He came down a shelving bank to the stream. He had never seen water before. The footing looked good. There were no inequalities of surface. He stepped boldly out on it; and went down, crying with fear, into the embrace of the unknown. It was cold, and he gasped, breathing quickly. The water rushed into his lungs instead of the air that had always accompanied his act of breathing. The suffocation he experienced was like the pang of death. To him it signified death. He had no conscious knowledge of death, but like every animal of the Wild, he possessed the instinct of death. To him it stood as the greatest of hurts. It was the very essence of the unknown; it was the sum of the terrors of the unknown, the one culminating and unthinkable catastrophe that could happen to him, about which he knew nothing and about which he feared everything. He came to the surface, and the sweet air rushed into his open mouth. He did not go down again. Quite as though it had been a long-established custom of his he struck out with all his legs and began to swim. The near bank was a yard away; but he had come up with his back to it, and the first thing his eyes rested upon was the opposite bank, toward which he immediately began to swim. The stream was a small one, but in the pool it widened out to a score of feet. Midway in the passage, the current picked up the cub and swept him downstream. He was caught in the miniature rapid at the bottom of the pool. Here was little chance for swimming. The quiet water had become suddenly angry. Sometimes he was under, sometimes on top. At all times he was in violent motion, now being turned over or around, and again, being smashed against a rock. And with every rock he struck, he yelped. His progress was a series of yelps, from which might have been adduced the number of rocks he encountered. Below the rapid was a second pool, and here, captured by the eddy, he was gently borne to the bank, and as gently deposited on a bed of gravel. He crawled frantically clear of the water and lay down. He had learned some more about the world. Water was not alive. Yet it moved. Also, it looked as solid as the earth, but was without any solidity at all. His conclusion was that things were not always what they appeared to be. The cub’s fear of the unknown was an inherited distrust, and it had now been strengthened by experience. Thenceforth, in the nature of things, he would possess an abiding distrust of appearances. He would have to learn the reality of a thing before he could put his faith into it.
