ies, and covering half of the difficulties which awaited us on our attempt to travel over it. The creek, in and along the bed of which we wound slowly down, was frequently covered with large loose boulders, between which our horses and cattle often slipped. A precipice, and perpendicular rocks on both sides, compelled us to leave it; and following one of its tributary creeks to its head, to the northward, we came to another, which led us down to a river running to the west by south. With the greatest difficulty we went down its steep slopes, and established our camp at a large water-hole in its bed. The longitude of the river was, according to my reckoning, 133 degrees 6 minutes.
A new species of rock pigeon (Petrophassa, Gould.) with a dark brown body, primaries light brown without any white, and with the tail feathers rather worn, lived in pairs and small flocks like Geophaps, and flew out of the shade of overhanging rocks, or from the moist wells which the natives had dug in the bed of the creek, around which they clustered like flies round a drop of syrup. A fine shady Eucalyptus, with a short barrel, but large spreading branches, and with the grey bark of the box, grew between the rocks along the creek.
Nov. 12. — We had been compelled to leave the injured horse behind, and upon going this morning with Charley to fetch it to the camp, we found the poor brute dead. On our return to the camp, we followed another creek to the northward, which also joined the river, about eight miles to the eastward of our camp. The river was densely covered with scrub, and almost perpendicular cliffs bounded its valley on both sides. Myriads of flying-foxes were here suspended in thick clusters on the highest trees in the most shady and rather moist parts of the valley. They started as we passed, and the flapping of their large membranous wings produced a sound like that of a hail-storm.
Nov. 13. — The two horses ridden by Charley and myself yesterday, had suffered so severely, that I had to allow them a day of rest to recover. In the mean time, I went with Charley and Brown to the spot where we had seen the greatest number of flying-foxes, and, whilst I was examining the neighbouring trees, my companions shot sixty-seven, of which fifty-five were brought to our camp; which served for dinner, breakfast, and luncheon, each individual receiving eight. The flying-fox lived here on a small, blue, oval stone-fruit, of an acid taste, with a bitter kernel; it grew on a tree of moderate size. Very small specimens of the Seaforthia palm were here observed for the first time; and the large scarlet fruit of Eugenia was found.
During the night, we heard the first grumbling of thunder since many months.
Nov. 14. — We travelled about twelve miles north by west. After crossing the river, we followed a rocky creek to its head, and passed over ten miles of level sandy country of stringy-bark forest, with Melalcuca gum and Banksia, interrupted only by a small Pandanus creek. At the end of the stage, we came to rocky creeks, one of which headed in a drooping tea-tree swamp, with rich vegetation, but without water. The creek, which we followed down for two miles, there changed its character, and meandered through sandy, well-grassed flats, and contained some good water-holes, on which we encamped. John told me that he had found the ripe fruit of Exocarpus cupressiformis; which I doubted very much, as I had not seen the slightest trace of it since we left the Dawson, although Exocarpus latifolia was very frequent all over the sandy table-land. But we gathered and ate a great quantity of gibong (the ripe fruit of Persoonia falcata), and some small yellow figs of the glossy-leaved fig-tree. I observed a Eucalyptus of rather stunted growth, with broad, almost oval leaves, and long, narrow seed-vessels.
During the night, thunder clouds and lightning were seen in every direction; and the whole atmosphere appeared to be in a state of fermentation. Heavy showers poured down upon us; and our tarpaulings, which had been torn to pieces in travelling through the scru
