The unwary beasts rose and sank not many feet from the canoe for the last time while they were abreast of the canoe; and, at the word given by Kalulu, Simba and Moto dipped their paddles, and sent the boat into the stream bow forward, the harpooneer entrusted with the duty of striking standing rigid with uplifted weapon, ready for the blow.
A minute thus he stood, and all eyes were fixed expectant, when at the bow rose the monstrous head and neck of a bull hippopotamus, and at the same moment the harpoon was shot straight and deep into his neck, while the bright blood gushed upward in streams. The stricken animal sounded immediately, while the water was lashed into foam by his struggles, and soon the canoe was moving up the river at terrific speed, while the water rose in high, brown waves at the bow. Presently the speed slackened, and the canoe began to float down the stream.
“Pull back! pull back!” shouted the harpooneer, and at the same time he tossed the buoyant gourd, to which he had fastened the end of the rope hitherto attached to the boat by a round turn around a cleat, into the water. Responsive to the cry, Simba and Moto dashed their paddles into the water; but they were too late, for they felt the boat lifted up bodily out of the water, and the crew, losing their equilibrium, staggered on one side, which completely turned the canoe over, and precipitated them into the water.
The three boys, Kalulu, Selim, and Abdullah, instinctively, as they felt the canoe lifted out of the water, rose to their feet with their guns in their hands, and when it was assumed beyond doubt that it would turn over, sprang into the water in different directions, and dived to the bottom, dragging themselves toward their island beneath, by clutching the tenacious mud. For some time the wounded hippopotamus remained master of the field, and no enemy appearing in sight, he sank, uttering a horrible bellow as he disappeared out of sight.
Immediately after, Selim appeared above the surface, more than twenty yards from the scene of the disaster, and swimming vigorously towards the island, which he soon gained in safety. Then appeared Abdullah, about ten yards from the bank; Kalulu close to the shore, with Simba, and Moto, and the two warriors close to him. In a second they stood on the shore, Kalulu minus his gun, but having his sharp spear in his hand; the two warriors had also retained their spears, while Simba and Moto had their guns in their hands, and their long broad knives in their waists.
As soon as they had regained the shore, and stood on dry land, the party began to cheer the youthful straggler, Abdullah, and to encourage him to greater exertions. He was within five yards of the bank, and Simba and Moto were already stretching their guns to him to grasp, when suddenly Abdullah’s smiling face assumed a look of terror, and a wild, thrilling shriek was uttered by him, which was silenced instantly by the brown waters closing over his head; and the calm, placid river flowed on, and no swimmer was seen disturbing its surface.
For the shortest possible instant, all hands seemed turned into stone; not a sound nor a breath was heard, until Kalulu was heard uttering the terrible and awful word, “mamba!”—crocodile.
Simba and Moto then breathed, and confused murmurs were heard from all. “Save him!” cried Selim; “oh, save poor Abdullah!”
There was no need to utter the prayer; for young Kalulu had divested himself of his wet loin-cloth, had broken the staff of the spear he held short off, close to the sharp head, and with the latter grasped firmly in his hand, had plunged head-foremost, unconscious, as it were, of the imminent danger of the hazardous undertaking, into the water, where Abdullah was last seen.
