Of the Grenadines, which form a curved chain between St. Vincent and Grenada, and which from their picturesque forms and distribution tend to make the voyage from one island to the other—a distance of about sixty miles, peculiarly agreeable, reminding one of the Cyclades of the Grecian Archipelago,—I shall notice only a few particulars.

They are said to be three hundred in number. Most of them however are mere rocks. The most considerable of the islets, those which are inhabited and cultivated, are Bequia, Mustique, Union, Canouan, dependencies of St. Vincent; Carriacou, Petit Martinique and Isle de Rhonde, dependencies of Grenada. Of the former, Bequia is the largest, comprising 3,700 acres; of the latter, Carriacou, which is about twice the size of Bequia, having an extent of 7,881 acres; the smallest of the others, Isle de Rhonde, is estimated at only 600 acres. Their relative situation and position is shown in the map prefixed. Their geological structure is but little known. From the specimens which I have obtained from Carriacou, for which, and a good deal of general information respecting that island, I am indebted to George Mitchell, Esq., of Carriacou, it would appear to be formed in part of igneous rocks, resembling those of St. Vincent, and in part of marl and of shell and coralline limestone, having a close resemblance to those similarly designated in Barbados.
