The Great Geologist, Leopold Von Buch, Has Imparted New Interest To These Observations By Examining Whether It Be Not Rather Some Parts Of The Continent Of Scandinavia Which Insensibly Heaves Up.

An analogous supposition was entertained by the inhabitants of Dutch Guiana.) When the coast is so low that the

Level of the soil, at a league within the island, does not change to extent of a few inches, these swellings and diminution of the waters strike the imagination of the inhabitants.

The Cayo bonito (Pretty Rock), which we first visited, fully merits its name from the richness of its vegetation. Everything denotes that it has been long above the surface of the ocean; and the central part of the Cayo is not more depressed than the banks. On a layer of sand and land shells, five to six inches thick, covered by a fragmentary madreporic rock, rises a forest of mangroves (Rhizophora). From their form and foliage they might at a distance be mistaken for laurel trees. The Avicennia, the Batis, some small Euphorbia and grasses, by the intertwining of their roots, fix the moving sands. But the characteristic distinction of the Flora of these coral islands is the magnificent Tournefortia gnaphalioides of Jacquin, with silvered leaves, which we found here for the first time. This is a social plant and is a shrub from four feet and a half to five feet high. Its flowers emit an agreeable perfume; and it is the ornament of Cayo Flamenco, Cayo Piedras and perhaps of the greater part of the low lands of the Jardinillos.
