11th of October.--In the morning we again stood in, using the precaution of sending a boat a-head to sound the way; when we had nearly reached the entrance we anchored, and proceeded in three boats to examine the harbour discovered last night. As it was near noon when we passed the small island, we landed and observed the meridian altitude of the sun; after which we entered the harbour in the main island, by an intricate passage of about a quarter of a mile in length, and at one place not two hundred yards wide. Here we found ourselves in a circular bason upwards of half a mile across, with deep water, and completely sheltered from all winds. On its western shore we saw a large and beautiful village almost hid amongst trees, with a high wooded range behind it stretching to the south. The eastern shore was low and laid out in salt fields, with a few huts here and there. At first sight this bason did not appear to have any outlet except by the one we had examined; but on rowing to its upper or southern side, we found that it joined by a narrow channel with another harbour still larger, and if possible more beautiful than the first, for here the land was high on both sides, and richly wooded from top to bottom. Proceeding onwards through this bason, which had all the appearance of an inland lake, we came to another outlet, not above a hundred yards wide, formed by cliffs rising abruptly out of the water to the height of a hundred feet. Both sides being covered with trees, which almost met overhead, the space below was rendered cool and pleasant, and the water, thus sheltered from every wind, was as smooth as glass. We rowed along for some time by various windings through this fairy scene in total uncertainty of what was to come next, and at last, after advancing about three miles, it opened into an extensive lake several miles in length, studded with numerous small islands. The depth of water in the lake varied from four to six fathoms; but in the narrow neck which connects it with the sea the depth is from ten to twenty fathoms, being deepest at the narrowest parts. Ships might ride in any part of this extraordinary harbour, in perfect safety during the most violent tempests: and the shores are so varied, that every purpose of re-equipment might be served. At some places natural wharfs are formed by the rocks, and eight and ten fathoms water close to them. Ships might lie alongside these places, or might heave down by them: there are also shallow spots on which ships might be careened. Many of the cliffs are hollowed into caves, which would answer for storehouses; and in the numerous lawns on both sides encampments might be formed of any number of people.
