After leaving Corea, we stood to the southward and eastward, with a strong breeze from the north, and a mountainous swell from the north-east. Shortly after daybreak on the 13th of September, we saw Sulphur Island, in the south-west quarter, and by eleven in the forenoon were close up to it. We intended to land, but were prevented by the high wind, which caused so great a surf all round the island, as to render this impracticable. The sulphuric volcano from which the island takes its name is on the north-west side; it emits white smoke, and the smell of sulphur is very strong on the lee side of the crater. The cliffs near the volcano are of a pale yellow colour, interspersed with brown streaks: the ground at this place is very rugged, as the strata lie in all directions, and are much broken; on the top is a thin coat of brown grass. The south end of the island is of considerable height, of a deep blood red colour, with here and there a spot of bright green: the strata, which are here nearly horizontal, are cut by a whin dyke running from the top to the bottom of the cliff, projecting from its face like a wall. As the weather still looked threatening, we gave up the intention of examining this spot, and proceeded to the southward till four o'clock, at which time land was seen in the south-west quarter; but as there was not sufficient daylight to close with it, we hauled off to the westward for the night. Shortly after sunset the sky became overcast, the wind veered about from one point to another, the air became suddenly quite chill, the sea rose high, and every thing, in short, seemed to indicate an approaching tyfoong or hurricane. All our preparations were made to encounter a violent tempest; but we were much pleased at finding it turn out nothing more than an ordinary gale of wind.
