A Story of the Stone Age by H.G. Wells

In the days when Eudena and Ugh-lomi fled from the people of Uya towards the fir-clad mountains of the Weald, across the forests of sweet chestnut and the grass-clad chalkland, and hid themselves at last in the gorge of the river between the chalk cliffs, men were few and their squatting-places far between. The nearest men to them were those of the tribe, a full day's journey down the river, and up the mountains there were none. Man was indeed a newcomer to this part of the world in that ancient time, coming slowly along the rivers, generation after generation, from one squatting-place to another, from the south-westward. And the animals that held the land, the hippopotamus and rhinoceros of the river valleys, the horses of the grass plains, the deer and swine of the woods, the grey apes in the branches, the cattle of the uplands, feared him but little--let alone the mammoths in the mountains and the elephants that came through the land in the summer-time out of the south. For why should they fear him, with but the rough, chipped flints that he had not learnt to haft and which he threw but ill, and the poor spear of sharpened wood, as all the weapons he had against hoof and horn, tooth and claw?

Andoo, the huge cave bear, who lived in the cave up the gorge, had never even seen a man in all his wise and respectable life, until midway through one night, as he was prowling down the gorge along the cliff edge, he saw the glare of Eudena's fire upon the ledge, and Eudena red and shining, and Ugh-lomi, with a gigantic shadow mocking him upon the white cliff, going to and fro, shaking his mane of hair, and waving the axe of stone--the first axe of stone--while he chanted of the killing of Uya. The cave bear was far up the gorge, and he saw the thing slanting-ways and far off. He was so surprised he stood quite still upon the edge, sniffing the novel odour of burning bracken, and wondering whether the dawn was coming up in the wrong place.
