19TH SEPTEMBER.--The thermometer at 7 A.M. stood at 57 deg.. The height of these ponds above the sea was 861 feet. Young, I think, has said, that a situation might be imagined between earth and heaven, where a man should hear nothing but the thoughts of the Almighty; but such a sublime position seems almost attained by him who is the first permitted to traverse extensive portions of earth, as yet unoccupied by man; to witness in solitude and silence regions well adapted to his use, brings a man into more immediate converse with the Author both of his being, and of all other combinations of matter than any other imaginable position he can attain. With nothing but nature around him; his few wants supplied almost miraculously; living on from day to day, just as he falls in with water; his existence is felt to be in the hands of Providence alone; and this feeling pervades even the minds of the least susceptible, in journeys like these. Those splendid plains where, without a horse, man seems a helpless animal, are avoided, and are said to be shunned and disliked by the aboriginal man of the woods. Even their lonely inhabitant, the emu, seems to need both wings and feet, that he may venture across them. We travelled nearly west over plains; then through a brigalow scrub, two miles in breadth; emerging from which, on a perfectly level plain of very rich soil, we turned rather to the southward of west, to where the distant line of river-trees seemed most accessible. Bushes of ACACIA PENDULA skirted this plain; and, passing through them, we crossed a track of nearly half a mile wide of soft sand, evidently a concomitant feature of the river. We next traversed a belt of firm blue clay, on which a salsolaceous bush appeared to be the chief vegetation; and, between it and the river, was another belt of sand a mile broad, on which grew a scrub of rosewood acacia. The river there ran in four separate channels, amongst various trees; brigalow and yarra being both amongst them. I crossed these channels, and continued westward that I might ascend a hill on the downs beyond. From that eminence, no hill was visible on any part of the horizon, which everywhere presented only downs and woods. Far in the S.W. a hollow admitted of a very distant view, which terminated in downs beyond a woody valley. The course of our river appeared to be N.W., as seen by Yuranigh, from a tree we found here. In that direction I therefore proceeded; recrossing the river, where, in a general breadth of about 400 yards, it formed five channels. The grass was more verdant here, and the ponds in these small separate channels seemed likely to contain water. We continued N. W. across fine clear downs, where we found the heat so intense, (Centigrade thermometer, 37 deg., or 99 deg. of Fahrenheit,) that I halted two hours under the shade of a small clump of trees. When we continued our ride in the afternoon, three emus that had been feeding on the downs came inquisitively forward; curiosity,
