We did not leave our anchorage off Booby Island until the next morning, in order that we might obtain sights for the watches, and have the advantage of daylight for passing over the position assigned to a shoal, said to have been seen by the ship Aurora. After weighing we steered West-South-West for sixty miles without seeing any signs of it; and on this course our soundings very gradually increased to thirty fathoms. August 18 to 19. On our passage across the Gulf of Carpentaria we had very fine weather but the horizon was enveloped in haze. The South-East monsoon was steady but very light; and the wind during the day veered occasionally to North-East, which might here be called a sea-breeze. August 19. On the 19th we passed Cape Wessel. Hence we steered for Goulburn Islands. August 21. And on the afternoon of the 21st anchored in South West Bay, off the watering-place, which was running very slowly; a hole was dug to receive the drainings. August 22. And the next morning we commenced operations, but, from the small supply of water, our progress was very slow. The natives had not made their appearance, but knowing whom we had to deal with, every precaution was taken to prevent surprise: an armed party was stationed to protect the remainder of our people who were cutting down the trees which grew immediately over the watering-place on the brink of the cliff; and the officers and men were severally cautioned against straying away from the shore party without taking the precaution of carrying arms. Mr. Hunter and Mr. Cunningham ranged about the island near our wooding party; the former gentleman shot for us several birds, among which was a white cockatoo that differed from the species that is common at Port Jackson in being smaller and having a very small white crest or top-knot without any yellow feathers in it: its mandibles and feet were white but the feathers on the under part of the wings had the usual yellow tinge. Mr. Cunningham was successfully employed in adding to his collections, but the dry season was so far advanced and the country so parched up that everything bespoke the last season as having been unusually dry. August 23.
