The Landscape Of The Tropics In The Low Regions Of The Continents Has A Peculiar Physiognomy, Something Of Greatness And Repose, Which It Preserves Even Where One Of The Elements Is Struggling With Invincible Obstacles.

Near the equator, hurricanes and tempests belong to islands only, to deserts destitute of plants, and to those spots where parts of the atmosphere repose upon surfaces from which the radiation of heat is very unequal.

The mountain of Manimi forms the eastern limit of a plain which furnishes for the history of vegetation, that is, for its progressive development in bare and desert places, the same phenomena which we have described above in speaking of the raudal of Atures. During the rainy season, the waters heap vegetable earth upon the granitic rock, the bare shelves of which extend horizontally. These islands of mould, decorated with beautiful and odoriferous plants, resemble the blocks of granite covered with flowers, which the inhabitants of the Alps call gardens or courtils, and which pierce the glaciers of Switzerland.

In a place where we had bathed the day before, at the foot of the rock of Manimi, the Indians killed a serpent seven feet and a half long. The Macos called it a camudu. Its back displayed, upon a yellow ground, transverse bands, partly black, and partly inclining to a brown green: under the belly the bands were blue, and united in rhombic spots. This animal, which is not venomous, is said by the natives to attain more than fifteen feet in length. I thought at first, that the camudu was a boa; but I saw with surprise, that the scales beneath the tail were divided into two rows. It was therefore a viper (coluber); perhaps a python of the New Continent: I say perhaps, for great naturalists appear to admit that all the pythons belong to the Old, and all the boas to the New World. As the boa of Pliny was a serpent of Africa and of the south of Europe, it would have been well if the boas of America had been named pythons, and the pythons of India been called boas. The first notions of an enormous reptile capable of seizing man, and even the great quadrupeds, came to us from India and the coast of Guinea. However indifferent names may be, we can scarcely admit the idea, that the hemisphere in which Virgil described the agonies of Laocoon (a fable which the Greeks of Asia borrowed from much more southern nations) does not possess the boa-constrictor. I will not augment the confusion of zoological nomenclature by proposing new changes, and shall confine myself to observing that at least the missionaries and the latinized Indians of the missions, if not the planters of Guiana, clearly distinguish the traga-venados (real boas, with simple anal plates) from the culebras de agua, or water-snakes, like the camudu (pythons with double anal scales). The traga-venados have no transverse bands on the back, but a chain of rhombic or hexagonal spots.
