It was quite dark on the evening of the 26th, before I reached the inn near the head of the little valley of the Wollombi, a tributary to the river Hunter. Here, at length, we again find some soil fit for cultivation, and the whole of it has been taken up in farms. But the pasturage afforded by the numerous valleys on this side of the mountains, here called cattle runs, is more profitable to the owners of the farms, than the farms they actually possess, of which the produce by cultivation is only available to them at present, as the means of supporting grazing establishments. I should here observe, that in a climate so dry as that of Australia, the selection of farmland depends solely on the direction of streams, for it is only in the beds of watercourses, that any ponds can be found during dry seasons. The formation of reservoirs has not yet been resorted to, although the accidental largeness of ponds left in such channels has frequently determined settlers in their choice of a homestead, when by a little labour, a pond equally good might have been made in other parts, which few would select from the want of water. In the rocky gullies, that I had passed in these mountains, there was, probably, a sufficiency, but there was no land fit for the purposes of farming. In other situations, on the contrary, there might be found abundance of good soil, considered unavailable for any purpose except grazing, because it had no frontage (as it is termed) on a river or chain of ponds. Selections have been frequently made of farms, which have thus excluded extensive tracts behind them from the water, and these remaining consequently unoccupied, have continued accessible only to the sheep or cattle of the possessor of the water frontage. In these valleys of the Upper Wollombi, we find little breadth of alluvial soil, but a never-failing supply of water has already attracted settlers to its banks--and those smallfarmers who live on a field or two of maize and potatoes--and who are the only beginning of an agricultural population, yet apparent, in New South Wales--show a disposition to nestle in any available corner there. But on the lower portion of the Wollombi, where the valley widens, and water becomes less abundant, the soil being sandy, I found it impossible to locate some veterans on small farms, which I had marked out for them, because it was known that in dry seasons, although each farm had frontage on the Wollombi Brook, very few ponds remained in that part of its channel. JOIN THE PARTY. November 27. Early this morning, I had a visit from Mr. Finch, who was very anxious that I should attach him to the exploring party. As I foresaw, that some delay might occur in procuring provisions, without his assistance, in this district, I accepted his services, and gave him his instructions, conditionally. I met Mr. White at the junction of the Ellalong, and we proceeded together, down the valley of the Wollombi.
