These primeval people built no houses. They lived in natural caves, and scattered the remains of their food about the floor, so that we know what they ate. Among the animals they used for food were the horse, the reindeer, the ox, the cave-lion and bear, the wolf, the hyena, the goat, the hare and several others, besides salmon and other fish. They were very fond of the marrow of the bones, which they cracked with stone hammers, and had little spoons made of bone with which to pick it out. They had places for making flint weapons too. At Cissbury Camp, near Worthing, there is one of their old workshops. There are galleries dug into the chalk where they got the flints, and there are thousands of chips of flint lying about, with half finished arrow-heads, and some of the tools they dug with. They had no spades or pickaxes; but they used the broad, flat, shoulder-blade bone of the ox as a spade, and the sharp brow antler of a deer’s horn for a pickaxe, to get these flints out with. It must have been very hard work for them, because bone spades and horn pickaxes would soon wear out, and would not be nearly so useful as ours made of iron. [Illustration: XI. _Picture of Mammoth Scratched on Ivory._ _Fight between Reindeer Scratched on Slate._] It is difficult to be certain how these stone-age people cooked their food. Of course they could have roasted it, and the half-burnt bones in some caves show that they did so; but in some caves in France there is not a single burnt bone to be found. In these French cave dwellings, too, there are no pieces of earthenware, as there are in some others; so that the people could not have boiled it, unless they had wooden pots and dropped red-hot stones into the water in them until the meat got boiled, as some savages do now. Or they might have cooked it under the hot ashes. The people who used earthenware must have made more progress. It is easy to understand how they made this useful discovery. Suppose they had lighted a fire upon a damp clay soil, the earth would get baked hard and crack off in pieces, and they would see that this soil could be worked in the hands while soft into the shape of pans and dishes, which could be dried quite hard in the sun or baked in hot ashes, just as boys make clay marbles now. They could live much more comfortably even with these rough earthenware things, and cook their food more conveniently; but they still used the stone and flint tools and weapons, and iron was still unknown to them.
