A sea breeze had sprung up from the eastward, and the ship was under way when we returned on board at three in the afternoon. At five we hauled round Chasm Island with 12 fathoms water, which diminished gradually as we proceeded up the bay, to 4½, where the anchor was dropped on a muddy bottom; the south-west end of Chasm Island then bore N. 16° E., three or four miles, and the cliffy end of a smaller isle on the west side of the entrance, N. 29° W. two miles and a half; and except between these two bearings, we were sheltered from all winds. The situation of this bay in Groote Eylandt, led me to give it the name of _North-west Bay_. It is formed on the east and south by that island; and on the west by a separate piece of land, five or six miles long, which, in honour of the noble possessor of Burley Park, in the county of Rutland, I named _Winchilsea Island_; and a small isle of greater elevation, lying a short mile to the east of the ship, was called _Finch's Island_. SATURDAY 15 JANUARY 1803 Early next morning the botanists landed on Groote Eylandt, and I went to Finch's Island with the second lieutenant, to take bearings and astronomical observations. From the western head, I saw that the bay extended six or eight miles above the ship, to the southward, and that the southern outlet, beyond Winchilsea Island, was about one mile wide; but the whole seemed to be too shallow for any thing larger than boats. Amongst the bearings taken from this station, those most essential to the survey were, Groote Eylandt, the woody north-west bluff, S. 56° 46' W. A distant wedge-shaped rock, the N. E. bluff, N. 59 55 W. Chasm I., the steep west end, N. 3 51 E. And from another station, half a mile to the E. S. E., I set Groote Eylandt, the central hill, at S. 14° 27' E. This bearing and that of the north-west bluff, formed connecting links in the chain of longitude round the island. SUNDAY 16 JANUARY 1803 Next day the botanists landed upon Winchilsea Island, and further astronomical observations were taken upon that of Finch; where also a part of the ship's company went to divert themselves, and to wash their linen; and in the evening, we prepared to quit North-west Bay.
