A LESSON IN SWIMMING.

Ab and Oak, ranging far in their hunting expeditions, had, long since, formed the acquaintance of the Shell People, and had even partaken of their hospitality, though there was not much to attract a guest in the abodes of the creek-haunters. Their homes were but small caves, not much more than deep burrows, dug here and there in the banks, above high water mark, and protected from wild beasts by the usual heaped rocks, leaving only a narrow passage. This insured warmth and comparative safety, but the homes lacked the spaciousness of the caves and caverns of the hills, and the food of fish and clams and periwinkles, with flesh and fruit but seldom gained, had little attraction for the occasional cave visitor. Ab and Oak would sometimes traffic with the Shell People, exchanging some creature of the land for a product of the water, but they made brief stay in a locality where the food and odors were not quite to their accustomed taste. Yet the settlement had a slight degree of interest to them. They had noted the buxom quality of some of the Shell maidens, and the two had now attained an age when a bright-eyed young person of the other sex was agreeable to look upon. But there had been no love passages. Neither of the youths was yet so badly stricken.

There came an autumn morning when Ab and Oak, who had met at daybreak, determined to visit the Shell People and go with them upon a fishing expedition. The Shell People often fished from boats, and the boats were excellent. Each consisted of four or five short logs of the most buoyant wood, bound firmly together with tough withes, but the contrivance was more than a simple raft, because, at the bow, it had been hewed to a point, and the logs had been so chosen that each curved upward there. It had been learned that the waves sometimes encountered could so more easily be cleft or overridden. None of these boats could sink, and the man of the time was quite at home in the water. It was fun for the young men whose tale is told here to go with the Shell People and assist in spearing fish or drawing them from the river's depths upon rude hooks, and the Shell People did not object, but were rather proud of the attendance of representatives of the hillside aristocracy.

The morning was one to make men far older than these two most confident and full of life. The season was late, though the river's waters were not yet cold. The mast had already begun to fall and the nuts lay thickly among the leaves. Every morning, and more regularly than it comes now, there was a spread of glistening hoar frost upon the lowlands and the little open lands in the forest and upon every spot not tree-protected. At such times there appeared to the eyes of the cave people the splendor of nature such as we now can hardly comprehend. It came most strikingly in spring and autumn, and was something wonderful. The cave men, probably, did not appreciate it. They were accustomed to it, for it was part of the record of every year. Doubtless there came a greater vigor to them in the keen air of the hoar frost time, doubtless the step of each was made more springy and each man's valor more defined in this choice atmosphere. Temperate, with a wonderful keenness to it, was the climate of the cave region in the valley of the present Thames. Even in the days of the cave men, the Gulf Stream, swinging from the equator in the great warm current already formed, laved the then peninsula as it now laves the British Isles. The climate, as has been told, was almost as equable then as now, but with a certain crispness which was a heritage from the glacial epoch. It was a time to live in, and the two were merry on their journey in the glittering morning.

The young men idled on their way and wasted an hour or two in vain attempts to approach a feeding deer nearly enough for effective spear-throwing. They were late when, after swimming the creek, they reached the Shell village and there learned that the party had already gone. They decided that they might, perhaps, overtake the fishermen, and so, with the hunter's easy lope, started briskly down the river bank. They were not destined to fish that day.

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.

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.
