Before Leichhardt's return, Sir Thomas Mitchell had started on his long-delayed journey, which, in the main, had the same purpose in view as Leichhardt's. This expedition had been long talked of. In 1841, communications between Governor Gipps and Captain Sturt had taken place on the subject, and in December of the same year, Eyre, not long back from his journey to King George's Sound, wrote, offering his services. [See Appendix.] To this the Governor replied that he would be glad to avail himself of Mr. Eyre's services, provided that no prior claim to the post was advanced by Captain Sturt. He also desired Eyre's views as to the expense of the party. Eyre estimated that the sum of five thousand pounds would, he thought, be sufficient to fully cover every expense, including the hire of a vessel (to meet the party on the north coast), and the payment of the wages of the men and the salaries of the surveyor and draughtsman. But the colony was not in a mood to indulge in such expense, and nothing was done just then. In 1843, Major Mitchell submitted A plan of exploration to the Governor, who promised to consult the Legislative Council who approved, and voted a sum of one thousand pounds towards the expenses. The Governor referred the matter to Lord Stanley, who gave a favourable reply; but still the matter was delayed. In the beginning of the following year (1844), Eyre again made an offer of his services, intimating that now the altered circumstances of the colony would allow it to be carried through at a much cheaper rate. His offer was, however, declined, on account of the Surveyor-General, to whom the honour rightfully belonged, being in the field. In 1845, the Council increased the exploration fund to two thousand pounds, and Sir George Gipps instructed Major Mitchell to start. The views of Sir Thomas were in favour of obtaining a road to the foot of the Gulf, instead of Port Essington, on account of reducing the land journey considerably, and also there being such a reasonable probability that a large river would be found flowing northward into it. In a letter which the Surveyor-General received from Mr. Walter Bagot [See Appendix.] about this time, mention is made of the blacks reporting a large river west of the Darling, running to the north or north-west. As, however, the natives do not seem very clear in their knowledge of the difference between flowing from and flowing to, it was probable that Cooper's Creek, not then discovered by Sturt, was the foundation of the legend, or possibly the Paroo. During the earlier part of the year, Commissioner Mitchell (a son of Sir Thomas) made an exploration towards the Darling, and the discoveries of the Narran, the Balonne, and the Culgoa have been attributed to him; but, as will be seen by Bagot's letter, they were known to the settlers a year before; no special interest beyond this is to be found in the narrative of the journey.
