In the afternoon of the 23d, as soon as the ship was moored, I went on shore to examine the watering-place, accompanied by Mr. Banks and Dr. Solander: the boat landed in the cove, without the least surf; the water was excellent, and conveniently situated; there was plenty of wood close to high-water mark, and the disposition of the people was in every respect such as we could wish. Having, with Mr. Green, taken several observations of the sun and moon, the mean result of them gave 180° 47ʹ W. longitude; but, as all the observations made before exceeded these, I have laid down the coast from the mean of the whole. At noon, I took the sun’s meridian altitude with an astronomical quadrant, which was set up at the watering-place, and found the latitude to be 38° 22ʹ 24ʺ. On the 24th, early in the morning, I sent Lieutenant Gore on shore, to superintend the cutting of wood and filling of water, with a sufficient number of men for both purposes, and all the marines as a guard. After breakfast, I went on shore myself, and continued there the whole day. Mr. Banks and Dr. Solander also went on shore to gather plants, and in their walks saw several things worthy of notice. They met with many houses in the valleys that seemed to be wholly deserted, the people living on the ridges of the hills in a kind of sheds very slightly built. As they were advancing in one of these valleys, the hills on each side of which were very steep, they were suddenly struck with the sight of a very extraordinary natural curiosity. It was a rock, perforated through its whole substance, so as to form a rude but stupendous arch or cavern, opening directly to the sea: this aperture was seventy-five feet long, twenty-seven broad, and five-and-forty high, commanding a view of the bay and the hills on the other side, which were seen through it, and, opening at once upon the view, produced an effect far superior to any of the contrivances of art.
