Nature, ever provident, has scattered with a bounteous hand her gifts in the country of the Orinoco, where the jaguar especially abounds. The savannahs, which are covered with grasses and slender plants, present a surprising luxuriance and diversity of vegetation; piles of granite blocks lie here and there, and, at the margins of the plains, occur deep valleys and ravines, the humid soil of which is covered with arums, heliconias, llianas. The shelves of primitive rocks, scarcely elevated above the plain, are partially covered with lichens and mosses, together with succulent plants and tufts of evergreen shrubs with shining leaves. The horizon is bounded with mountains overgrown with forests of laurels, among which clusters of palms rise to the height of more than a hundred feet, their slender stems supporting tufts of feathery foliage. To the east of Atures other mountains appear, the ridge of which is composed of pointed cliffs, rising like huge pillars above the trees.

When these columnar masses are situated near the Orinoco, flamingoes, herons, and other wading birds perch on their summits, and look like sentinels. In the vicinity of cataracts, the moisture which is diffused in the air, produces a perpetual verdure, and wherever soil has accumulated on the plains, it is adorned by the beautiful shrubs of the mountains.

Such is one view of the picture, but it has its dark side also; those flowing waters, which fertilize the soil, abound with alligators: those charming shrubs and flourishing plants, are the hiding places of deadly serpents; those laurel forests, the favorite lurking spot of the fierce jaguar; while the atmosphere, so clear and lovely, abounds with musquitoes and zancudoes, to such a degree that in the missions of Orinoco, the first questions in the morning when two people meet, are, "How did you find the zancudoes during the night? How are we to-day for the musquitoes?"

It is in the solitude of this wilderness, that the jaguar, stretched out motionless and silent, upon one of the lower branches of the ancient trees, watches for its passing prey; a deer, urged by thirst, is making its way to the river, and approaches the tree where this enemy lies in wait. The jaguar's eyes dilate, the ears are thrown down, and the whole frame becomes flattened against the branch. The deer, all unconscious of danger, draws near, every limb of the jaguar quivers with excitement every fibre is stiffened for the spring; then, with the force of a bow unbent, he darts with a terrific yell upon his prey, seizes it by the back of the neck, a blow is given by his powerful paw, and with broken spine the deer falls lifeless to the earth. The blood is then sucked, and the prey dragged to some favorite haunt, where it is devoured at leisure.

Humboldt surprised a jaguar in his retreat. It was near the Joval, below the mouth of the Cano de la Tigrera, that in the midst of wild and awful scenery, he saw an enormous jaguar stretched beneath the shade of a large mimosa. He had just killed a chiguire, an animal about the size of a pig, which he held with one of his paws, while the vultures were assembled in flocks around. It was curious to observe the mixture of boldness and timidity which these birds exhibited; for although they advanced within two feet of the jaguar, they instantly shrunk back at the least motion he made. In order to observe more clearly their proceedings, the travellers went into their little boat, when the tyrant of the forest withdrew behind the bushes, leaving his victim, upon which the vultures attempted to devour it, but were soon put to flight by the jaguar rushing into the midst of them.

The following night, Humboldt and his party were entertained by a jaguar hunter, half-naked, and as brown as a Zambo, who prided himself on being of the European race; and called his wife and daughter, who were as slightly clothed as himself, Donna Isabella and Donna Manuela. As this aspiring personage had neither home nor hut, he invited the strangers to swing their hammocks near his own between two trees, but, as ill-luck would have it, a thunder storm came on, which wetted them to the skin; but their troubles did not end here, for Donna Isabella's cat had perched on one of the trees, and frightened by the thunderstorm, jumped down upon one of the travellers in his cot; he naturally supposed that he was attacked by a wild beast, and as smart a battle took place between the two, as that celebrated feline engagement of Don Quixotte; the cat, who, perhaps had most reason to consider himself an ill-used personage, at length bolted, but the fears of the gentleman had been excited to such degree, that he could hardly be quieted. The following night was not more propitious to slumber. The party finding no tree convenient, had stuck their oars in the sand, and suspended their hammocks upon them. About eleven, there arose in the immediately adjoining wood, so terrific a noise, that it was impossible to sleep. The Indians distinguished the cries of sapagous, alouates, jaguars, cougars, peccaris, sloths, curassows, paraquas, and other birds, so that there must have been as full a forest chorus as Mr. Hullah himself could desire.

When the jaguars approached the edge of the forest, which they frequently did, a dog belonging to the party began to howl, and seek refuge under their cots. Sometimes, after a long silence, the cry of the jaguars came from the tops of the trees, when it was followed by an outcry among the monkeys. Humboldt supposes the noise thus made by the inhabitants of the forest during the night, to be the effect of some contest that had arisen among them.
