The crocodile had now managed to get its forepaws on the tree, and in struggling to hoist itself its snout was raised almost upright, exposing the soft underside, the sole part in which it is vulnerable to anything except a very heavy bullet. Samba caught sight of the tip of the snout above the tree; here was the opportunity he had hoped for in making this hazardous experiment. Taking with his left hand a firm grip of a wart on the trunk, he raised himself in the water, and with the right hand drove his spear twice into the monster's throat. The crocodile made no sound; a lash of the powerful tail drove up a wave that caused the tree to rock violently: then the huge body slipped backwards into the water.

The moment he had driven his spear home Samba let go his hold on the tree, and trod water until the current brought the foliage to him. Then he drew himself nimbly up into the branch he had formerly occupied. He was breathless, and scarcely yet recovered from his scare; but there was no sign of the crocodile, and knowing that the reptile when mortally wounded sinks into deep water, he felt that his enemy had gone for ever. He heaved a deep sigh of relief, but chancing to look back, he noticed with a start of renewed dread that the water in the wake of the tree was faintly tinged with red. Was it possible that the crocodile, though wounded, was still following? He felt a shiver thrill through him, and, bending down from his perch, kept his eyes fixed in a stare on that ominous sanguine thread.

The minutes passed. Still the water showed that faint persistent tidge. Samba was becoming more and more nervous. Like the reptile's eyes but a little while ago, that line of red held his gaze in a strange fascination. He was still watching it when the tree suddenly gave a violent lurch, and turned half over. Samba, whose hold had relaxed in his nervousness, was flung off the branch into a clump of bushes at the side of the river, which here began to race rapidly through a deep gorge. Scratched and dazed by the fall he picked himself up slowly. He rubbed his eyes. What was this? He was in the midst of a group of pigmies, who were pointing excitedly, uttering their strange coughing cry, to the branches of the tree. In its lurch it had been turned almost completely round, so that the foliage formerly beneath the water was now uppermost. And there, firmly wedged in a fork of two boughs, lay the lifeless body of the crocodile.

The Bambute jabbered to Samba, stroked his arms, patted his back, examined the spear which, though it was broken in his fall, he had not let go. From the bank they had witnessed the boy's bold fight, and they had followed the course of the floating tree until it ran ashore on a jutting bed of rock. Samba made signs that he wished to pursue his journey on foot; but the Bambute shook their heads and grunted and carried him away with them. Once more he was a prisoner.

Bula Matadi comes to Ilola

"Well, Barney," said Jack, when Mr. Martindale's canoe had disappeared, "I don't know how a first mate would feel if he lost his captain in mid-ocean, but I should fancy he'd feel pretty much as I do now."

"And what sort of feeling is now consuming ye, sorr?"
