Sunday, October 5th. It was our morning watch; when, soon after the day began to break, a man on the forecastle called out, ``Land ho!'' I had never heard the cry before, and did not know what it meant (and few would suspect what the words were, when hearing the strange sound for the first time); but I soon found, by the direction of all eyes, that there was land stretching along on our weather beam. We immediately took in studding-sails and hauled our wind, running in for the land. This was done to determine our longitude; for by the captain's chronometer we were in 25° W., but by his observations we were much farther; and he had been for some time in doubt whether it was his chronometer or his sextant which was out of order. This land-fall settled the matter, and the former instrument was condemned, and, becoming still worse, was never afterwards used. As we ran in towards the coast, we found that we were directly off the port of Pernambuco, and could see with the telescope the roofs of the houses, and one large church, and the town of Olinda. We ran along by the mouth of the harbor, and saw a full-rigged brig going in. At two P.M. we again stood out to sea, leaving the land on our quarter, and at sundown it was out of sight. It was here that I first saw one of those singular things called catamarans. They are composed of logs lashed together upon the water, the men sitting with their feet in the water; have one large sail, are quite fast, and, strange as it may seem, are trusted as good sea boats. We saw several, with from one to three men in each, boldly putting out to sea, after it had become almost dark. The Indians go out in them after fish, and as the weather is regular in certain seasons, they have no fear. After taking a new departure from Olinda, we kept off on our way to Cape Horn.
