Chebron and Amuba now took their places on the two rafts; and the men, laying down the spears and taking the poles, pushed off from the shore. Noiselessly they made their way among the rushes. Sometimes the channels were so narrow that the reeds almost brushed the rafts on both sides; then they opened out into wide pools, and here the water deepened so much that the poles could scarce touch the bottom. Not a word was spoken, as the men had warned them that the slightest noise would scare the hippopotami and cause them to sink to the bottom of the pools, where they would be difficult to capture. After half an hour’s poling they reached a pool larger than any that they had hitherto passed, and extending on one side almost to the bank of the river. The man on his raft now signed to Chebron to take up one of the spears; but the lad shook his head and motioned to him to undertake the attack, for he felt that, ignorant as he was of the habits of the animal, it would be folly for him to engage in such an adventure. The man nodded, for he had indeed been doubting as to the course which the affair would take, for it needed a thrust with a very powerful arm to drive the spear through the thick hide of the hippopotamus. Amuba imitated Chebron’s example, preferring to be a spectator instead of an actor in this unknown sport. For three or four minutes the boats lay motionless, then a blowing sound was heard, and the boatman pointed to what seemed to the boys two lumps of black mud projecting an inch or two above the water near the margin of the rushes. They could not have believed that these formed part of an animal but that slight ripples widening out on the glassy water showed that there had been a movement at the spot indicated. With a noiseless push Chebron’s hunter sent the boat in that direction, and then handed the end of the pole to Chebron, signing to him to push the boat back when he gave the signal. When within ten yards of the two little black patches there was a sudden movement; they widened into an enormous head, and a huge beast rose to his feet, startled at the discovery he had just made that men were close at hand. In an instant the hunter hurled his spear with all his force. Tough as was the animal’s hide, the sharp head cut its way through. With a roar the beast plunged into the rushes, the shaft of the spear falling out of its socket as it did so, and the strong cord ran out rapidly from the reel held by the hunter. Presently the strain ceased. “He has laid down again in shelter,” the hunter said; “we will now follow him and give him a second spear.” Pushing the rushes aside the boat was forced along until they again caught sight of the hippopotamus, that was standing up to its belly in water. “Is he going to charge?” Chebron asked, grasping a spear.
