The next day, about three P. M., passed a large corvette-built ship, close upon the wind, with royals and skysails set fore and aft, under English colors. She was standing south-by-east, probably bound round Cape Horn. She had men in her tops, and black mast-heads; heavily sparred, with sails cut to a t, and other marks of a man-of-war. She sailed well, and presented a fine appearance; the proud, aristocratic-looking banner of St. George, the cross in a blood-red field, waving from the mizen. We probably were as fine a sight, with our studding-sails spread far out beyond the ship on either side, and rising in a pyramid to royal studding-sails and sky-sails, burying the hull in canvas, and looking like what the whale-men on the Banks, under their stump top-gallant masts, call "a Cape Horn-er under a cloud of sail." Friday, August 12th. At daylight made the island of Trinidad, situated in lat. 20° 28' S., long. 29° 08' W. At twelve M., it bore N. W. 1/2 N., distant twenty-seven miles. It was a beautiful day, the sea hardly ruffled by the light trades, and the island looking like a small blue mound rising from a field of glass. Such a fair and peaceful-looking spot is said to have been, for a long time, the resort of a band of pirates, who ravaged the tropical seas. Thursday, August 18th. At three P. M., made the island of Fernando Naronha, lying in lat. 3° 55' S., long. 32° 35' W.; and between twelve o'clock Friday night and one o'clock Saturday morning, crossed the equator, for the fourth time since leaving Boston, in long. 35° W.; having been twenty-seven days from Staten Land--a distance, by the courses we had made, of more than four thousand miles. We were now to the northward of the line, and every day added to our latitude. The Magellan Clouds, the last sign of South latitude, were sunk in the horizon, and the north star, the Great Bear, and the familiar signs of northern latitudes, were rising in the heavens.
