We travelled about eleven miles in a S. W. and S. S. W. direction, skirting the scrub. During the journey, two thunder-storms passed over; one to the southward beyond the Condamine, the other to the north and north-east over the mountains. The scrub is a dense mass of vegetation, with a well defined outline--a dark body of foliage, without grass, with many broken branches and trees; no traces of water, or of a rush of waters. More to the southward, the outline of the scrub becomes less defined, and small patches are seen here and there in the forest. The forest is open and well timbered; but the trees are rather small. A chain of lagoons from E. by N.--W. by S.; large flooded gum-trees (but no casuarinas) at the low banks of the lagoons. The presence of many fresh-water muscles (Unio) shows that the water is constant, at least in ordinary seasons. The scrub opens more and more; a beautiful country with Bricklow groves, and a white Vitex in full blossom. The flats most richly adorned by flowers of a great variety of colours: the yellow Senecios, scarlet Vetches, the large Xeranthemums, several species of Gnaphalium, white Anthemis-like compositae: the soil is a stiff clay with concretions: melon-holes with rushes; the lagoons with reeds. At night, a thunder-storm from south-west. Our dogs caught a female kangaroo with a young one in its pouch, and a kangaroo rat. Oct. 5.--We followed the chain of lagoons for about seven miles, in a west by south direction; the country to our right was most beautiful, presenting detached Bricklow groves, with the Myal, and with the Vitex in full bloom, surrounded by lawns of the richest grass and herbage; the partridge pigeon (Geophaps scripta) abounded in the Acacia groves; the note of the Wonga Wonga (Leucosarcia picata, GOULD.) was heard; and ducks and two pelicans were seen on the lagoons. Blackfellows had been here a short time ago: large unio shells were abundant; the bones of the codfish, and the shield of the fresh-water turtle, showed that they did not want food. A small orange tree, about 5-8 minutes high, grows either socially or scattered in the open scrub, and a leafless shrub, belonging to the Santalaceae, grows in oblong detached low thickets. Chenopodiaceous plants are always frequent where the Myal grows. The latitude of our camp was 26 degrees 56 minutes 11 seconds. Oct. 6.--Was fully occupied with mending our packsaddles and straps, broken by the bullocks in throwing off their loads. Oct. 7.--In following the chain of lagoons to the westward, we came, after a few miles travelling, to the Condamine, which flows to the north-west: it has a broad, very irregular bed, and was, at the time, well provided with water--a sluggish stream, of a yellowish muddy colour, occasionally accompanied by reeds. We passed several gullies and a creek from the northward, slightly running.
