The men of the later Stone Age are the ancestors of the civilised men of to-day. Classical antiquity among Greeks and Romans had still a consciousness of this, at least partly; it was not entirely forgotten that the oldest weapons of men did not consist of metal, but of stone, and even inferior material. The worked stones which the people then, as now, designated as weapons of the deity, as lightning-stones or thunderbolts, were recognised by keener-sighted men as weapons of primeval inhabitants of the land. [Sidenote: What the Kitchen Middens Tell Us] The “kitchen middens” on the Danish coasts mark places of more or less permanent settlement, consisting of more or less numerous individual dwellings. From these middens a rich inventory of finds has been made, affording a glimpse of the life and doings of those ancient times. The heaps consist principally of thousands upon thousands of opened shells of oysters, cockles, and other shellfish still eaten at the present day, mingled with the bones of the roe, stag, aurochs, wild boar, beaver, seal, etc. Bones of fishes and birds were also made out, among the latter being the bones of the wild swan and of the now extinct great auk, and, what is specially important in determining the geological age of these remains, large numbers of the bones of the capercailzie. Domestic animals are absent with the exception of the dog, whose bones, however, are broken, burnt, gnawed in the same way as those of the beasts of the chase. Everything proves that on the sites of these middens there formerly lived a race of fishers and hunters, whose chief food consisted of shellfish, the shells of which accumulated in mounds around their dwellings. Proofs of agriculture and cattle-rearing there are none; the dog alone was frequently bred not only as a companion in the chase, but also for its flesh. The state of civilisation of the old Danish shellfish-eaters was not quite a low one in spite of its primitive colouring, and in essential points was superior to that of Palæolithic Man. Not only had they tamed a really domestic animal, the dog, but they made and used clay vessels for cooking and storing purposes. The cooking was done on fireplaces. They could work deer-horn and bone well. Of the former hammer-axes with round holes were made, and of animal bones arrow-heads, awls, and needles, with the points carefully smoothed. Small bone combs appeared to have served not so much for toilet purposes as for dividing animal sinews for making threads, or for dressing the threads in weaving. [Illustration: EUROPE IN THE ICE AGE The map illustrates the extent of the Ice Age in Europe. It will be noticed that in England the ice-cap did not extend south of the position of London though it occurred much further south in the mountain regions of the Pyrenees, the Alps, Tyrol, the Carpathians and the Caucasus. The dark portions of the map represent the extent of the ice. ]
