September 7.--The morning clear and fine. At half past seven o'clock we proceeded on our journey: in the whole course of it, we never experienced more precipitous travelling than during the first six miles. Travellers, less accustomed to meet difficulties, might perhaps have been a little alarmed at traversing such steep and shelving hills, the loose stones on which added to the insecurity of our footing. Nevertheless we found it extremely pleasant, from the romantic beauty of the scenery and the freshness of the verdure. We had been ascending an extremely elevated country for the last thirty miles; and I was in great hopes of soon reaching the point of division between the eastern and western waters. By a tolerably easy acclivity, we gained that which I took to be the highest of these congregated hills, in hopes it might possibly lead into a main range. From its summit we had a very extensive prospect over the country we had left, and also to the southward, in which direction the land appeared broken and hilly, and but thinly clothed with timber. To the east and north-east it appeared far less broken, and certainly less elevated than the ridge we were on. This ridge soon expanded to a broad surface of open forest land, and proceeding on it to the east about a mile, we perceived in the valley beneath us a considerable and rapid stream running to the north, and afterwards apparently taking a more easterly direction. A more remarkable change in the outward appearance of a country was perhaps never before witnessed. In less than a mile, the timber had entirely changed from the bastard box to another kind of eucalyptus, called common blue gum, which grew in great luxuriance in the country before us. Until now this species had never been seen except on the immediate banks of running streams. In the course of the day, great quantities of fine stringy bark were also seen. The soil, instead of the light black mould, which had been the general covering of the country, was now changed to a stiff tenacious clay; and although well clothed with grass, its less luxuriant growth evidently showed the difference of soil not to be favourable. From this hill or range we descended very gradually for nearly two miles to the river before seen, and up the banks of which we proceeded about a mile farther, when we halted for the evening. The country was perfectly open, though much covered with fallen timber; the banks of the river sloping and quite clear of timber; and being within one hundred miles of the sea coast, I had a strong belief that we had descended from the highest land, and that we should meet with no dividing ranges in the course of our future progress. It is impossible to form any certain conclusion at present, as to the course taken by this stream. Whether it finds its way to the coast, or is lost like the other streams of this country, will, I think, in a great measure depend upon the fact of our having crossed the highest ranges of the country.
