The form of hammer shown in Fig. 150, may be described as a frustum of a cone with convex ends. The specimen here figured is of quartzite, and was found near Rockland, Norfolk. It is preserved in the Norwich Museum. The hole, as usual with this type, is nearly parallel. The lower half of a similar hammer, but of flint, 2 inches in diameter, and showing one-half of the shaft-hole, which is 5∕8 inch in diameter, is in the British Museum. It came from Grundisburgh, Suffolk. A more conical specimen, tapering from 2 3∕8 inches to 1 7∕8 inches in diameter, and 3 inches long, with a shaft-hole 7∕8 inch in diameter within 3∕4 inch of the top, is in the Greenwell Collection. It is of basalt, and was found at Twisel, in the parish of Norham, Northumberland. [Illustration: Fig. 150.—Rockland. 1∕2] Some rather larger and more cylindrical instruments of analogous form have been obtained in Yorkshire. One such, about 4 inches long, and with a small parallel shaft-hole about 3∕4 inch in diameter, was found with an urn in a barrow at Weapon Ness, and is in the museum at Scarborough. With it was a flint spear-head or javelin-head. It is described as rather kidney-shaped in the _Archæologia_.[784] I have the half of another, made of compact sandstone, and found on the Yorkshire Wolds. The same form occurs in Ireland, but the sides curve inwards and the section is somewhat oval. Sir W. Wilde[785] describes two such of polished gneiss, and a third is engraved in Shirley’s “Account of Farney.”[786] Sir William suggests that such implements were, in all probability, used in metal working, especially in the manufacture of gold and silver. Certainly, in most cases, they can hardly have been destined for any ordinary purposes of savage life, as the labour involved in boring such shaft-holes in quartzite, and especially in |224| flint, must have been immense. It seems quite as probable that these were weapons as tools, and, in that case, we can understand an amount of time and care being bestowed on their preparation such as in modern days we find savages so often lavishing on their warlike accoutrements. Another argument in favour of these being weapons, may be derived from the beauty of the material of which they are sometimes composed. That from Farney is of a light green colour and nicely polished, and one in my own collection, found near Tullamore, King’s County, is formed of a piece of black and white gneissose rock, which must have been selected for its beauty. One in the British Museum from Lough Gur is of black hornblende.
