I beg you will inform His Excellency the Governor, that I have on all occasions received the most ready and valuable assistance from Mr, Hume. His intimate acquaintance with the manners and customs of the natives, enabled him to enter into intercourse with them, and chiefly contributed to the peaceable manner in which we have journeyed, while his previous experience put it in his power to be of real use to me. I cannot but say he has done an essential service to future travellers, and to the colony at large, by his conduct on all occasions since he has been with me; nor should I be doing him justice, if I did not avail myself of the first opportunity of laying my sentiments before the Governor, through you. I am happy to add that every individual of the party deserves my warmest approbation, and that they have, one and all, borne their distresses, trifling certainly, but still unusual, with cheerfulness, and that they have at all times been attentive to their duty, and obedient to their orders. The whole are in good health, and are eager again to start. I have the honor to be, Sir Your most obedient and most humble servant, CHARLES STURT, Capt. 39th Regt.

SIR,--It having appeared to me, that after discovering such a river as the one I have described in my letter of yesterday, His Excellency the Governor would approve of my endeavouring to regain it. There being a probability that it ultimately joins the Southern Waters, I thought of turning my steps to the southward and westward; and with a view to learn the nature of the country, I despatched Mr. Hume in that direction on Saturday last. He returned in three days, after having gone above forty miles from the river, and states, that he crossed two creeks, the one about twenty-five miles, the other about thirty-two distance, evidently the heads of the creeks we passed westward of the marshes of the Macquarie. He adds, that, to the second creek the land was excellent, but that on crossing it, he got onto red soil, on which he travelled some miles further, until he saw a range of high land, bearing from him S.W.. by W., when, knowing from the nature of the country around him, and from the experience of our late journey, that he could not hope to find a regular supply of water in advance, and that in the present dry state of the low lands, a movement such as I had contemplated would be impracticable, he returned home. I do myself the honour, therefore, to report to you, for His Excellency's information, that I shall proceed on Saturday next in a N.E. direction towards the Castlereagh, intending to trace that river down, and afterwards to penetrate as far to the northward and westward as possible; it being my wish to get into the country north of the more distant river, where I have expectations that there is an extensive and valuable track of country, but that in failure of the above,
