She resisted, and they quarrelled, both clutching the stick, jabbering each at the other. Both put forth force to keep the thing that knocked down fruit. But there was actually more strength in his long arms and large hands than in hers. He wrested the stick from her and grinned with delight in its possession.

It is probable that, of late, changes had been occurring among the particles of his own brain. Probably he, too, had been making discoveries. Neither the one nor the other might corner discovery. At any rate, he now began to experiment with the stick. He knocked from the tree all the purple fruit in reach, and then he sat down upon the ground and with the end of the staff scraped at the earth and beat the grass flat. His interest in what he was doing grew and grew. She had gone away, sulking, to the young one. But it was impossible long to resist the fascination of this new extension of power. She came and sat down in the grass and watched. She was friendly again, and he, too, having the stick, was gracious. He was a young, strong, well-looking member of the tree-folk. Lying about were some small stones, miniature boulders. He struck the end of the stick beneath one of these, put his weight upon the other end, and lifted the stone out of its bed. The lever was here. Both of them jabbered with excitement. There were other stones. She wanted to disturb one, too, and she came across and put her hand upon the stick. “Let me!” meant the sound which she uttered. But he jabbered back, and shook her off, and went on turning over stones. Very angry, she returned to the charge, and, watching her chance, suddenly jerked the stick from him. He sprang to his feet and seized it again. She screamed at him and held it stubbornly—a good, thick piece of wood it was! The other kind, now in a violent passion, tugged and wrenched until he got it from her. Then, with suddenness, he found yet another use for a piece of wood. He knocked her down with it, and when, with a cry of fury, she rose to her feet, he repeated the action.

CHAPTER II
THE CAVE

The rocks rose in tiers to a stark height above the dark and tangled wood. From their feet sloped away to the floor of mould a runway of stones great and small. Long ago, long, long ago, water had honeycombed the cliff.

A great stone, shaped like a fir-cone, masked half the cave mouth. A gnarled, rock-clinging tree helped with the other half. When the cave woman had found food and would bring it home, she looked first for the tree and then for the stone.

Sometimes, for a long while, food was easy to get—that is to say, comparatively easy. Then, for a long time, food might be hard to get. There were times when food-getting took strength and cunning and patience in excess. Such was this time, and it had lasted long. So long had it lasted that everything in the world seemed to be hungry.

The cone-shaped stone and the ragged tree kept full sunshine from the cave, but a fair amount entered in shafts and splashes. Four children played in the light and shadow. Naked, with sticks and stones and a snare made from the red fibre of a vine, they played at being hunters. They jumped and dodged and screamed; they hid behind outcropping folds of rock; now one was the quarry and now another. When they tired of that, they sat down and tossed and caught round, shining pebbles, brought to them by the mother from a stream she had crossed. After a time they grew hungry and easily angered. One struck another and they fought. That over, a common void and weakness drew them again together. The sun was getting low, the orange light going away from the littered cavern floor. They felt cold. Back in the cave was heaped dry wood from the floor of the forest, and to one side, guarded by a circle of flat stones, a little fire was burning. Never were the children to burn too great a fire, and never were they to let what was there go out! Now they sat around it whimpering. The oldest crawled into the dimness of the cavern and, bringing back an armful of small sticks, put two crosswise in the flame. Warmth was good, and the flickering light did for sunbeams. Three sat hunched around the fire, while the littlest one lay and sucked its thumb for lack of other food, and went at last to sleep. The next to the littlest nodded, nodded, and then it, too, slept, close to the littlest for warmth. The eldest was a girl and the next a boy. Shag-haired, naked, lean, they watched and fed the fire, and with growing hunger watched the entrance. Daylight grew colder and thinner. They got up and went to the cave mouth. The tree and the cone-shaped rock blocked vision. The lawgiver had forbidden the four to show themselves on the farther side of the tree and the rock. If they did, all the ill of the world would fall upon them. At least, they knew that the lawgiver’s hand would fall upon them.

The two children went back into the cave. In a corner lay a pile of skins—both short hair and thick fur. They took two of these and wrapped themselves in them. The light grew colder and thinner. They were so hungry that tears came out of their eyes. The littlest one waked and cried.

The two eldest wandered again to the cave mouth. They wanted so badly to see if the provider were coming. From the other side of the big stone they could look down the runway of stones, they could see some way into the wood. They stood and stared at the concealing face of the big stone and the concealing, twisted trunk of the tree, and the tears ran down their cheeks. The feet of the eldest one moved uncertainly, then with more assurance. She moved out of the cave mouth and around the great stone, beckoning to the next eldest to follow. He ran after her. Shag-haired, with skins from the heap gathered around them, they came in front of the masking stone and tree. Here the light was stronger, was as yet quite strong.

They looked down the stony slope, and they peered under the thick trees at its base, but nowhere could they see the provider. She had been gone a long time. The world looked cold and harsh and terrifying to the children.... Yet it was hard to go back into the cave, when, if they stayed out here, they might the sooner see the provider. They stayed, two small shapes huddled at the top of the runway of stones.
