Three or four miles had been passed and a straight stretch of the river had been attained, at the end of which, a mile away, could be seen the boats of the Shell People, to be lost to sight a moment later as they swept around a bend. But there was something else in sight. Perched comfortably upon a rock, the sides of which were so precipitous that they afforded a foothold only for human beings, was a young woman of the Shell People who had before attracted Ab's attention and something of his admiration. She was fishing diligently. She had been left by the fishing party, to be taken up on their return, because, in the rush of waters about the base of the rock, was a haunt of a small fish esteemed particularly, and because the girl was one of the little tribe's adepts with hook and line She raised her eyes as she heard the patter of footsteps upon the shore, but did not exhibit any alarm when she saw the two young men. The ordinary young woman of the Shell People did not worry when away from land. She could swim like an otter and dive like a loon, and of wild beasts she had no fear when she was thus safely bestowed away from the death-harboring forest. The maiden on the rock was most serene. [Illustration: THE YOUNG MEN CALLED TO HER BUT SHE MADE NO ANSWER. SHE BUT FISHED AWAY DEMURELY] The young men called to her, but she made no answer. She but fished away demurely, from time to time hauling up a flashing finny thing, which she calmly bumped on the rock and then tossed upon the silvery heap, which had already assumed fair dimensions, close behind her. As Ab looked upon the young fisherwoman his interest in her grew rapidly and he was silent, though Oak called out taunting words and asked her if she could not talk. It was not this young woman, but another, who had most pleased Oak among the girls of the Shell People. It was not love yet with Ab, but the maiden interested him. He held no defined wish to carry her away to a new home with him, but there arose a feeling that he wanted to know her better. There might,--he didn't know--be as good wives among the Shell maidens as among the well-running girls of the hills. "I'll swim to the rock!" he said to his companion, and Oak laughed loudly. Short time elapsed between decision and action in those days, and hardly had Ab spoken when he flung his fur covering into the hands of Oak, and, clad only in the clout about his hips, dropped, with a splash, into the water. All this time the girl had been eyeing every motion closely. As the little waves rose laughingly about the man, she descended lightly from her perch and slid into the stream as easily and silently as a beaver might have done. And then began a chase. The girl, finding mid-current swiftly, was a full hundred yards ahead as Ab came fairly in her wake.
