An alligator, about fifteen feet long, swam about the vessel for some time, which made us afterwards rather cautious of walking through the high grass; but excepting a dog that followed the natives, no quadrupeds were seen.
Off the north point of the bay, at the distance of a furlong, and separated from it by a channel of from twelve to fifteen feet deep, are two rocks of the same formation as those on Sims' Island; on the largest was deposited a bottle containing a record on parchment of our visit.

On this rock all our observations were taken, excepting a few at the south end of the sandy beach, before the natives showed themselves: the longitude of Bottle Rock was subsequently determined to be 133 degrees 19 minutes 40 seconds.* (*Footnote.

Vide Appendix A Section X.) April 6.
We left South-west Bay on the 4th, and the following morning anchored in a bay on the west side of North Island, and on the 6th we commenced cutting our wood from a group of casuarinas that grew close to the beach.
In the afternoon, when our party returned on board to dinner, some natives were perceived examining our wooding-place, but our late experience had taught us the precaution of bringing our tools away, to prevent any further occasion of quarrel.

They did not stop long but walked on, as if they had some other object; at about forty yards farther they halted again, and concealing themselves as they thought behind a bank, they watched us for half an hour; after which they walked away and disappeared among the trees.
April 7.
On our revisiting the shore, we traced their steps through the grass, and came up with a shallow well containing fresh water, which they had evidently taken the opportunity of our absence to drink at.

Upon further search we found their encampment; it consisted of three or four dwellings of a very different description from any that we had before, or have since seen: they were of a conical shape, not more than three feet high, and not larger than would conveniently contain one person; they were built of sticks, stuck in the ground, and being united at the top, supported a roof of bark, which was again covered with sand, so that the hut looked more like a sand-hillock than the abode of a human creature: the opening was at one side, and about eighteen inches in diameter; but even this could be reduced when they were inside, by heaping the sand up before it.
