By the north-east there is no way; the South-East Passage the Portuguese do hold, as the lords of those seas.

At the south-west, Magellan's experience hath partly taught us, and partly we are persuaded by reason, how the eastern current striketh so furiously on that strait, and falleth with such force into that narrow gulf, that hardly any ship can return that way into our west ocean out of Mare del Sur.

The which, if it be true, as truly it is, then we may say that the aforesaid eastern current, or Levant course of waters, continually following after the heavenly motions, loseth not altogether its force, but is doubled rather by another current from out the north-east, in the passage between America and the North Land, whither it is of necessity carried, having none other way to maintain itself in circular motion, and consequently the force and fury thereof to be no less in the Strait of Anian, where it striketh south into Mare del Sur beyond America (if any such strait of sea there be), than in the strait of Magellan, both straits being of like breadth, as in Belognine Salterius' table of "New France," and in Don Diego Hermano de Toledo's card for navigation in that region, we do find precisely set down.
Nevertheless, to approve that there lieth a way to Cathay at the north-west from out of Europe, we have experience, namely of three brethren that went that journey, as Gemma Frisius recordeth, and left a name unto that strait, whereby now it is called Fretum Trium Fratrum.

We do read again of a Portuguese that passed this strait, of whom Master Frobisher speaketh, that was imprisoned therefore many years in Lisbon, to verify the old Spanish proverb, "I suffer for doing well." Likewise, An.

Urdaneta, a friar of Mexico, came out of Mare del Sur this way into Germany; his card, for he was a great discoverer, made by his own experience and travel in that voyage, hath been seen by gentlemen of good credit.
Now if the observation and remembrance of things breedeth experience, and of experience proceedeth art, and the certain knowledge we have in all faculties, as the best philosophers that ever were do affirm truly the voyage of these aforesaid travellers that have gone out of Europe into Mare del Sur, and returned thence at the north-west, do most evidently conclude that way to be navigable, and that passage free; so much the more we are so to think, for that the first principle and chief ground in all geography, as Ptolemy saith, is the history of travel, that is, reports made by travellers skilful in geography and astronomy, of all such things in their journey as to geography do belong.
