A long narrow chisel-like celt of this pointed oval section (8 inches) from Aberdeenshire[340] has been figured. A flint celt from Chiriqui,[341] found with a sort of flint punch and some burnishing pebbles in a grave, presumed to be that of one of the native workers in gold, is remarkably like Fig. 46 in form. [Illustration: Fig. 47.—Burradon, Northumberland. 1∕2] In the Fitch Collection is a large thick specimen (9 5∕8 inches) found at Heckingham Common, Norfolk, and a shorter, broader one with a faceted edge, from Pentney. Another of flint (6 1∕2 inches) with the sides much rounded, but with a similar facet at the edge, was found at Histon, Cambs, and belonged to the late Rev. S. Banks. It seems probable that these instruments when first made did not exhibit the facet at the edge, but that it has resulted from repeated grinding as the edge became injured by wear. A celt, apparently of this section, but more truncated at the butt, and with a narrow facet running along the centre of the face, was found in Llangwyllog,[342] Anglesey. It is not of flint but of “white magnesian stone.” Fig. 47 exhibits a beautiful implement of a different character, and of a very rare form, inasmuch as it expands towards the edge. It is of ochreous-coloured flint polished all over, and is in the Greenwell Collection. It was found at Burradon, Northumberland, and in outline much resembles that from Gilmerton, Fig. 76, but this latter has the sides flat and a cutting edge at each end. A celt of similar form, but only 6 1∕2 inches long, found at Cliff Hill, is in the Museum at Leicester. Four flint hatchets, found at Bexley, Kent, seem from the description given of them to be nearly of this type.[343] |104| A few specimens of this form, both unground and ground merely at the edge, have already been mentioned, and specimens engraved, as Figs. 21 and 36. Hatchets expanding towards the edge are of more common occurrence in Denmark than in this country, though even there they are rather rare when the expansion is well-defined. In the British Museum is a magnificent celt of this section, but in outline like Fig. 77. It is ground over nearly the whole of its surface, but the edge at each end has only been chipped out. It is made of some felspathic rock, and is no less than 14 5∕8 inches in length. It was found near Conishead Priory, Lancashire. The next specimens that I shall describe are also principally made of other materials than flint. Fig. 48, in my own collection, is of porphyritic greenstone, and was found at Coton, Cambridgeshire. It is polished all over, equally convex on both faces, and has the sides rather more rounded than most of those of nearly similar section in flint. The butt is rather sharper than the sides. I have an analogous implement, found at Nunnington, Yorkshire, but with the sides straighter and rather more converging towards the butt. Others have been found in the same district.
