This island is entirely composed of volcanic matter, in some places alternating with submarine productions. The principal mountain is situated at the western end of the island; it is an exhausted volcano, called in books of navigation, charts, &c., Mount Misery. The summit of this mountain is 3,711 feet above the sea; it appears to consist of large masses of volcanic rocks, roasted stones, cinders, pumice, and iron-clay. The whole extent of land, to the sea-shore on either side, may be considered as the base of this mountain, as it rises with a pretty steep ascent towards it; but from the part which is generally considered the foot of the mountain, it takes a sudden rise of an average angle of about 50 degrees. To the east, another chain of mountains runs, of a similar formation, though of inferior height. On the summits of these there are no remains that indicate their having ever possessed a crater: so that whether any of them have originally been volcanoes, or whether they have been formed by an accumulation of matter thrown out of Mount Misery, it is difficult to decide. That the low lands have been thrown from the mouth of the volcano is evident, from the regular strata of volcanic substances of which they consist; these too are interspersed with masses of volcanic rock, and other stones, some of the lesser ones entirely roasted through, and some of the larger ones to certain depths from their surfaces. Masses, also, of iron-clay, enclosing various pebbles, which have been burnt into a kind of red brick, are abundantly found in many places. There is scarcely any thing that can be called a path, or even a track, to the mouth of the crater of Mount Misery; indeed, there are but few whose curiosity is sufficiently strong to induce them to undertake this expedition. The common course for those who do, is to take a negro man as a guide, with a cutlass, or large knife, to clear away the underwood, and form a kind of path as he goes on. The ascent is very irregular, in some places being gentle, in others almost perpendicular; in which case the hands are obliged to assist the operations of the feet. In wet weather, the ascent of this mountain is extremely laborious, as a great part of it consists of clay, which then becomes so slippery as to render the getting up almost impracticable. About half-way up on the south side, and in a very pretty, romantic situation, there is a natural spring of remarkably cool water. On the north side, at about the same height, there is a waterfall, which, though small and insignificant in itself, has a pleasing appearance, as it rushes over the rocks, and through the trees and shrubs. This mountain is thickly clothed with wood, which in many places not only excludes the rays of the sun, but produces a sombre, gloomy appearance; this, with the occasional plaintive coo of the mountain dove, (the only sound heard at this height,) creates in the mind sensations of pleasing melancholy.
