of the chain of mountains which forms the Ladrones, for these eleven eastern islands are all placed in the same direction from north to south, occupying a space of more than 200 leagues in length, the broadest of which is not more than 7 or 8 leagues from east to west. But if these conjectures are thought too presumptuous, on account of the great intervals between the islands bordering on Cape Ava, Japan, and the Callanos, and between these islands and the Ladrones, and between the Ladrones and the new Philippines, the first of which is in fact about 160 leagues, the second 50 or 60, and the third near 120, I shall answer that the chains of mountains often extend much farther under the waters of the sea, and that these intervals are small in comparison of the extent of land which these mountains in the above direction present, which is 1100 leagues, computing them from the interior part of Kamtschatka. In short, if we wholly reject this idea, as to the quantity of land the ocean must have gained on the eastern coasts of the continent, and on that suit of mountains, still it must be allowed that Kamtschatka, Jesso, Japan, the islands Bonga, Tanaxima, those of Great Lequeo, King's Island, Formosa, Vaif, Basha, Babuyane, Lucca, Mindano, Gilolo, &c. and lastly, Guinea, which extends to New Britain, and is situate under the same meridian as Kamtschatka, do not form a continuation of land of more than 2200 leagues, interrupted only by small intervals, the greatest of which perhaps is not more than 20 leagues, so that the ocean has formed in the lands of the eastern continent a great bay, which commences at Kamtschatka and ends at New Britain. This bay is interspersed with many islands, and has every appearance of having been gained from the land, consequently we may suppose, with some probability, that the ocean, by its constant motion from east to west, has by degrees acquired this extent on the eastern continent, and has formed mediterraneans, such as Kamtschatka, Corea, China, and perhaps all the Archipelago; for the earth and sea are there so blended that it evidently appears to be an inundated country, of which we only see the eminences and high lands, while the lower are hid under the waters of the ocean. This supposition appears to be in some measure confirmed by the water being more shallow than in other seas, and the innumerable islands resembling the tops of mountains.
