#9. Mitchell.#--Whilst Leichardt was absent on his first journey, Sir Thomas Mitchell--the discoverer of the Glenelg--had prepared an expedition for the exploration of Queensland. Having waited till the return of Leichardt, in order not to go over the same ground, he set out towards the north, and, after discovering the Culgoa and Warrego--two important tributaries of the Darling--he turned to the west. He travelled over a great extent of level country, and then came upon a river which somewhat puzzled him. He followed the current for 150 miles, and it seemed to flow steadily towards the heart of the continent. He thought that its waters must eventually find their way to the sea, and would, therefore, after a time, flow north to the Indian Ocean. If that were the case, the river--which the natives called the Barcoo--must be the largest stream on the northern coast, and he concluded that it was identical with the Victoria, whose mouth had been discovered about nine years before by Captain Stokes. He, therefore, provisionally gave it the name of the Victoria River. #10. Kennedy.#--On the return of Mitchell, the further prosecution of exploration in these districts was left to his assistant-surveyor--Edmund Kennedy--who, having been sent to trace the course of the supposed Victoria River, followed its banks for 150 miles below the place where Mitchell had left it. He was then forced to return through want of provisions; but he had gone far enough, however, to show that this stream was only the higher part of Cooper's Creek, discovered not long before by Captain Sturt. This river has a course of about 1,200 miles; and it is, therefore, the largest of Central Australia. But its waters spread out into the broad marshes of Lake Eyre, and are there lost by evaporation.
