by the flatness of their lee side, and their small breadth, they are capable of lying much nearer the wind than any other vessel hitherto known, and thereby have an advantage which no vessels that go large can ever pretend to. The advantage I mean is that of running with a velocity nearly as great, and perhaps sometimes greater, than what the wind blows with. This, however paradoxical it may appear, is evident enough in similar instances on shore, since it is well known that the sails of a windmill often move faster than the wind; and one great superiority of common windmills over all others that ever were, or ever will be, contrived {314} to move with an horizontal motion, is analogous to the case we have mentioned of a vessel upon a wind and before the wind: for the sails of an horizontal windmill, the faster they move the more they detract from the impulse of the wind upon them; whereas the common windmills, by moving perpendicular to the torrent of air, are nearly as forcibly acted on by the wind when they are in motion as when they are at rest. Thus much may suffice as to the description and nature of these singular embarkations. I must add that vessels bearing some obscure resemblance to these are to be met with in various parts of the East Indies, but none of them, that I can learn, to be compared with those of the Ladrones, either for their construction or celerity; which should induce one to believe that this was originally the invention of some genius of these islands, and was afterwards imperfectly copied by the neighbouring nations: for though the Ladrones have no immediate intercourse with any other people, yet there lie to the S. and S.W. of them a great number of islands, which are imagined to extend to the coast of New Guinea. These islands are so near the Ladrones that canoes from them have sometimes by distress been driven to Guam, and the Spaniards did once dispatch a bark for their discovery, which left two Jesuits amongst them, who were afterwards murthered. Whence it may be presumed that the inhabitants of the Ladrones, with their proas, may by storms or casualties have been driven amongst those islands. Indeed, I should conceive that the same range of islands stretches to the S.E. as well as the S.W., and to a prodigious distance, for Schouten, who traversed the south part of the Pacific Ocean in the year 1615, met with a large double canoe full of people above a thousand leagues from the Ladrones, towards the S.E. If that double canoe was any distant imitation of the flying proa, which is no very improbable conjecture, it must then be supposed that a range of islands, near enough to each other to be capable of an accidental communication, is continued thither from the Ladrones. This seems to be farther evinced from hence, that all those who have crossed from America to the East Indies in a southern latitude have never failed of discovering several very small islands scattered over that immense ocean.
