THE NAUTICAL MAGAZINE AND Nabal Chronicle. JANUARY 1850. Description of the Island of CoRVO.-By Capt.A. T.E. Vidal, R.N. THE Island of Corvo is the northernmost of the Azores, and is formed by a single volcanic mountain. Its extent from north to south is three miles and a half, from east to west two miles and a quarter, and in circuit it exceeds nine miles and a half. The crater of the volcano, which has not been in action since the discovery of the island, occupies all the north-western portion of it, and is called the Caldeira. It is a deep oval basin, and has the edge or rim of it formed by a narrow ridge of lava of very irregular outline, covered with deep soft spongy moss, long coarse grass and heather. It is about 7,500 feet across from north to south, 4,500 from east to west, and three miles and a quarter in circumference. The most elevated part of the Caldeira is on its south-west side, where it rises to the height of 2,548 feet. On the north some part of the ridge is about 2,200 feet high: the eastern and western margins are considerably lower, in some places not exceeding 1,434 feet. At the bottom of the basin, on its north side, there are two small lagoons separated from each other by a narrow neck of land, from which a rocky point crowned by a hill extends north-east into the eastern lagoon. The western one, which is the largest piece of water, has a very similar point projecting into it from the same narrow neck of land to the westward, and is embellished by three small islets tufted with shrubs. The surface of this lagoon, which is a few feet below the level of the eastern one, is 1,273 feet above the sea, and 1,275 below the NO. 1.-VOL. XIX. B |
