1802.
August.
Tuesday 10.
shoal, the brig was obliged to anchor. I then went on in my boat for the nearest of the two islands, passing over the banks and crossing the narrow, deep channels marked in the plan. The two islands are mostly very low, and the shores so muddy and covered with mangroves, that a landing on the northern and highest of them could be effected only at the west end; but a hillock there enabled me to take an useful set of bearings, including Mount Larcom, which is visible from all parts of this bay, as it is from Port Curtis.
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 tideWednes. 11. rose to six and a half only. 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
