The inclination of the loftier trees, particularly the cypress trees, for these two or three days past, denoted the strength and prevalence of the south-west and westerly winds: this is more easily discernible from the tops of low ranges; the western side of the tree being generally deprived of its branches, and the trunk bent in a remark-able manner to the north-east. This inclination and prevalence of the winds was not observed in any particular degree westward of Mount Cunningham, and was most remarkable in that elevated range of country lying between the depot on the Lachlan and Bathurst; and which elevated tract continues with little interruption to the western base of the Blue Mountain range, on which there is not a single tree that does not denote prevalence of the westerly wind. August 13.--Again set forward, intending to keep a north-easterly course through the day, when if we do not fall in with the river, our future course will be directed more easterly; as we shall be then full seventy miles north of Bathurst, and north of the parallel of Port Stephens. The country through which our course led us to-day was of various description, the first three miles and a half being indifferent forest land, open with respect to timber, but much overrun with small acacia bushes; at the end of this tract was a small stream of water in ponds, having its course in the lofty range east-south-east of us, and which was not very distant from us; this stream was named Allan Water, and its stream was northerly. The next four miles north-east of this burn was through a barren scrubby country, full of dry water-holes, and thickly covered with the casuarina filifolia, box trees, and acacia bushes. The cypress seemed to shun this kind of barren clayey soil, and was more prevalent and flourishing on the open forest land where the soil was light and loamy, and covered with luxuriant broom-grass; this was the case for the last few miles, which consisted of a very good tract of land. The cypresses here grew into very handsome timber, and indeed were the only useful wood, as the box tree was usually stunted and crooked. At the end of twelve miles we found a small spring of water that supplied some ponds, which also run northerly. The grass being pretty good, although old, we determined to halt for the evening, as the horses were not all arrived having had a considerable detour to make in crossing Allan Water. On the banks of that burn many heaps of the pearl muscle-shells were found, and marks of flood about eight feet. We have for several days past seen no signs of any natives being recently in this part of the country; the marks on the trees, which were the only marks we saw, being several months old, and never seen except in the vicinity of water. Marks of the natives' tomahawks were to us certain signs of approaching water.
