18TH DECEMBER.--The party moved off about 7 A.M., and continued along a tolerable road, crossing what shepherds called Seven Mile Creek, in which there was some water; and a little further on we quitted the good beaten road leading to Balderudgery, and followed one to the left, which brought us to another sheep station on the same chain of ponds, three miles higher up than Balderudgery. Having directed the party to encamp here, I pursued the road south-westward along the chain of ponds, anxious to ascertain whether I could in that direction pass easily to the westward of Hervey's Range, and so fall into my former line of route to the Bogan. At about five miles I found an excellent opening through which the road passed on ground almost level. Having ascended a small eminence on the right, I fell in with some natives with spears, who seemed to recognise me, by pointing to my old line of route, and saying, "Majy Majy" (Major Mitchell). I little thought then that this was already an outlying picquet of the Bogan Blacks, sent forward to observe my party. The day was hot, therm. 97 deg. in the shade. The chain of ponds, there called "the Little River," contained water in abundance, and was said to flow into the Macquarie, in which case the Bogan can have but few sources in Hervey's Range. The station beside which we had encamped, comprised a stock yard, and had been formerly a cattle station belonging to Mr. Kite. It was now a sheep station of Dr. Ramsay's, and there was another sheep station a mile and a half from it, along the road I had examined. Thus the country suitable for either kind of stock is taken up by the gradual encroachment of sheep on cattle runs, not properly such. This easily takes place--as where sheep feed, cattle will not remain, and sheep will fatten where cattle would lose flesh. Fortunately, however, for the holders of the latter description of stock, there are limits to this kind of encroachment. The plains to the westward of these ranges afford the most nutritive pasturage in the world for cattle, and they are too flat and subject to inundations to be desirable for sheep. A zone of country of this description lies on the interior side of the ranges, as far as I have examined them. It is watered by the sources of the rivers Goulburn, Ovens, Murray, Murrumbidgee, Lachlan, Bogan, Macquarie, Castlereagh, Nammoy, Peel, Gwydir, and Darling; on which rivers the runs will always make cattle fat. There are two shrubs palpably salt, and, perhaps, there is something salsolaceous in the herbage also on which cattle thrive so well; and the open plains and muddy waterholes are their delight. Excessive drought, however, may occasionally reduce the owners of such stock to great extremities, and subject them to serious loss. The Acacia pendula, a tree whose HABITAT is limited and remarkable, is much relished by the cattle. It is found only in clay soils, on the borders of plains,
