But they could not bolt east until they were sure of the right latitude, and so every day they posted lookouts at the top of Minerva ’s foremast and had them scan the horizon for the sails of the Manila Galleon. Having sighted her, they would plot a converging course, and creep closer until they could see how her sails had been trimmed. The winds almost always came from the southeastern quarter of the compass rose, and every time they caught sight of the Galleon she seemed to be going free, which was a way of saying that the wind was coming in from behind her and from one side—in this case, the starboard. In other words the Galleon’s captain was still bending all his efforts to gain latitude, and seemed not to know or care that he had five thousand miles to cover eastwards; or that every degree he went north was a degree he’d later have to go south (Manila and Acapulco lying at nearly the same latitude).
