Resumed the journey at 6.20 a.m., steering south down the watercourse; at 7.0 saw some blacks, who, when asked by signs where water could be found, pointed down the creek and into the scrub; at 9.20 came to a pool of rainwater and camped. This part of the country is very poor and scrubby, with large Moreton-Bay ash trees, the soil formed by the decomposition of sandstone and conglomerate, with intervals of schist and trap-rock. CROSS THE PEAK DOWNS. 14th November. At 6.50 a.m. steered south-east; we soon entered a grassy plain with ironbark ridges and belts of acacia scrub, trap, and limestone on the plains, and sandstone on the ridges; at noon passed a belt of cypress and entered extensive open downs covered with beautiful green grass. Following a shallow watercourse, passed some blacks at a distance, and at 4.20 p.m. came to a small pool of rainwater, and camped. The country to the north-east appeared level, and the grassy downs apparently extend to the foot of Peak Range. To the south-west it appeared to be a fine open country for three to eight miles, and then rose into wooded hills of moderate elevation, at the base of which a creek appeared to run to the south-east. If this part of the country were well supplied with water it would form splendid stations for the squatter; but from its level character and geological structure, permanent surface-water is very scarce, and where it does exist it is surrounded by scrubby country, which renders it almost unavailable. THE MACKENZIE RIVER. 15th November. At 6.40 steered east-south-east and soon entered an open acacia scrub with some grassy patches; the soil a fine black loam; limestone, trap, and quartz-pebbles occurring on the surface in the open plain; at 9.0 entered a fine box flat, and passed some pools of water; the flat extending east three miles; then entered a scrubby tract of country, the soil a black mould with much salsola growing even in the thick scrub; at 11.0 came on a fine creek from the north with pools of permanent water (Crinum Creek), but the banks covered with scrub. Changing the course to south-east, at 12.20 p.m. came to a fine river with high grassy banks and several deep channels which were now full of water and running in consequence of the late rains. It had been slightly flooded this season, and the previous year had risen twenty-five feet above the present level. This river is the Mackenzie of Leichhardt. The course of the river is to the east-south-east, and we crossed to the right bank without much difficulty, the bottom being firm and the bank sandy; followed the river till 2.40, and camped. The country on the banks of the Mackenzie is scrubby, with occasional open flats; the timber box, with good grass. The little lemon-tree was in full bearing, and though the fruit is only half an inch in diameter, was excellent eating when boiled with sugar. The day was cool and cloudy, and it rained lightly for some hours during the night.
