Heavy clouds gathered during the afternoon of the 6th, and it rained throughout the night; the wind was from N. and N.E. In the morning of the 7th some drops of rain fell, but the weather cleared up during the day; wind easterly. The moon changed this day, and we experienced a heavy thunder-storm during the afternoon. April 8.--We travelled about nine miles N. 70 degrees W., to latitude 20 degrees 9 minutes 11 seconds. The river made a bend to the southward, and then, at a sharp angle, turned again to the north-west. At this angle a large creek joined it from the south; another instance of creeks joining larger channels, coming in a direction almost opposite to their course. Two other creeks joined the Burdekin during this stage; one from the south-west, and another from the north. The grass was particularly rich at these junctions. The river became considerably narrower, but still had a fine stream. Thunder-storms had probably fallen higher up its course, causing a fresh; for its waters, hitherto clear, had become turbid. Narrow patches of brush were occasionally met with along its banks, and I noticed several brush trees, common in other parts of the country. Besides the clustered fig, and another species with rough leaves and small downy purple fruit, there were a species of Celtis; the Melia Azederach (White Cedar); a species of Phyllanthus, (a shrub from six to ten feet high); an Asclepiadaceous climber, with long terete twin capsules; and several Cucurbitaceae, one with oblong fruit about an inch long, another with a round fruit half an inch in diameter, red and white, resembling a gooseberry; a third was of an oblong form, two inches and a half long and one broad; and a fourth was of the size and form of an orange, and of a beautiful scarlet colour: the two last had an excessively bitter taste. The night and morning were cloudy, with a southerly wind, but it cleared up at eleven o'clock. Cumuli in the afternoon, with wind from the south-east. From our camp we saw a range of hills, bearing between N. 5 degrees W. and N. 10 degrees W.; they were about three miles distant. I called them "Thacker's Range," in acknowledgment of the support I received from--Thacker, Esq., of Sidney.
