Its mean height hardly equals 750 toises or 4 795 English feet; yet single summits, like the Silla de Caracas (also called Cerro de Avila), decked with the purpleflowering Befaria, the American Rose of the Alps, rise 1350 toises, or 8630 English feet, above the level of the sea. The coast of Terra Firma bears traces of devastation. We recognize everywhere the action of the great current which, sweeping from east to west, formed by disruption the West Indian Islands, and hollowed out the Caribbean gulf. The projecting tongues of land of Araja and Chuparipari, and especially the coast of Cumana and New Barcelona, offer a remarkable spectacle to the geologist. The precipitous Islands of Boracha, Caracas, and Chimanas rise like towers from the sea, and bear witness to the terrible pressure of the waters against the mountain chain when it was broken by their irruption. Perhaps, like the Mediterranean, the Antillean gulf was once an inland sea, which became suddenly connected with the ocean. The islands of Cuba, Hayti, and Jamaica still contain the remnants of the lofty mountains of mica slate which bo~nded this sea to the north. It is remarkable that where these three islands approach each other most nearly, the highest summits are found; and we may conjecture that the highest part of this Antillean chain was situated between Cape Tiburon and Point Morant. The Copper Mountains (Montafias de Cobre) near Santiago de Cuba, have not yet been measured, but their elevation is probably greater than that of the Blue Mountains of Jamaica, (1138 toises, 7277 English feet,) which somewhat exceeds the height of the St. Gothard Pass. My conjectures on the valley-form of the Atlantic Ocean, and on the ancient connection of the continents, were given more in detail in a memoir written in Cumana, entitled Fragment d'un Tableau Geologique de I' Amerique Meridionale (Journal de Physique, Messidor, An. IX.). It is worthy of remark that Columbus himself, in his Official Reports, called attention to the connection between the direction of the equatorial current and the form of the coast line of the larger Antilles.
