Sunday, August 30th. This was the first Sunday that the Alert's crew had been in San Diego, and of course they were all for going up to see the town. The Indians came down early, with horses to let for the day, and those of the crew who could obtain liberty went off to the Presidio and Mission, and did not return until night. I had seen enough of San Diego, and went on board and spent the day with some of the crew, whom I found quietly at work in the forecastle, either mending and washing their clothes, or reading and writing. They told me that the ship stopped at Callao on the passage out, and lay there three weeks. She had a passage of a little over eighty days from Boston to Callao, which is one of the shortest on record. There they left the Brandywine frigate, and some smaller American ships of war, and the English frigate Blonde, and a French seventy-four. From Callao they came directly to California, and had visited every port on the coast, including San Francisco. The forecastle in which they lived was large, tolerably well lighted by bull's-eyes, and, being kept perfectly clean, had quite a comfortable appearance; at least, it was far better than the little, black, dirty hole in which I had lived so many months on board the Pilgrim. By the regulations of the ship, the forecastle was cleaned out every morning; and the crew, being very neat, kept it clean by some regulations of their own, such as having a large spit-box always under the steps and between the bits, and obliging every man to hang up his wet clothes, &c. In addition to this, it was holystoned every Saturday morning. In the after part of the ship was a handsome cabin, a dining-room, and a trade-room, fitted out with shelves, and furnished with all sorts of goods. Between these and the forecastle was the ``between-decks,'' as high as the gun-deck of a frigate, being six feet and a half, under the beams. These between-decks were holystoned regularly, and kept in the most perfect order; the carpenter's bench and tools being in one part, the sailmaker's in another, and boatswain's locker, with the spare rigging, in a third. A part of the crew slept here, in hammocks swung fore and aft from the beams, and triced up every morning. The sides of the between-decks were clapboarded, the knees and stanchions of iron, and the latter made to unship. The crew said she was as tight as a drum, and a fine sea boat, her only fault being-- that of most fast ships-- that she was wet forward. When she was going, as she sometimes would, eight or nine knots on a wind, there would not be a dry spot forward of the gangway. The men told great stories of her sailing, and had entire confidence in her as a ``lucky ship.'' She was seven years old, had always been in the Canton trade, had never met with an accident of any consequence, nor made a passage that was not shorter than the average. The third mate, a young man about eighteen years of age, nephew of one of the owners, had been
