Lightfoot was not much in the cave now. She lingered about the open space or wandered in the near wood. A woman's instinct told her to be out-doors all the time she could. A man would seek her, but with the thought came an awful dread. Which man? One afternoon she saw something. Two gray forms flitted across an open space in the forest near the cave, and in a moment the girl was in a treetop. What followed was the unexpected. Close behind the gray things came a man, fully armed, straight, eager and alert and silent in his wood surroundings, with eyes roving over and searching all the open space about the cave of Hilltop. The man was Ab. The girl gave a shriek of delight, then, alarmed at the sound she had made, cowered behind a refuge of leaves and branches. She was happy beyond all her experience before. The question which had been in all her thoughts was answered! It was Oak, not Ab, who lay in the ground on the hillside. And, even as she realized this fully, there was a swift upward scramble and the young cave man was beside her on the limb. There was no running away this time. The girl's face told its story well enough, so well that Ab, still lately doubting, though resolved, knew that his fitting mate belonged to him. There came to them the happiness which ever comes to lovers, be they man or bird or beast, and then came swift conclusion. He told her she must go with him at once, told her of the new cave and of all he had done, but the girl, well aware of the dangers of the beast-haunted region where the new home had been selected, was thoroughly alarmed. Then Ab told her of the little flying spears which Old Mok had made for him, and about the wonderful bow which sent them to their mark, and the girl was reassured and soon began to feel exceedingly brave and proud of her lover and his prowess. No need of carrying off a girl by force or craft on this occasion, for Hilltop had fully recognized Ab's strength and quality. The two went to the cave together and there was eating and then, later, two skin-clad human beings, a man and a woman, went away together through the forest. Their journey was a long one and a careful lookout was necessary as they hurried along a pathway of the strange country. But the cave was reached at last, just as the sun burned red and gave a rosy glow to everything. Silently the two came into the open space in front of what was to be their fortress and abode. Solid was the rock about the entrance and narrow the blocked opening. Smoke curled in a pretty spiral upward from where smoldered the fire Ab had made the day before. Lightfoot looked upon it all and laughed joyously, though tremblingly, for she had now given herself to a man and he had brought her to his place of living.
