A round hammer (2 1∕2-inches), with depressions on each face, was found at Gatley,[921] Cheshire. Hammer-stones of the same character occurred abundantly on the site of ancient Naukratis.[922] The _wallong_,[923] or stone used by the Australian natives for grinding nardoo seeds on the _yow wi_, a large flat stone, is curiously like Fig. 164. [Illustration: Fig. 165.—Bridlington. 1∕2] To the same class, belongs the hammer-stone shown in Fig. 165, found at Huntow, near Bridlington. It has been made from a quartz pebble, of the original surface of which but little remains, and has a |244| well-marked depression about 1∕8 inch deep in the centre of each face. The periphery is much worn away by use. A fine-grained sandstone pebble, in form like a small cheese, about 3 inches in diameter, having the two faces smooth and perfectly flat, was found at Red Hill,[924] near Reigate, and was regarded as a muller or pounding-stone used possibly in husking or bruising grain; or even for chipping flint, its surface bearing the mark of long-continued use as a pestle or hammer.[925] “Precisely similar objects have been found in Northumberland, and other parts of England.” Canon Greenwell informs me that about twenty such, differing in size and thickness, were found on Corbridge Fell, together with several stone balls. He thinks they may possibly have been used in some game. A paper on the stone hammer and its various uses has been published by Mr. J. D. McGuire.[926] The circular stone from Upton Lovel Barrow,[927] engraved by Sir R. Colt Hoare, appears to be a hammer or, more probably, a rubbing-stone, but it is worn to a ridge all round the periphery. I have a precisely similar instrument from Ireland. Other mullers from Wiltshire[928] barrows have been figured by Dr. Thurnam. Several such discoidal stones, somewhat faceted on their periphery, were found by the late Hon. W. O. Stanley, in his examination of the ancient circular habitations in Holyhead Island, and some have been engraved.[929] An almost spherical stone, but flattened above and below, where the surface is slightly polished, was found in Whittington Wood, Gloucestershire, and exhibited to the Society of Antiquaries in 1866.[930] It is of quartzite, about 3 inches in diameter. Another, of the same size, of depressed, spherical form, was found in Denbighshire,[931] and another flat disc of quartz in Aberdeenshire.[932]
