“At all events he may take refuge in a tree, and wait until the animal goes away.”

“It is said this rhinoceros will patiently bore with his sharp horn until he has broken the tree, and then kill the man; that he will work for days until his object be accomplished.”

“See!” exclaimed Dona Isabel; “there are canoes coming up the river. What are they doing?”

There were at that moment four small boats rounding the island, just where the Shire discharged itself into the Zambesi, and their movements seemed eccentric enough to warrant the surprise expressed by Dona Isabel.

Independently of the rowers, one man stood erect in the bow of each canoe, holding in his hand an assegai, which from time to time he threw. As they neared the bank, a huge hippopotamus rose to the surface, and with a shout, the how man in the nearest canoe made his cast. The spear missed; but the second boat dashed up. Again the hippopotamus rose, and this time the assegai struck true.

“Why, it is exactly the way the Arctic seamen take the whales!” exclaimed Hughes.

A loud scream from Dona Isabel, as she started from her recumbent position, was heard. The hippopotamus had risen again, and with its great red mouth open, dashed in fury at the leading canoe.

The man in the bow seemed paralysed with fear, for he did not make a cast; the next moment the boat was floating bottom upwards, drifting with the stream, but the animal had received another assegai as he was in the act of striking the canoe.

As for its crew, they rose to the surface, and struck out for the bank, vigorously swimming like fishes, their comrades taking no notice of them. The hippopotamus seemed badly hurt now, for it rose again quickly, receiving another lance, and then, dragging itself on to the bank, fell from exhaustion and loss of blood, the natives giving a yell of triumph as they rowed up.

“Listen!” said Wyzinski, “that was a shout; here, down the river bank, to the right.”
