178 accurately, his group of islands. On one side of this bay appeared a large piece of level land, or a plain, which Mark supposed might cover one or two thousand acres. Its colour was so different from anything he had yet seen, that our young man was induced to land, and to walk a short distance to examine it. On reaching its margin, it was found to be a very shallow basin, of which the bottom was mud, with a foot or two of salt water still remaining, and in which sea-weed, some ten or twelve inches in thickness, was floating. It was almost possible for Mark to walk on this weed, the green appearance of which induced him to name the place the Prairie. Such a collection of weed could only have been owing to the currents, which must have brought it into this basin, where it was probably retained even previously to the late eruption. The presence of the deposit of mud, as well as the height of the surrounding rocks, many of which were doubtless out of water previously to the phenomenon, went to corroborate this opinion.

After working her way through a great many channels, some wide and some narrow, some true and some false, the Bridget reached the southern verge of the group, about noon. Mark then supposed himself to be quite twenty miles from the Reef, and the Peak appeared very little nearer than when he left it. This startled him on the score of distance; and, after meditating on all his chances, the young man determined to pass the remainder of that day where he was, in order to put to sea with as much daylight before him as possible. He desired also to explore the coast and islands in that vicinity, in order to complete his survey of the cluster. He looked for a convenient place to anchor his boat, accordingly, ate his dinner, and set out on foot to explore, armed as usual with a fowling-piece.

In the first place, an outlet to the sea very different from that on the eastern side of the group, was found here, on its southern. The channel opened into a bay of some size, with an arm of rock reaching well off on the weather side, so that no broken water was encountered in passing into or out of it, provided one kept sufficiently clear of the point itself. As there was abundance of room, Mark saw
