As the adoption of the name of Peru does not stand alone, we will treat of other similar names which were given before and after it: for though we shall thus anticipate a little, it will not be amiss to do so, that their origin may be known when we come to them in their places. And the first shall be Puerto Viejo, because it is near the place where the name of Peru originated. It must be known then that the sea from Panama to the city of the kings is navigated with much difficulty, owing to the currents and the southerly winds, which are always met with on that coast. By reason of these foul winds ships were obliged to sail out of a port on one tack for twenty or thirty leagues, and to return to the coast on the other, and in this manner they navigated the coast, always sailing on a bowline. It often happens that when a vessel does not sail well on a wind, she finds herself further to leeward than when she started from the coast. When Francis Drake, the Englishman, entered by the Straits of Magellan, he learnt a better way of navigating, by extending the length of the tacks for three or four hundred leagues out to sea.
