Dec. 9.--The haze of yesterday cleared up at sunset, after having formed two threatening masses of clouds in the east and in the west, united by a broad belt of mare's tails across the sky. It became cloudy again, and prevented my taking observations during the night; the morning was cool and agreeable, clearing up about eleven o'clock; the northerly wind stirring, as usual. Proceeding on our journey, we travelled about nine miles W.N.W. over a Box flat, with stiff soil and melon-holes; after a few miles, it changed into an open silver-leaved Ironbark forest, with lighter soil. About six miles from our last camp, we came upon a fine creek (with Casuarinas and palm-trees), flowing from the mountains on a north-easterly course; and, about three miles further, to the W.N.W., we came to another creek, and numerous palm-trees growing near it. Following up the latter, we found a fine water-hole surrounded by reeds, and which is probably fed by a spring. The forest was well grassed; and a small Acacia, about fifteen or twenty feet high, with light green bipinnate leaves (from which exuded an amber-coloured eatable gum), formed groves and thickets within it. A Capparis, a small stunted tree, was in fruit: this fruit is about one inch long and three-quarters of an inch broad, pear-shaped and smooth, with some irregular prominent lines. Capparis Mitchelii has a downy fruit, and is common in the scrubs. A small trailing Capparis, also with oblong eatable fruit, was first observed on a hill near Ruined Castle Creek, in lat. 25 degrees 10 minutes: we met with it frequently afterwards. We were encamped in the shade of a fine Erythrina; and the Corypha-palm, Tristania, the flooded-gum, the silver-leaved Ironbark, Tripetelus, and a species of Croton, grew around us. A species of Hypochaeris and of Sonchus, were greedily eaten by our horses; the large Xeranthemum grew on the slopes, among high tufts of kangaroo grass. A species of Borage (Trichodesma zeylanica), with fine blue flowers, was first seen here; and the native raspberry, and Ficus muntia, were in fruit. In the afternoon, I went with Brown up the range, following the bed of our creek; and, having ascended a spur of sandstone, with gullies on each side, we came to a large basaltic mountain, clothed with fine open timber, and a great number of arborescent Zamias.
