But the glorious verdure around soon made me forget the fair vision; and now, riding on a few paces, now halting at an opening in the forest, I sat drinking in the scene with the feelings of one in a dream.

Then we rode on a hundred yards up an ascent, with the sun full upon us once more, to descend a precipitous path, holding on tightly by the mule, which one expected to slip and hurl one down a gulf at the side; but the descent was safely made, and then we stood gazing at a belt of cultivated ground—the forest and river lying off to our right.

“There is the river path, señors,” said our guide, “straight down. The ground is soft and bad for the mules, and I go back. You will find a gentleman to take you over the great river; but I would look about me; there are little snakes, the great water-boa, and the crocodiles of the river.”

Then saluting us with his half-bred Spanish politeness, our guide stood while we possessed ourselves of our light luggage, and then led off his mules, leaving us to follow the pointed-out direction, which took us down to the swampy bank of a great muddy river flowing gently by us, cutting its way, as it were, through a forest of mighty trees, whose tall stems shot up from the water’s edge. There was a small canoe tethered to a sapling where the path ceased, but no sign of its owner; while half a mile in front, across the river, was an opening in the trees similar to that in which we stood, which was, doubtless, the path we were to pursue.

We stood in deep shadow; but the sun was flashing from the breast of the river as it rolled slowly on, its even surface unbroken save here and there by some water-bird; while in several places what seemed to be rough tree-trunks were floating slowly down with the stream. The great trees were wreathed and festooned to the water’s edge with parasites and vines; and now and then the shrill cry of some parrot rang out, the bird flashing into sight for an instant, and then disappearing amidst the glorious verdure.

“Well, Tom,” I said, “this is different from the old country.”

But he did not reply; and turning, I found him gazing fixedly amongst the swamp herbage, through which was a wet, muddy track, when, following the direction of his gaze and peering into the shade, I became aware of a pair of the most hideous, hateful eyes fixed upon me that I had ever seen. I was heated with walking over the wet ground, and there was a warm, steamy exhalation rising around; but in a moment my tongue became dry and a cold perspiration bedewed my limbs, as, fascinated almost, I stood gazing within six feet of the monster, which now began slowly a retrograde motion till the herbage hid it from our sight. Then there was a loud rustling rush, a splash in the water, and wave after wave proclaimed the size of the beast that had, fortunately for us, declined to attack.

“Whurra!” exclaimed Tom with a shudder. “Say, Mas’r Harry, do newts grow as big as that out here?”

“It was a crocodile, Tom,” I said with a shiver. “And look—look! Why, the river swarms with them!”

“So it does, seemin’ly,” exclaimed Tom as I pointed out the slimy backs of half-a-score of them floating down the stream; for I could see now that they were no trees, while here and there on the muddy bank we could make out a solitary monster basking, open-mouthed, in the sun.
