While we lay at Guam we took up a resolution of going to Mindanao, one of the Philippine Islands, being told by the friar and others that it was exceedingly well stored with provisions; that the natives were Mohammedans, and that they had formerly a commerce with the Spaniards, but that now they were at wars with them. This island was therefore thought to be a convenient place for us to go; for besides that it was in our way to the East Indies, which we had resolved to visit; and that the westerly monsoon was at hand, which would oblige us to shelter somewhere in a short time, and that we could not expect good harbours in a better place than in so large an island as Mindanao: besides all this, I say, the inhabitants of Mindanao being then, as we were told (though falsely) at wars with the Spaniards, our men, who it should seem were very squeamish of plundering without licence, derived hopes from thence of getting a commission there from the prince of the island to plunder the Spanish ships about Manila, and so to make Mindanao their common rendezvous. And if Captain Swan was minded to go to an English port yet his men, who thought he intended to leave them, hoped to get vessels and pilots at Mindanao fit for their turn, to cruise on the coast of Manila. As for Captain Swan he was willing enough to go thither as best suiting his own design; and therefore this voyage was concluded on by general consent.
Accordingly June 2nd 1686 we left Guam bound for Mindanao. We had fair weather and a pretty smart gale of wind at east for 3 or 4 days, and then it shifted to the south-west being rainy, but it soon came about again to the east and blew a gentle gale; yet it often shuffled about to the south-east. For though in the East Indies the winds shift in April, yet we found this to be the shifting season for the winds here; the other shifting season being in October, sooner or later, all over India. As to our course from Guam to the Philippine Islands, we found it (as I intimated before) agreeable enough with the account of our common charts.
