Show THE CATARACTS OF THE ORINOCO. IN the preceding section, which was made the subject of an academical lecture, I sought to depict those boundless plains which, . according to the varying modification of their natural characters induced by climatic relations, appear to us sometimes as Deserts devoid of vegetation, and sometimes as Steppes, or widely-extended grassy plains or Prairies. In so doing, I contrasted the Llanos of the southern part of the New Continent with the dreadful seas of sand which form the African Deserts; and these again with the Steppes of Central Asia, the habitation of world-assailing pastoral nations, who, at a former period, when pressed hitherward from the East, spread barbarism and devastation over the earth. If on that occasion (in 1806) I ventured to combine widely-distributed portions of the earth's surface in a single picture of nature, and to entertain a public assembly with images whose coloring was in unison with the mournful disposition of our minds at that epoch, I will now, limiting myself to a narrower circle of phenomena, sketch the more cheerful picture of river scenery, composed of foaming rapids and rich, luxuriant vegetation. I propose to describe in particular two scenes of nature in the wilderness of Guiana-the celebrated Cataracts of the Orinoco, Atures and lHaypures-which, previous to my visit, few Europeans had ever seen. The impression left on our minds by the aspect of nature is frequently determined, less even by the peculiar character of the strictly terrestrial portion of the scene, than by the light thrown on mountain or plain, either by a sky of azure purity, or by one veiled by lowering clouds; and in the same manner descriptions of nature act upon us more powerfully or more feebly, according as they are more 15 |
