Not to mention numerous instances recorded by Mr. Bateman, I may cite a flake found in company with a barbed flint arrow-head at |328| the foot of a contracted skeleton in a barrow[1473] at Monkton Down, Avebury, and a “triangular spear-head of stone curiously serrated at the edges,” found with a flint arrow-head and perforated boar’s tusk, in an urn at the foot of a skeleton, in a barrow on Ridgeway Hill,[1474] Dorsetshire. Among the flint implements occurring on the surface of the Yorkshire Wolds and elsewhere, flakes trimmed to a greater or less extent along both edges, and over the convex face, are frequently found. The point as well as the base is often neatly rounded, though the former is sometimes chipped to a sharp angle. There is a considerable difference in the inclination of the edge to the face, it being sometimes at an angle of 60° or upwards, like the edge of some scrapers, at other times acute like a knife-edge. There is so great a range in the dimensions and proportions of this class of instruments that it is almost impossible to figure all the varieties. I have, therefore, contented myself with the selection of a few examples, and will commence with those having the more obtuse edges. [Illustration: Fig. 234.—Yorkshire Wolds. 1∕2] Fig. 234, from the Yorkshire Wolds, is an external flat flake, weathered white, and trimmed all round the face, showing the natural crust of the flint, to a point in form like a Gothic arch. A part of the edge is bruised, but it is impossible to say for what weapon such an instrument was intended. It can hardly have been for a javelin-head, though from the outline it would seem well adapted for such a weapon; for in that case the edge would not have become bruised. It may possibly be an abnormal form of scraper. A nearly similar specimen, but narrower in proportion, was found by the late Lord Londesborough[1475] in a barrow near Driffield, and is described as a spear-head.
