As the man spoke, he whipped out and opened his keen-bladed Spanish knife, and, getting flat down on his chest to have his arms at liberty, he reached out the point of his knife like a bayonet.

“Take care, Shaddy,” cried Rob hoarsely, as, knife in hand and holding on by the nearest bough, he peered forward too.

“Trust me, sir. Perhaps if I can get first dig at him before he claws me, he may sheer off. Ah, mind, sir! you’ll have me off. Oh! it’s you, is it?”

The first was a fierce shout of warning, but the second was in a tone of satisfaction.

“I thought it was you come down on my back,” growled Shaddy; “but this is as it should be. You never know who’s going to help you at a pinch.”

For without warning the puma had silently made one bound from its perch, and alighted upon the flattish surface presented by the old sailor’s back. Then planting itself with outstretched paws firmly on his shoulders, and lowering its head, it opened its jaws and uttered a savage yell, which was answered from the golden-spangled water where the new-comer was swimming.

“It is a tiger, and no mistake,” said Shaddy in a low voice; “and we’d better let our lion do the fighting, so long as they don’t claw me. Mind, old fellow! That’s right. I’ve got fast hold now.”

As he was speaking he took a firm grip of a bough by his side, and with breathless suspense Rob and Brazier waited for the next phase in the exciting episode, for they were in momentary expectation of the jaguar, if such it was, reaching the tree, climbing up, and a fierce battle between the two savage creatures ensuing, with a result fatal to their companion, unless in the darkness, while they were engaged in a deadly struggle, he could contrive to direct a fatal blow at the bigger and fiercer beast.

They could now dimly make out its shape as it swam to and fro, hesitating about coming up; for the puma, generally so quiet, gentle and docile, had now suddenly become a furious snarling and hissing creature, with its ears flat to its head and paw raised ready to strike.

“I don’t know what’s going to happen next,” said Shaddy in a low voice, “for this is something new to me. I did think I’d gone through pretty well everything; but being made into a platform for a lion and a tiger to fight out a battle’s quite fresh. Suppose you gentlemen get your knives out over my head, so as to try and guard it a bit. Never mind the lion; he won’t touch you while that thing’s in front of him. He can’t think of anything else. I can’t do anything but hold on. That’s right, messmate,” he cried, as the puma made a stroke downward with one paw. “You’ll do the business better than I shall.”
