16TH OCTOBER.--A clear cool morning, with a fine refreshing breeze from east, succeeded the cloudy weather of yesterday. I crossed the little river, and travelled straight towards Camp XXXVII. On the higher ground grew a heath-like bush, (ERIOSTEMON RHOMBEUM,) three or four feet high. At a distance of only nine miles, we came upon the little river beside that camp, and fell into the old track a mile on beyond it; and, early in the day, we arrived at a chain of ponds, half-way to the next camp at Possession Creek. The ponds where I went to encamp were dry; but, on following the water-course downwards, I came to its junction with the Maranoa, at half a mile from the camp, and found a large basin of water at that point. Here, the NOTELOEA PUNCTATA was no longer a low trailing bush, but a shrub ten or twelve feet high, with the appearance of a European PHILLYREA. On the wet ground at the river bank, grew an entire- leaved variety (?) of PLANTAGO VARIA. The wild carrot, DAUCUS BRACHIATUS, with an annual wiry root, was also seen in the rich ground near the river. Yuranigh found more of the native tobacco, which the men eagerly asked for some of. This was a variety of the southern NICOTIANA SUAVEOLENS, with white flowers, and smoother leaves. Thermometer, at sunrise, 37 deg.; at noon, 70 deg.; at 4 P.M., 76 deg.; at 9, 51 deg.;--with wet bulb, 42 deg.. Height above the sea, 1315 feet. (Camp 75.) 17TH OCTOBER.--The thermometer stood as low as the freezing point this morning, and the day was cooled by a wind from the N. E. In crossing Possession Creck, we saw nothing of the formerly belligerent natives. From Camp XXXIII, I took a direct course to Camp XXXII, where we arrived early. No water remaining in the adjacent ponds, I followed the dry channel down to its junction, and found the Maranoa full of water; this point being three quarters of a mile from our camp. We had this day passed over a fine open forest country, in which were also groves of the ACACIA PENDULA. The vegetation, in general, seemed drooping, from the want of rain; but the whole was available for grazing purposes. We saw, this day, plants of PYCNOSORUS GLOBOSUS, in the dry forest land; and the purple-flowered RUELLIA AUSTRALIS. The ACACIA SPECTABILIS formed a spreading bush, about eight feet high. The HOVEA LEIOCARPA, and CONVOLVULUS ERUBESCENS, were also found; with a new MYRIOGYNE[*], and a small shrub, three feet high, with narrow, blunt, glaueous leaves, tasting like rum. A small fruit, with the fragrance of an orange, proved to be a new species of TRIPHASIA.[**] [* M. RACEMOSA (Hook.
