latitude of our camp was 24 degrees 54 minutes 19 seconds, and about seven miles from our last camp. Aldis's Peak bore N.W. by W., distant two miles and a half; and I found that it was surrounded by a dense scrub. After following Zamia Creek for some miles, I turned to the left, and travelled about north-north-west, when the scrub opened, and we came upon open ridges, and, at about a mile and a half from the river, found some fine lagoons. The ridges, which are spurs of Aldis's Peak and Expedition Range, disappear in the level country to the north-east. Farther on to the north-north-west, I passed some fine plains, having the black soil, the vegetation, the dry creeks and watercourses, of Darling Downs. Thick scrub seems to extend all along the foot of the range, from Aldis's Peak to Mount Nicholson. Both these mountains are composed of basalt, containing numerous crystals of peridot.
Dec. 8.--I travelled with my whole party over the ground which I had reconnoitred yesterday, and had to go a considerable distance farther to find water. Along the scrubs there are generally chains of water-holes, which retain the water for a long time, and are soon filled by heavy thunderstorms; they are well puddled with clay, and, therefore, become dry almost exclusively by evaporation. Our camp was about eight miles N.N.W. from the last.
The feed was all parched up: the native carrot, which was so green when we passed Darling Downs, was here withered and in seed. Immense stretches of forest had been lately burned, and no trace of vegetation remained. Partridge-pigeons were very numerous, and the tracks of kangaroos and wallabies were like sheep-walks. Charley saw an emu; but an iguana and a partridge-pigeon were the only addition to our night's mess.
The sky was covered by a thin haze, occasioned by extensive bush fires. A fine breeze, which sprung up at eleven o'clock, from the northward, made travelling very agreeable. We enjoy no meal so much as our tea and damper at luncheon, when we encamp between twelve and two o'clock. It is remarkable how readily the tea dispels every feeling of fatigue, without the slightest subsequent injury of health.
Paludinas and Unios were very frequent in the water-holes. The silver-leaved Ironbark (Eucalyptus pulverulentus) was here coming into blossom. The whole vegetation seemed to feel the heat of an almost vertical sun; and, with the exception of the fresh green of the Vitex shrub, the silver-leaved Bricklow, and those patches of young grass which had been burnt about a month before--all nature looked withered. It was very hot from nine o'clock to eleven, when the cooling northerly breeze usually sets in.
Upon reaching the place of our next camp, Mr. Roper went to cut tent-poles, but, perhaps too intent on finding good ones, unfortunately lost his way, and wandered about the bush for about five miles before we were able to make him hear our cooees. Accidents of this kind happen very easily in a wooded country, where there is no leading range or watercourse to guide the rambler, or when sufficient care is not taken to mark and keep the direction of the camp.
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.
Dec. 10.--Accompanied by Charley, I went in search of a passage over the range. We ascended several hills in order to obtain general views, and found that the level country, over which we had travelled during the last two days, was of less extent than I had anticipated. To the north-east by east, ranges rise with the characteristic outlines of the basalt and phonolite,--in peaks and long stretched flat-topped hills, with undulations openly timbered extending at their base. One valley descended to the north-north-east; another to the northward. The principal range has a direction from south-west to north-east; it is flat on the top, is well grassed and openly timbered; but, to the northward, it becomes scrubby, and also changes its geological character. After having crossed the range--without any great difficulty, with the exception of some steep places--we came on gullies going down to the north-west; and, from the rocky head of one of them, the whole country to the west and northwest burst upon us. There was a fine valley, a flat country, plains, isolated long-stretched hills, and distant ranges; the highest points of the latter bearing 77 degrees E. and 76 degrees W.; and, as I hoped to reach them by Christmas time, I called them "Christmas Ranges." Not being able to discover a good slope on which our bullocks could travel, I descended at once into the gully, and followed it in all its windings; knowing well from experience that it is easier to find a passage up a mountain range than down it. The gully had all the characters of those of the Boyd; the same sandstone rock, the same abruptness, and the same vegetation; excepting, perhaps, a new Grevillea, with pinnatifid leaves and yellowish-white woolly flowers, which we found here. There was no water, except in some small holes full of gum leaves, which had rendered it unfit for use. After proceeding with great difficulty about three miles, we found that the gullies opened into a broad flat valley; in which fields of fat-hen, the Croton shrub, the native Tobacco, Erythrina, fine specimens of flooded-gum, Tristania, and the Moreton Bay ash, were growing in great abundance. Farther down, however, the Bricklow scrub covered the whole valley; the water-course disappeared almost entirely; and we were completely disappointed in our hopes of finding a fine country. Small plains opened on both sides of the valley, surrounded by Bricklow scrub, and with patches of Bricklow scattered over them, in which the Bottle-tree frequently made its portly appearance. A large flight of Wonga Wonga pigeons were feeding on the seeds of various species of Acacia; we shot two of them. No water was to be found in an extent of fifteen miles. The noisy call of the laughing Jackass (Dacclo gigantea) made me frequently ride back and examine more minutely those spots marked by a darker foliage; but the presence of this bird is no certain indication of water, though he likes the neighbourhood of shady creeks. I could not help thinking that a considerable creek must come from the north-west side of Mount Nicholson; and, seeing an isolated range to the south-west, I rode towards it, sure of finding water near it, if there was any to be found. We approached the range just before sunset, much tired, with two Wonga-Wongas and three iguanas at our saddles. I had just informed my Blackfellow, that I wished to encamp, even without water, when some old broken sheets of bark, remains of the frail habitations of the natives, caught my eye; a dry water-hole, though surrounded with green grass and sedges, showed that they had formerly encamped there, with water. This water-hole was found to be one of a chain of ponds extending along the edge of the scrub which covered the hill; and, on following it farther down, we came to a fine pool of water, which enabled us to encamp comfortably. Next morning, after having enjoyed an iguana, and finding several other ponds well supplied with water, we returned. In crossing several of the scrub plains before mentioned, it was agreeable to observe that the dense vegetation which covered them was not the miserable Burr and the wiry Vervain,
