The left bank of the river, which is called Grande Terre, is covered with perpetual verdure, the soil is fertile, and wants only hands to cultivate it.
Opposite, and to the east of St. Louis, is the isle of Sor, which is four or five leagues in circumference; it is of a long and almost triangular form: there are two extensive plains in it, where habitations might be erected. They are covered with grass two metres in height, a certain proof of the advantages that might be derived from the cultivation of this island. Cotton and indigo grow there naturally, the ground is in some parts low and damp, which gives reason to suppose that the sugar-cane would succeed. It might be secured against the inundations which take place in the rainy season, by erecting little causeways a metre in height, at the most. There are in this island, principally on the east side, mangoes, palatuviers, a great quantity of gum trees, or mimosas, and magnificent Baobabs[62].
Let us stop for a moment before this colossus, which, by the enormous diameter to which it attains, has acquired the title of the Elephant of the vegetable kingdom. The Baobab often serves the negroes for a dwelling, the construction of which costs no further trouble than cutting an opening in the side to serve as a door, and taking out the very soft pith which fills the inside of the trunk. The tree, far from being injured by this operation, seems even to derive more vigour from the fire which is lighted in it for the purpose of drying the sap, by carbonising it. In this state it almost always happens, that the bark, instead of forming a ridge at the edge of the wound, as happens with some trees in Europe, continues to grow, and at length covers the whole inside of the tree, generally without any wrinkles, and thus presents the astonishing spectacle of an immense tree recompleated in its organisation, but having the form of an enormous hollow cylinder, or rather of a vast arborescent wall bent into a circular form, and having its sides sufficiently wide asunder to let you enter into the space which it encloses. If casting our eyes on the immense dome of verdure which forms the summit of this rural palace, we see a swarm of birds adorned with the richest colours, sporting in its foliage, such as rollers with a sky-blue plumage, senegallis, of a crimson colour, soui-mangas shining with gold and azure; if, advancing under the vault we find flowers of dazzling whiteness hanging
