Geographical remarks.

In a geographical point of view, however, nothing could have been more satisfactory, excepting an absolute knowledge of the country to the northward between the Murray and the Darling, than the results of the expedition.  I have in its proper place stated, as fairly as I could, my reasons for supposing the principal junction (which I consequently left without a name) to be the Darling of my former journey, as well as the various arguments that bore against such a conclusion.

Of course, where there is so much room for doubt, opinions will be various.  I shall merely review the subject, in order to connect subsequent events with my previous observations, and to give the reader a full idea of that which struck me to be the case on a close and anxious investigation of the country from mountain to lowland.  I returned from the Macquarie with doubts on my mind as to the ultimate direction to which the waters of the Darling river might ultimately flow; for, with regard to every other point, the question was, I considered, wholly decided.  But, with regard to that singular stream, I was, from the little knowledge I had obtained, puzzled as to its actual course; and I thought it as likely that it might turn into the heart of the interior, as that it would make to the south.  It had not, however, escaped my notice, that the northern rivers turned more abruptly southward (after gaining a certain distance from the base of the ranges) than the more southern streams:  near the junction of the Castlereagh with the Darling especially, the number of large creeks joining the first river from the north, led me to conclude that there was at that particular spot a rapid fall of country to the south.

The first thing that strengthened in my mind this half-formed opinion, was the fall of the Lachlan into the Morumbidgee.  I had been told that Australia was a basin; that an unbroken range of hills lined its coasts, the internal rivers of which fell into its centre, and contributed to the formation of an inland sea; I was not therefore prepared to find a break in the chain—­a gap as it were for the escape of these waters to the coast.

Subsequently to our entrance into the Murray, the remarkable efforts of that river to maintain a southerly course were observed even by the men, and the singular runs it made to the south, when unchecked by high lands, clearly evinced its natural tendency to flow in that direction.

Had we found ourselves at an elevation above the bed of the Darling when we reached the junction of the principal tributary with the Murray, I should still have had doubts on my mind as to the identity of that tributary with the first-mentioned river; but considering the trifling elevation of the Darling above the sea, and that the junction was still less elevated above it, I cannot bring myself to believe that the former alters its course.  It is not, however, on this simple geographical principle that I have built my conclusions; other corroborative circumstances have tended also to confirm in my mind the opinion I have already given, not only of the comparatively recent appearance above the ocean of the level country over which I had passed, but that the true dip of the interior is from north to south.
