The country towards the other ranges eastwards appeared poor and scrubby. We went first to a hill a good deal south of east, and crossed the dry bed of a broad, sandy, and stony creek running north. I called it the Rebecca. From it we went to a low saddle between two hills, all the while having a continuous range to the north; this was the extension beyond the pinnacle of the wall-like crescent. A conspicuous mount in this northern line I called Mount Sargood*. From this saddle we saw a range of hills which ran up from the south-west, and, extending now eastwards, formed a valley nearly in front of us. I called this new feature the Petermann Range. In it, a peculiar notch existed, to which we went. This new range was exceedingly wall-like and very steep, having a serrated ridge all along; I found the notch to be only a rough gully, and not a pass. We continued along the range, and at four miles farther we came to a pass where two high hills stood apart, and allowed an extremely large creek--that is to say, an extremely wide one--whose trend was northerly, to come through. Climbing one of the hills, I saw that the creek came from the south-west, and was here joined by another from the south-east. There was an exceedingly fine and pretty piece of park-like scenery, enclosed almost entirely by hills, the Petermann Range forming a kind of huge outside wall, which enclosed a mass of lower hills to the south, from which these two creeks find their sources. This was a very extraordinary place; I searched in vain in the pass for water, and could not help wondering where such a watercourse could go to. The creek I called the Docker*. The pass and park just within it I called Livingstone Pass and Learmonth* Park. Just outside the pass, northerly, was a high hill I called Mount Skene*. (ILLUSTRATION: VIEW ON THE PETERMANN RANGE.)
