On the top of one of them—that nearest the water’s edge—a dark object was visible. It was plainly the body of some animal, but what sort it was, I could not tell, nor could Joao, as it lay stretched along the log.

There was a back, and shoulders, and a neck, head, and legs, too, that appeared to be grasping the trunk on which the animal lay extended. It could not be a piece of dark wood, nor yet a jacare. The outlines of the alligator I should have known at a glance.

“A tapin,” thought I, as Joao had at first suggested; but no, it could not be. Its odd position on the floating log contradicted the supposition of its being a tapin. A capivara! not that either; and none of the species of black monkeys would have lodged themselves so singularly. Besides, it was larger than any of the monkey tribe of these parts.

I thought over every animal that I knew to inhabit the regions of the Amazon. I never once thought of its being a jaguar. Of course the yellow-spotted skin of this monarch of the American forest, I, as well as Joao, would have recognised at a glance.

Both of us gazing and guessing—the tapino still slept—Joao had for the moment forgotten his office of steersman, and we perceived that the igarite was drifting right on to the raft.

The pilot instantly seized the stern oar, and with a strong pull, headed the vessel so as to clear the timber.

We were now nearly opposite, and I at length procured a fair view of the creature that had been puzzling us. What was my astonishment—consternation, I may say—on discovering its true character? Instead of being a harmless tapin, or cavy, as we had been guessing, it was no other than the dreaded janarit pixuna—the black jaguar of the Amazon.

My first thoughts were about my gun, which I held in my hand. A look at the weapon, and I saw that both barrels were empty!

I now remembered having drawn the charges that morning, for the purpose of wiping the barrels, and I had neglected to reload. It would be too late to do so now. A cold fear crept over me. Except some dull cutlasses for cutting brush, there was not another weapon on board. We were literally defenceless.

My gaze returned to the jaguar. He was asleep! His maroon-coloured body, almost as large as that of an Indian tiger, lay stretched along the raft, glistening in the sun—beautiful, but fearful to behold, especially from our point of view. The remains of a large fish, half devoured, lay close by. No doubt he had caught it, satisfied his hunger, and, yielding to the heat of the noon-day sun, had gone to sleep.
