Green, the captain, who came with me, was, from the time I saved his life, an altered man. He had been, as I was informed, a drunken profligate; but from the moment when I received him into my boat, his manners and habits seemed as completely changed as if he were a different being. He never drank more than was sufficient to quench his thirst--he never swore--he never used any offensive language. He read the Scriptures constantly, was regular in the morning and evening devotion, and on every occasion of quarrel or ill-will in the brig, which was perpetually occurring, Green was the umpire and the peacemaker. He saved the captain and chief mate a world of trouble; by this system, violent language became uncommon on board, punishment was very rare, and very mild. The men were happy, and did their duty with alacrity; and but for Peleg Oswald, all would have been harmony. We made the island about the 15th of December, when the weather was such as the season of the year might induce us to expect, it being then summer. We hove off to the north or windward side of the island, about two miles from the shore; we dared not go nearer on that side, for fear of what are called the "Rollers"--a phenomenon, it would appear, of terrific magnitude, on that sequestered little spot. On this extraordinary operation of nature, many conjectures should have been offered, but no good or satisfactory reason has ever been assigned to satisfy my mind; for the simple reason, that the same causes would produce the same effect on St. Helena, Ascension, or any other island or promontory exposed to a wide expanse of water. I shall attempt to describe the scene that a succession, of rollers would present, supposing, what has indeed happened, that a vessel is caught on the coast when coming in.
