It seemed to Calvin that it was veering—that it would pass to windward of the island, between him and the dimly seen shore. The thought of losing it was more than he could bear to consider; and with a sudden burst of panic, he threw himself into the waves, beating clumsily and frantically for it.
The river took him into its massive fury. He had forgotten the strength of it. His first dive took him under an incoming wave, and he emerged, gasping, into the trough behind, with water exploding in his face. He kicked and threw his arms about, but the slow and futile-seeming beatings of his limbs appeared helpless as the fluttering of a butterfly in a collector's net. He choked for air, and, rising on the crest of one wave, found himself turned backward to face the island, and being swept past it.
Fear came home to him then. He lashed out, fighting only for the solid ground of the island and his life. His world became a place of foam and fury. He strained for air. He dug for the island. And then, suddenly, he felt himself flung upon hard rock and gasping, crawling, he emerged onto safety.
He hung there on hands and knees, battered and panting. Then the remembrance of the tree cut like a knife to the core of his fear-soaked being. He staggered up, and, looking about, saw that he was almost to the far end of the island. He turned. Above him, at the windward point, the tree itself was just now grounding, branches first, and swinging about as the long trunk, caught by the waves, pulled it around and onward.
With an inarticulate cry, he ran toward it. But the mass of water against the heavy tree trunk was already pulling the branches from their tanglings with the rock. It floated free. Taking the wind once more in its sail of leaves, it moved slowly—and then more swiftly on past the far side of the island.
He scrambled up his side of the island's crest. But when he reached its top and could see the tree again, it was already moving past and out from the island, too swiftly for him to catch it, even if he had been the swimmer he had just proved himself not to be.
He dropped on his knees, there on the island's rocky spine, and watched it fade in the grayness of the rain, until the green of its branches was lost in a grayish blob, and this in the general welter of storm and waves. And suddenly a dark horror of death closed over him, blotting out all the scene.
