chapter 19._
"The voyage [of Magellan] … was doubtless the greatest feat of navigation that has ever been performed, and nothing can be imagined that would surpass it except a journey to some other planet. It has not the unique historic position of the first voyage of Columbus, which brought together two streams of human life that had been disjoined since the Glacial Period. But as an achievement in ocean navigation that voyage of Columbus sinks into insignificance by the side of it, and when the earth was a second time encompassed by the greatest English sailor of his age, the advance in knowledge, as well as the different route chosen, had much reduced the difficulty of the performance. When we consider the frailness of the ships, the immeasurable extent of the unknown, the mutinies that were prevented or quelled, and the hardships that were endured, we can have no hesitation in speaking of Magellan as the prince of navigators."
