Continuing their march, the country now spread out into broad savannas terminated by forests, which, as they drew near, seemed to stretch on every side to the very verge of the horizon. Here they beheld trees of that stupendous growth seen only in the equinoctial regions. Some were so large, that sixteen men could hardly encompass them with extended arms! 4 The wood was thickly matted with creepers and parasitical vines, which hung in gaudy-colored festoons from tree to tree, clothing them in a drapery beautiful to the eye, but forming an impenetrable network. At every step of their way, they were obliged to hew open a passage with their axes, while their garments, rotting from the effects of the drenching rains to which they had been exposed, caught in every bush and bramble, and hung about them in shreds.5 Their provisions, spoiled by the weather, had long since failed, and the live stock which they had taken with them had either been consumed or made their escape in the woods and mountain passes. They had set out with nearly a thousand dogs, many of them of the ferocious breed used in hunting down the unfortunate natives. These they now gladly killed, but their miserable carcasses furnished a lean banquet for the famishing travellers;and, when these were gone, they had only such herbs and dangerous roots as they could gather in the forest.6At length the way-worn company came on a broad expanse of water formed by the Napo, one of the great tributaries of the Amazon, and which, though only a third or fourth rate river in America, would pass for one of the first magnitude in the Old World. The sight gladdened their hearts, as, by winding along its banks, they hoped to find a safer and more practicable route. After traversing its borders for a considerable distance, closely beset with thickets which it taxed their strength to the utmost to overcome, Gonzalo and his party came within hearing of a rushing noise that sounded like subterranean thunder. The river, lashed into fury, tumbled along over rapids with frightful velocity, and conducted them to the brink of a magnificent cataract, which, to their wondering fancies, rushed down in one vast volume of foam to the depth of twelve hundred feet! 7 The appalling sounds which they had heard for the distance of six leagues were rendered yet more oppressive to the spirits by the gloomy stillness of the surrounding forests. The rude warriors were filled with sentiments of awe. Not a bark dimpled the waters. No living thing was to be seen but the wild tenants of the wilderness, the unwieldy boa, and the loathsome alligator basking on the borders of the stream. The trees towering in wide-spread magnificence towards the heavens, the river rolling on in its rocky bed as it had rolled for ages, the solitude and silence of the scene, broken only by the hoarse fall of waters, or the faint rustling of the woods,--all seemed to spread out around them in the same wild and primitive state as when they came from the hands of the Creator.
