In another instant the hippopotamus would have had him in his jaws; but now was the time for the other hunters, whose canoes skimmed over the surface side by side, and before the animal could reach the man in the water, first one and then another spear was hurled, taking effect in its neck.

This took off the monster’s attention for a few moments; just sufficient to enable the owner of the overturned canoe to get ashore, right his boat, pour out all the water, and once more return to the attack.

Meanwhile, the other three canoes had gone into the mêlée, each man sending a spear into the neck or shoulder of the huge hippopotamus whenever he pressed one of the other hunters too hard.

This went on for some time, with the monster growing weaker in his resistance, the plan adopted being to weary him out by constant assault; and all this time the great fellow on the mud point had looked on, giving a fierce grunt now and then, and at times prolonging this grunt into a deafening bellow. He evidently mightily disapproved of what was being done to his fellow; but it did not seem to enter into his brain how he was to help him.

The idea seemed to come at last; for, turning his head towards the king’s canoe, he opened his mouth to its fullest extent displaying the great worn-down tusks, and uttered a tremendous roar, that can only be rendered on paper by a repetition of the words, “Hawgnph! hawgnph!” sent through a huge waterpipe, by the blast of a steam-engine of mighty power.

This done he closed his mouth with a tremendous chop, and rushed into the water and disappeared.

“What a brute!” cried Dick.

“He’s coming right for us, I know,” cried his brother. “You see if he don’t come up close here.”

The king seemed to expect it too, and he gave orders to his men; but before the large canoe could be got under weigh the monster rose quite close to them, opened its huge jaws, its little pig-like eyes glowing with fury, and took a piece out of the canoe.

Half the paddlers leaped overboard in their dread, as the monster opened its huge jaws for a second bite, this time close to where the two boys and the king were seated, the latter seeming paralysed at the imminence of the danger.
