Down came another bank of water. Gingham had now scarcely standing-room. The water rushed rapidly by him, and I began to fear he might not long have a footing. At this critical moment, the trunk of a tree, with most of its branches broken off, but here and there a small bough still remaining, came right down towards Gingham, shearing, surging on the tumultuous waters, hung for a moment on the shallow, and then began moving on again with the current. Gingham stooped forward to seize it--he did well, it was his only hope--but lost his feet. He threw himself astride the timber, like Waterton on the crocodile's back, and was borne off from the island, still retaining his hold, though turned over and over by the violence of the current. I saw no hope. What could prevent his being carried away? Yet there was still a possibility of escape, though unforeseen. The trunk, carried a few yards down, was caught by an eddy, and swung round into the slack water below, where the current was broken by the bank on which Gingham had just been standing. There the huge log began slowly moving round in a circle, first ascending in a direction opposite to the stream, then descending again. On reaching the lowest point of the circle, the trunk, with Gingham upon it, was again caught by an eddy, and twirled round like a spindle; then, with solemn movement, began gradually to ascend again, describing the same circle as before. This second time, though, in going down, it reached a lower point ere it was again caught and twirled, by which law, it was clear, the third time it would go with the current. Manfully did Gingham still hold on, though so often under water; and now, for the third time, he and his log began slowly to move in an ascending orbit. A third time he reached the highest point; and a third time, to all appearance the last, he began--I often dream of it--to go down with the stream! We had given up all hope. Joaquim stood wringing his hands; Coosey was like a man distracted; even the crippled soldiers would gladly have given their aid, had any devisable expedient presented itself. There was no visible alternative; this time he must be carried away!--What's that? Something stirred at my feet! I looked down. There was again a little movement. The rope twitched, as if beginning to run out! My foot was on it, in an instant. The next, I and Coosey held it fast. The tree, in moving round and round, had fished hold, and disengaged it from the catch. "Pull away, pull away!" shouted the soldiers.--"Now run him up to the bank."--"Now's your time."--"Make haste!" "Steady, Coosey, steady," said I. "Take time, or we shall loosen the hitch, perhaps break the rope." We did not pull. We merely held on. The log and Gingham swung to the bank.
