On viewing one of these isolated masses, at first one is inclined to believe that it has been suddenly pushed up in a semi-fluid state.

At St.
Helena, however, I ascertained that some pinnacles, of a nearly similar figure and constitution, had been formed by the injection of melted rock into yielding strata, which thus had formed the moulds for these gigantic obelisks.

The whole island is covered with wood; but from the dryness of the climate there is no appearance of luxuriance.

Half-way up the mountain some great masses of the columnar rock, shaded by laurel-like trees, and ornamented by others covered with fine pink flowers but without a single leaf, gave a pleasing effect to the nearer parts of the scenery.
BAHIA, OR SAN SALVADOR.

The day has past delightfully.
