Others from Portpatrick[834] (6 3∕4 inches), and from a cist at Cleugh,[835] Glenbervie, Kincardineshire, have been figured. I have a disc (3 inches), nearly flat round the circumference like a Danish “child’s |231| wheel” from Ballachulish, Inverness. It is formed of hornblendic gneiss. A hammer-stone of this kind from Poyanne, Landes,[836] has been recorded. Some of these circular pebbles may have formed the heads of war-maces, such as seem to have been in use in Denmark in ancient times and in a modified form, among various savage tribes in recent days. A curious variety of this type, flat on one face and convex on the other, is shown in Fig. 158. It is made from a quartzite pebble, that has in some manner been split, and was found at Sutton, near Woodbridge. It is now in the collection of General Pitt Rivers, F.R.S. [Illustration: Fig. 158.—Sutton. 1∕2] In the Christy Collection is another implement of much the same size, material, and character, which was found at Narford, Norfolk. The ends are somewhat hollowed after the manner of a gouge, but the edges are rounded. It seems to occupy a sort of intermediate position between a hammer and an adze. One of similar, but more elongated form, found at Auquemesnil[837] (Seine Inférieure), has been figured by the Abbé Cochet. It is difficult to say for what purpose hammers of this perforated kind were destined. I can hardly think that such an enormous amount of labour would have been bestowed in piercing them, if they had merely been intended to serve in the manufacture of other stone implements, a service in which they would certainly be soon broken. If they were not intended for weapons of war or the chase, they were probably used for lighter work than chipping other stones; and yet the bruising at the ends, so apparent on many of them, betokens their having seen hard service. We have little, in the customs of modern savages, to guide us as to their probable uses, as perforated hammers are almost unknown among them. The perforated spheroidal stones of Southern Africa[838] act merely as weights to give impetus to the digging sticks, and such stones are said to have been in use in Chili[839] and California.[840] The perforated discs of North America appear to be the fly-wheels of drilling sticks. Some quartz pebbles perforated with small central holes, and brought from the African Gold Coast,[841] seem to have been worn as charms. |232|
