The hatchet engraved as Fig. 21, was found in ploughing near Bournemouth, and was kindly brought under my notice by the late Mr. Albert Way, F.S.A. Its principal peculiarity is the inward curvature of the sides, rendering it somewhat narrower in the middle than at either end. Its greatest expansion is, however, at what appears to have been intended for the cutting edge, so that at this end its outline much resembles that of one of the Scandinavian forms. The sides, however, instead of being square are sharp. The specimen from Burwell Fen, Fig. 36, exhibits nearly the same form, but has the edge ground. A thinner specimen, also from Burwell Fen, and in the Museum of the Cambridge Antiquarian Society, is unground. It is 5 3∕8 inches long, 2 1∕8 inches broad at one end and 1 1∕2 inches at the other, but only 1 1∕4 inches broad towards the middle of the blade. Mr. T. Layton, F.S.A., possesses a celt found in the Thames, that presents this peculiarity in a still more exaggerated manner. It is 6 3∕4 inches long, 2 3∕4 inches broad at one end and 2 1∕4 inches at the other, but only 1 1∕2 inches in width at the middle of the blade. [Illustration: Fig. 21.—Near Bournemouth. 1∕2] [Illustration: Fig. 22.—Thetford. 1∕2] A remarkably elegant specimen of similar character is shown in Fig. 22. It was found on the surface at Thetford Warren, Suffolk, and was formerly in the collection of Mr. J. W. Flower, F.G.S., but |75| now in mine. It is of grey flint, and has been formed from a large flake, a considerable portion of the flat face of which has been left untouched by the subsequent working. All along the sides, however, as well as at the ends, it has been chipped on both faces to a symmetrical form. The outer surface of the original flake has almost entirely disappeared during the process of manufacturing the adze, for such it appears to have been rather than an axe. The form is suggestive of the tool having been copied from one in metal, and is very like that of the flat bronze celts. It may belong to the transitional period, when bronze was coming into use, but was still too scarce to have superseded flint. The commonest form of the symmetrically-chipped but unground celts is that shown in Fig. 23. The particular specimen engraved is in my own collection; and, like so many other antiquities of this class, came from the Fen district, having been found in Reach Fen in 1852. It is equally convex on both faces, and, from its close resemblance in form to so many of the polished celts, it was probably destined for grinding. I have another of the same form, 6 1∕2 inches long, from the neighbourhood of Thetford. A magnificent specimen of this class, but wider in proportion to its length, found near Mildenhall, is preserved in the Christy Collection. [Illustration: Fig. 23.—Reach Fen, Cambridge. 1∕2]
