Those narrow straits of Sunda divide Sumatra from Java; and standing midway in that vast rampart of islands, buttressed by that bold green promontory, known to seamen as Java Head; they not a little correspond to the central gateway opening into some vast walled empire: and considering the inexhaustible wealth of spices, and silks, and jewels, and gold, and ivory, with which the thousand islands of that oriental sea are enriched, it seems a significant provision of nature, that such treasures, by the very formation of the land, should at least bear the appearance, however ineffectual, of being guarded from the all-grasping western world.
