Such, there can be no doubt, have been the results of an expedition from which human foresight could have anticipated no practical good. During my progress down the Murray River I had passed the junction of a very considerable stream with it [Note 3. The Darling], in lat. 34 degrees 8 minutes and long. 142 degrees. Circumstances, however, prevented my examining it to any distance above its point of union with the main river. Yet, coming as it did, direct from the north, and similar as it was to the Darling in its upper branches, neither had I, nor any of the men then with me, and who had accompanied me when I discovered the Darling in 1828, the slightest doubt as to its identity. Still, the fact might reasonably be disputed by others, more especially as there was abundant space for the formation of another river, between the point where I first struck the Darling and this junction. It was at all events a matter of curious speculation to the world at large, and was a point well worthy of further investigation. Such evidently was the opinion of her Majesty's Government at the time, for in accordance with it, in the year 1835, Sir Thomas Mitchell, the Surveyor-General of the colony of New South Wales, was directed to lead an expedition into the interior, to solve the question, by tracing the further course of the Darling. This officer left Sydney in May, 1835, and pushing to the N.W. gradually descended to the low country on which the Macquarie river all but terminates its short course. In due time he gained the Bogan river (the New Year's Creek of my first expedition, and so called by my friend, Mr. Hamilton Hume, who accompanied me as my assistant, because he crossed it on that day), and tracing it downwards to the N. W., Sir Thomas Mitchell ultimately gained the banks of the Darling, where I had before been upon it, in latitude 30 degrees. He then traced it downwards to the W.S.W {S.S.W. in published text} to latitude 32 degrees 26 seconds. At this point he determined to abandon all further pursuit of the river, and he accordingly returned to Sydney, in consequence, as he informs us, of his having ascertained that just below his camp a small stream joined the Darling from the westward. The Surveyor-General had noticed distant hills also to the west; and it is therefore to be presumed that he here gave up every hope of the Darling changing its course for the interior, and of proving that I was wrong and that he was right. The consequence, however, was, that he left the matter as much in doubt as before, and gained but little additional knowledge of the country to the westward of the river.
