We were on our way to Point Hall before the eastern hills had received their golden hue from the rays of the rising sun, and landed to ascend the summit of that headland from the bay, on its South-East side, which proved to be a safe anchorage, except with South-West winds, having a small islet in its centre. We ascended the height on the lee side, and as the sun was now approaching the zenith the heat became very oppressive; but the air was quite perfumed with the rich fragrance of different gums. This warm aromatic odour we always experienced in a slighter degree on first landing in North-western Australia. REMARKABLE TREE. I noticed a tree quite new to me, it was of stunted growth, bearing a fruit resembling a small russet apple, which hung in clusters at the extremity of small branches; the skin was rough, covering a pulp that had an acid flavour, inside of which was a large stone, and I observed a white fluid exuded from the branches when broken. Although this was almost a solitary tree, I have since learnt it grows in the southern parts of the continent. As the woodcut and description given in page 82, Volume 1 of Sir Thomas Mitchell's work on Australia, is almost identical with this fruit, it must be indigenous to a great extent of country, since Sir Thomas Mitchell found it in latitude 29 degrees 50 minutes South whilst by us it was discovered in 15 degrees 40 minutes South. We did not observe any other change in the vegetation on this point; of birds we saw but few, chiefly parrots, some of which we shot. A coast range of brown grassy hills prevented our seeing anything of the interior. To seaward there was neither islet nor reef to interrupt the blue surface of water that bounded our view in the far north-west. Descending we embarked from a cove on the North-East side, where the boats had been ordered to meet us; between this and one on the opposite side there was only a narrow neck of low land. It is singular that we should not have seen any natives, or even traces of them anywhere excepting at Raft Point, during the whole of this cruise. THE SLATE ISLES. Pursuing our northerly course, we reached a small group of islands, named from their formation, Slate Isles. Finding that all the material required here for the chart could not be collected this evening, I desired Mr. Helpman to go on to Brecknock harbour, to sound and examine its southern shore the next morning, whilst Mr. Fitzmaurice and myself remained to complete the survey hereabouts.
