Furthermore, it were to small purpose to make so long, so painful, so doubtful a voyage by such a new found way, if in Cathay you should neither be suffered to land for silks and silver, nor able to fetch the Molucca spices and pearl for piracy in those seas. Of a law denying all aliens to enter into China, and forbidding all the inhabiters under a great penalty to let in any stranger into those countries, shall you read in the report of Galeotto Petera, there imprisoned with other Portuguese, as also in the Japanese letters, how for that cause the worthy traveller Xavierus bargained with a barbarian merchant for a great sum of pepper to be brought into Canton, a port in Cathay. The great and dangerous piracy used in those seas no man can be ignorant of that listeth to read the Japanese and Indian history. Finally, all this great labour would be lost, all these charges spent in vain, if in the end our travellers might not be able to return again, and bring safely home into their own native country that wealth and riches they in foreign regions with adventure of goods and danger of their lives have sought for. 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.
