, which, however, |96| has been rendered blunt by grinding. The sides are very minutely chipped along the angles, and there seems some possibility of the instrument having been used as a rimer or boring tool. The celts of other materials than flint, and ground only at the edge, are of rarer occurrence than those in flint. That engraved as Fig. 41 was found at Grindale, near Bridlington. It is of felstone, and is remarkable as being so much curved in the direction of its length. I have another smaller specimen from the same place, but the blade is straight. The edge, however, is slightly gouge-like. Mr. J. W. Brooke has a small adze of flint (2 1∕4 inches) in outline almost identical with Fig. 41. It came from near Aldbourne, Wilts.
