Interruptions in this world of uncertainty are not uncommon, and in the African wilds they are peculiarly frequent. The interruption which occurred on the present occasion to Dr Hopley’s reply was, we need scarcely remark, exceedingly opportune. It came in the form of a hippopotamus, which rose so close to the boat that Ailie got a severe start, and Tim Rokens made a blow at its head with his paddle. It did not seem to notice the boat, but after blowing a quantity of water from its nostrils, and opening its horrible mouth as if it were yawning, it slowly sank again into the flood.

“Wot an ’orrible crittur!” exclaimed Jim Scroggles, in amazement at the sight.

“The howdacious willain!” remarked Rokens.

“Is that another on ahead?” said Glynn, pointing to an object floating on the water about a hundred yards up the river: for they had passed the lake, and were now ascending another stream. “D’ye see it, Ailie? Look!”

The object sank as he spoke, and Ailie looked round just in time to see the tail of a crocodile flop the water and follow its owner to the depths below.

“Oh! oh!” exclaimed Ailie, with one of those peculiar intonations that told Glynn she saw something very beautiful, and that induced the remainder of the crew to rest on their paddles, and turn their eyes in the direction indicated.

They did not require to ask what she saw, for the child’s finger directed their eyes to a spot on the bank of the river, where, under the shadow of a spreading bush with gigantic leaves, stood a lovely little gazelle. The graceful creature had trotted down to the stream to drink, and did not observe the canoe, which had been on the point of rounding a bank that jutted out into the river where its progress was checked. The gazelle paused a moment, looked round to satisfy itself that no enemy was near, and then put its lips to the water.

Alas! for the timid little thing! There were enemies near it and round it in all directions. There were leopards and serpents of the largest size in the woods, and man upon the river—although on this occasion it chanced that most of the men who gazed in admiration at its pretty form were friends. But its worst enemy, a crocodile, was lurking close under the mud-bank at its feet.

Scarcely had its parched lips reached the stream when a black snout darted from the water, and the next instant the gazelle was struggling in the crocodile’s jaws. A cry of horror burst from the men in the boat, and every man seized a musket; but before an aim could be taken the struggle was over; the monster had dived with its prey, and nothing but a few streaks of red foam floated on the troubled water.

Ailie did not move. She stood with her hands tightly clasped and her eyes starting almost out of their sockets. At last her feelings found vent. She threw her arms round her father’s neck, and burying her face in his bosom, burst into a passionate flood of tears.
