Suddenly, from out of the sea, appeared a series of human heads, and then a band of men and women that waded ashore and seated themselves upon the beach, gazing restlessly out across the sea. This was not the same band I had seen at first. These were a slimmer race, and whereas the first band had been exceedingly swarthy, these were very fair. They did not stay long on shore, for they were restless and ill at ease. It seemed to me they came there only from force of habit, as though they obeyed some inner urge they did not understand. In a few seconds they rose and ran into the water, plunged into it as though they welcomed its embrace, and disappeared. Then again the vision was swallowed up by the swirling mists of time. * * * * * When the scene cleared again, it showed the bottom of the sea. A group of perhaps a hundred pale creatures moved along the dim floor of the ocean. Ahead I could see the dim outlines of one of their strange cities. The band approached, seemed to talk with those there, and moved on. I saw them capture and kill fish for food, saw them carve the thick, spongy hearts from certain giant growths and eat them. I saw a pair of killer sharks swoop down on the band, and the quick, deadly accuracy with which both men and woman met the attack. One man, older than the rest, was injured before the sharks were vanquished, and when their efforts to staunch his wounds proved unavailing, they left him there and moved on. And as they left I saw a dim, crawling shape move closer, throw out a long, whiplike tentacle, and wrap the body in a hungry embrace. They came to and passed other communities of beings like themselves, and a city of their own, in much the way that Mercer had visualized it. Fading, the scene changed to the interior of the coral house again. The old man finished his story, and moved off into a cubicle in the rear of the place. Dimly, I could see there a low couch, piled high with soft marine growths. Then the scene shifted once more. A man and a woman hurried up and down the narrow streets of the strange city the girl had pictured when she showed us how she had met with the shark, and struck her head, so that for a long period she lost consciousness and was washed ashore. * * * * * Others, after a time, joined them in their search, which spread out to the floor of the ocean, away from the dwellings. One party came to the gaunt skeleton of the ancient wreck, and found the scattered, fresh-picked bones of the shark the girl had killed. The man and the woman came up, and I looked closely into their faces. The woman's features were torn with grief; the man's lips were set tight with suffering. Here, it was easy to guess, were the mother and the father of the girl.
