consist of trap, porphyry, sandstone, and quartz, and show marks of being water-worn. A range of hills, apparently sandstone, bounds the valley to the east from three to seven miles from the river. They have no great elevation, and we did not obtain a good view of them from any point. Latitude by Capella 20 degrees 52 minutes 25 seconds. 1st November. The horses had strayed so far into the scrub in search of grass that it was 9.40 a.m. before they were collected and saddled; we then steered south-west through the scrub, which gradually became more open, and at 11.15 we again reached the river coming from the south-south-east; it gradually turned to south and south-south-west; two creeks joined the river from the east, but neither of any importance; the brigalow scrub came close to the bank of the river, only leaving a narrow flat open; the west side of the river we could see but little, except that it consisted of wooded ridges and scrub to the east at a distance of one to three miles; rocky hills of moderate height existed, and from their flat tops and red cliffs near the summit, evidently consisted of sandstone in horizontal strata; sandstone was also exposed near the river with a dip of 30 degrees to the south; at 3.30 camped on the right bank of the Suttor, where a fine grassy plain extended about a mile back, and was covered with beautiful green grass; water was abundant, as the river had been running during the past week and had filled the hollows in the channel, though it had now ceased to flow; the bed is very irregular, and consists of three to six channels, which separate and rejoin so as to form a complete network, with occasional isolated hollows. Being free from scrub, the bed of the river was good travelling ground, large flooded-gum trees and melaleuca-trees affording an agreeable shade. Latitude by a Pegasi 21 degrees 4 minutes 43 seconds. 2nd November (Sunday). Grass and water being abundant, we enjoyed a day's rest. Several cockatoos were shot; they are similar in colour and form to the sulphur-crested cockatoos of the Victoria and Gulf of Carpentaria, but much larger in size.
