Nothing is more certain of the Portuguese than this, take them nationally or personally, if they are animated and heartened up by anybody to go before, and encourage them by example, they will behave well enough; but if they have nothing but their own measures to follow, they sink immediately: these men had certainly fled from a parcel of naked savages, though even by flying they could not have saved their lives, if I had not shouted and hallooed, and rather made sport with the thing than a fight, to keep up their courage. Nor was there less need of it upon several occasions hereafter; and I do confess I have often wondered how a number of men, who, when they came to the extremity, were so ill supported by their own spirits, had at first courage to propose and to undertake the most desperate and impracticable attempt that ever men went about in the world. There were indeed two or three indefatigable men among them, by whose courage and industry all the rest were upheld; and indeed those two or three were the managers of them from the beginning; that was the gunner, and that cutler whom I call the artist; and the third, who was pretty well, though not like either of them, was one of the carpenters. These indeed were the life and soul of all the rest, and it was to their courage that all the rest owed the resolution they showed upon any occasion. But when those saw me take a little upon me, as above, they embraced me, and treated me with particular affection ever after. This gunner was an excellent mathematician, a good scholar, and a complete sailor; and it was in conversing intimately with him that I learned afterwards the grounds of what knowledge I have since had in all the sciences useful for navigation, and particularly in the geographical part of knowledge. Even in our conversation, finding me eager to understand and learn, he laid the foundation of a general knowledge of things in my mind, gave me just ideas of the form of the earth and of the sea, the situation of countries, the course of rivers, the doctrine of the spheres, the motion of the stars; and, in a word, taught me a kind of system of astronomy, which I afterwards improved.
