In the afternoon I proceeded up the western arm, having from 3 to 8 fathoms close along the northern shore; and about four miles up, where the width was diminished to one mile, found a landing place, a rare convenience here, and ascended a hill from whence there was a good view. At five or six leagues to the south, and extending thence north-westward, was a continuation of the same chain of hills which rises near Bustard Bay and passes behind Mount Larcom; but at the back of Keppel Bay it forms a more connected ridge, and is rocky, steep, and barren. Within this ridge the land is low, and intersected by various streams, some falling into the western arm at ten or twelve miles above the entrance, and others into the south-west and south arms of the bay. The borders of the western arm, and of its upper branches so far as could be perceived, were over-run with mangroves; whence it seemed probable the water was salt, and that no landing was practicable, higher than this station; the sun also was near setting when my bearings from _West-arm Hill_ were completed; and I therefore gave up the intention of proceeding further, and returned to the northern island in the entrance, to pass the night. It was high water here at seven in the evening, and the tide fell nine and a half feet; but the morning's tide rose to six and a half only [WEDNESDAY 11 AUGUST 1802]. In rowing out between the two islands, I had from 8 to 3 fathoms; but shoal water in crossing from thence to the entrance of the south-west arm, where again there was 5 to 8 fathoms. A strong wind from the south-eastward did not permit me to go up this arm, and the extensive flats made it impossible to land upon the south side of the bay; and finding that nothing more could be done at this time, I returned to the ship. The numerous shoals in Keppel Bay rendering the services of the Lady Nelson in a great measure useless to the examination, I directed lieutenant Murray to run out to the hummocky island lying to the north-east from Cape Keppel, and endeavour to take us some turtle; for there were no signs of inhabitants upon it, and turtle seemed to be plentiful in this neighbourhood. He was also to ascend the hills, and take bearings of any island or other object visible in the offing; and after making such remarks as circumstances might allow, to return not later than the third evening.
