melodies I thought them, but Kate said they were very pretty, and expressed a wish to learn the guitar. Directly one of the officers undertook to instruct her, and presented her with a handsome instrument, which he said he hoped she would keep in remembrance of her visit to the _Andorinha_. The time thus passed very pleasantly on board. Still having some doubts from what Timbo had said about the vessel, I asked Jack, whom I met the next morning, what he thought of her. "Well, sir," he answered, "the people seem a free-and-easy set, rather fond of gambling--but that's the way with these foreigners; and most of them wear long ugly knives stuck in their belts, which is not the fashion with English seamen; but these Portuguese are odd fellows, and that is how I accounts for it." With Timbo I had no opportunity for some time of speaking. Next morning I saw that the Portuguese flag was flying from the schooner's peak, while a pennant waved from her mast-head. Certainly the officers did their best to amuse their fair guests and us. Next day, after dinner, some of the men were called aft to dance their national dances, but I can't say much for them. I saw that one or two of the men were always aloft on the look-out, and while the crew were engaged as I have before described, one of the look-outs gave a shout from aloft, and presently two of the officers went up the rigging with glasses at their backs. I saw them looking eagerly to the southward. Presently they returned on deck and reported their observations to the captain. The breeze, which had before been fresh, had by degrees been falling, and now failing us altogether, the schooner lay becalmed with her sails flapping against the masts. From this I concluded that a sail had been sighted--a slaver possibly. The officers continued talking together, while one of them, who had gone aloft, remained there, his eye constantly fixed in the direction in which I supposed he had seen the stranger. I was about to go aloft with my spy-glass, when Senhor Silva came on deck. "The captain says that passengers going up the rigging will interfere with the duty of the ship," he observed; "you must remain on deck." I thought this was very odd, but of course obeyed. The schooner lay without moving on the calm ocean. Some time passed. The officers continued pacing the deck, looking even more anxious, I fancied, than before. At length, as I swept the horizon with my telescope, I observed a white sail rising above it. I looked again, and made out the royals and part of the topgallant-sails of a square-rigged vessel. I shut up my glass quickly, however, as I saw the captain looking somewhat angrily towards me. "You had better go below," said Senhor Silva, coming up to me. "Ask no questions, and do not say what you have seen. It will be better for you to do as I advise, and before long I will explain matters to you."
