They came at length to a rocky pool. Bill halted, and pointing to an overhanging rock on the other side, drew John's attention to a gentle rippling disturbance of the water. In a moment appeared two red nostrils covered with coarse black hair. John lifted his rifle, but Bill signed to him to wait, and after a few seconds the nostrils sank below the surface: the animal had merely risen to breathe. They all sat down on the bank to await his reappearance. Several times during half-an-hour he showed just as much of himself, and no more. This was tantalizing. Would he never emerge? John's patience at length gave out. He thought that if he could cross to the other side he might get a fair shot at the beast, or at least stir him to movement. Looking down-stream, he saw that some little distance away the surface of the river was broken, which indicated shallow water. He hastened to the spot, and stripping to his shirt, waded across waist deep, climbed the bank, and stealthily crept up until he came directly over the place where the hippo had last appeared.
Scarcely had he arrived there when the beast heaved its great back, with a convulsion of the water, above the surface a little farther up the pool. In an instant the rifle was at his shoulder: he fired; the hippo gave a snort, and the water around him was agitated as by an immense churn. Quick as thought John fired the second barrel: and the beast rolled over on its side, with a bullet through the brain.

The four porters shouted with delight, and plunged into the water to drag the carcase to the bank with the cords they had brought with them. The current, however, carried it downwards, and wedged it between two rocks so tightly that, when they had tied the cords to the feet, all their hauling failed for a time to dislodge it. John was determined to secure the prey, which would provide two days' food for his whole party, so he stripped off his sole remaining garment and, first spying for crocodiles, swam to the assistance of the men. After ten minutes' hauling the unwieldy body was freed from the detaining rocks and drawn slowly to the bank.
