Note 1 — Chapter I · The Stone Age: its Duration and its Place in Time.

The first care of man on his arrival upon the earth was necessarily to make sure of food. Wild berries, acorns, and ephemeral grasses only last for a time, whilst land mollusca and insects, forming but a miserable diet at the best, disappear during the winter. Meat must certainly have been the chief food of prehistoric man; the accumulations of bones of all sorts in the caves and other places inhabited by him leave no doubt on that point. The horse, which in Europe was hunted, killed, and eaten for many centuries before it was domesticated, was an important article of diet, and was supplemented by the aurochs, the stag, the chamois, the wild goat, the boar, the bare, and failing them, the wolf, the fox, and above all the reindeer, which multiplied rapidly in districts suitable to it. The elephant bones picked up on Mount Dol and elsewhere are nearly all those of young animals; and it is probable that they had been killed for food by man. In the Sureau Cave in Belgium,1 in that of Aurignac in France, and Brixham in England, have been found complete skeletons of the Ursus spelæus, which bad evidently been dragged in with the flesh still on them, for all the bones are in their natural position. In other caves, the thorax and the vertebræ of the skeletons were missing; the cave-man, having despatched his victim, bad evidently taken only the more succulent parts into his retreat. Beasts of prey merely gnaw the comparatively tender and spongy tops of the bones, leaving the hard, compact parts untouched. In the caves that were inhabited by man, however, we find the apophyses neglected, whilst the diaphyses are split open. We cannot, therefore, make any mistake on this point, or attribute to the beast of prey what is certainly the work of man.
