This was the only voyage which I may say was successful in all my adventures, which I owe to the integrity and honesty of my friend the captain; under whom also I got a competent knowledge of the mathematics and the rules of navigation, learned how to keep an account of the ship’s course, take an observation, and, in short, to understand some things that were needful to be understood by a sailor; for, as he took delight to instruct me, I took delight to learn; and, in a word, this voyage made me both a sailor and a merchant; for I brought home five pounds nine ounces of gold-dust for my adventure, which yielded me in London, at my return, almost £300; and this filled me with those aspiring thoughts which have since so completed my ruin.
Esto se lo debo a la integridad y honestidad de mi amigo el capitán, de quien también obtuve un conocimiento digno de las matemáticas y de las reglas de navegación, aprendí a llevar una bitácora de viaje y a fijar la posición del barco. En pocas palabras, me transmitió conocimientos imprescindibles para un marinero, que él se deleitaba enseñándome y yo, aprendiendo.
