In the Fitch Collection is a finer and more symmetrical specimen of the same kind from North Walsham. It is 7 1∕2 inches long, rather more than 1 inch wide, and 7∕8 inch thick. It is polished nearly all over, both faces are ridged, so that it is almost rhomboidal in section, though the angles are rounded; one face is curved lengthways much more than the other, which is nearly straight. At one end it is ground to a semicircular edge, but at the other it is merely chipped, and still shows part of the original crust of the flint. Another implement of this character, but 11 1∕2 inches long, and 2 7∕8 inches wide in the broadest part, was found at Melbourn,[610] Cambridgeshire, and was in the collection of the late Lord Braybrooke. |174| I have seen another nearly 6 inches long, but little polished, and almost oval in section, which was found at Melton, near Woodbridge, Suffolk. This also is blunt at one end, and ground to a semicircular edge at the other. A fragment of a tool of this class, found near Maidenhead, is in the Geological Museum in Jermyn Street. Another, more roughly chipped out and but partially polished, was found on Mount Harry, near Lewes, and is preserved in the Museum in that town. It is narrow at one end, where it is ground to a sharp edge. The late Mr. H. Durden, of Blandford, had another, found on Iwerne Minster Down, Dorset, 5 1∕2 inches long and 1 1∕4 inches broad, more celt-like in type. One face is more convex than the other; the sides are sharp, and one end is squarer than the other, which comes to a rounded point. In my own collection is one of oval section (5 inches), polished nearly all over, from Burwell Fen, Cambridge; another (4 3∕8 inches), much polished on the surface, is from the Thames at Twickenham. A third, from Quy Fen, Cambridge (4 7∕8 inches), is rather broader in its proportions, and of pointed oval section. A fourth, from Bottisham Fen (4 3∕4 inches), has a narrow segmental edge, and is rounded at the butt, where it is slightly battered. These may perhaps be regarded as chisels. [Illustration: Fig. 108.—Bury St. Edmunds. 1∕2] In the Greenwell Collection is what appears to be a fragment of a chisel, still about 4 inches long, found at Northdale, Bridlington. The same form of implement is found in France. I have a fragment of one which was found by M. Dimpre, of Abbeville, in the old encampment known as the Camp de César, near Pontrémy. In the case of some very similar implements of flint from Scandinavia it is the broad end that is usually sharp, though some are entirely unground. Occasionally these implements occur in this country in the same unpolished condition, like Fig. 108, from the neighbourhood of Bury St. Edmunds. This also presents on the more highly ridged face the same curvature in the direction of its length as is to be observed on the polished specimens, and the pointed end seems the sharper and the better adapted for use.
