The rowers drew in their oars. Their task was done. Iturim and Altisquo stood each in the stern of his boat, and dexterously guided their frail crafts among the black rocks, turning aside from the whirling eddies that threatened to suck them in. Each was anxious to be the first to reach the narrowest and most perilous part of the voyage. [Illustration: THE BOAT RACE.] Iturim shot into this vortex of waters more than a boat’s length ahead of Altisquo. It was impossible now for the latter to pass him. The prize was virtually won. Iturim was full of joy, though the spray from the waves wet him from head to foot, and his canoe often grated against the rocks, or was tossed from side to side. Altisquo saw that the swift rush of waters would now bear his rival over the fall before he could hope to overtake him; and his heart was filled with rage and hate. Suddenly an opportunity presented itself to him. His quick eye saw that he had one chance more. It was a wicked chance, but that did not matter to him. To the left of Iturim’s boat was a whirlpool. The waters swirled furiously around a rock, throwing up blinding sheets of spray. By a sudden movement Altisquo turned the stern of his boat around at the risk of breaking it against the rocks. This brought him into swift collision with the stern of Iturim’s boat, and turned the latter violently around towards the whirlpool, while his own canoe swung into the current, and rushed over the fall, stern foremost. It spun around two or three times after this fearful leap, then darted off bow foremost, and Altisquo was the first man who beached his boat at Toucan Point. Fortunately Iturim’s boat was not quite as near the whirlpool as Altisquo supposed, and did not get drawn into it, as he had hoped. The shock it received sent it violently over the fall, dashing it against a rock, where it was broken to pieces, and the two rowers tumbled out. But they were in comparatively still water, and succeeded in swimming to the shore. But, as Iturim was standing in the stern when the collision took place, he was thrown out of the boat with such violence that he fell into the whirlpool. He clutched fast hold of a projecting rock, but the waters were too strong for him. He could not drag himself out by the slippery rocks, and he would certainly have been sucked under and drowned, but for Simuco. The ape had reached the lower rapid before the boats, and was watching the scene with a lively interest when the fatal collision occurred. He comprehended at once his master’s situation, and, springing quickly from rock to rock, seized Iturim by the hair, and held him with so firm a grip that he was enabled with some difficulty to scramble upon the rock, and was taken off by a boat.
