At 6.15 a.m. steered south and followed the right bank of the river; for the first hour the country was hilly on both banks, with deep gullies; it then became more level, and opened into flats, well grassed; the timber box, ironbark, and Moreton-Bay ash; the soil a light brown loam in some parts, sandy and very soft from the numerous excavations of the funnel ant. These flats extended one to two miles back and then rose into low ridges of poor land, timbered with box and ironbark; crossed a sandy creek coming from the west, and at 1.30 p.m. camped on the right bank of the river. A short distance from the camp surprised a black and his gin and a child; the man climbed a tree and the woman ran off with the child, leaving a small water vessel, hollowed out of a piece of wood, and a calabash full of water. The rocks near the last camp were sandstone or porphyry; in the only exposed section the sandstone dipped to the north 5 degrees to 15 degrees. We also crossed a hill of porphyry which was remarkable for the regularity of cleavage into thick lamina, which were vertical, with a north and south strike; but though it had the appearance of a stratified rock, its structure was perfectly crystalline. About noon, granite, containing large plates of mica, was observed in some of the gullies. Latitude by e Pegasi 19 degrees 29 minutes 43 seconds. 23rd October. At 7.0 a.m. steered south-south-east and south-east over ridges of sandstone, timbered with ironbark and thinly grassed, for an hour and a half; again struck the river and passed at the foot of some limestone hills and ridges; this limestone contained fragments of shells and coral. Altering the course to south, traversed fine open flats half a mile to a mile wide, beyond which the country rose into low ridges of limestone. At noon basalt appeared covering the limestone and sandstone. The steep slope which formed the boundary of this rock was very rugged; but the level surface was covered with black soil and well grassed. At 12.55 p.m. camped in a fine grassy flat, walled in by steep rocks of basalt. We experienced some difficulty in watering the horses, as the bank of the river was so steep that they frequently fell back into the river in ascending it. The limestone rocks seen on this day's journey appear to rise from beneath the sandstones, some of which are very hard and close-grained; it dips about 10 degrees to the west and some of the adjacent sandstones 20 degrees west, in well-defined strata. The basalt covers all the other rocks, filling up the former inequalities of the surface and forming a perfectly level plain; where the softer sandstones were in contact, they were only baked into a coarse brick-like mass, which had had much the appearance of having been formed from the alluvial banks of the river. Latitude by e Pegasi and a Gruis 19 degrees 42 minutes 10 seconds; variation of compass 6 degrees 15 minutes east. DUCKS, GEESE, AND PELICANS. 24th October.
