They traversed the thirtieth parallel, which meant that they had reached the latitude of southern Japan. Still they continued north. They could not keep the Galleon in sight all the time, of course. But it was not necessary to follow in her wake. They had only two requirements. One was to discover the magic latitude, known only to the Spanish, that would take them safely to California. The other was to arrive in Acapulco at about the same time as the Galleon, so that certain officers aboard that ship could smooth the way for them. With her narrow hull Minerva could not carry as many provisions as the Galleon, but she could sail faster, and so the general plan was to speed across the Pacific and then tarry off California for a few weeks, surviving on the fresh water and game of that country, while keeping a lookout for the Galleon.
