We passed a very large plain in the course of the day, which was bounded by forests of box, cypress, and the acacia pendula, of red sandy soil and parched appearance. The Morumbidgee evidently overflows a part of the lands we crossed, to a greater extent than heretofore, though the alluvial deposits beyond its influence were still both rich and extensive. The crested pigeon made its appearance on the acacias, which I took to be a sure sign of our approach to a country more than ordinarily subject to overflow; since on the Macquarie and the Darling, those birds were found only to inhabit the regions of marshes, or spaces covered by the acacia pendula, or the polygonum. We had not, however, yet seen any of the latter plant, although we were shortly destined to be almost lost amidst fields of it. CHANGE IN THE COUNTRY. We were now approaching that parallel of longitude in which the other known rivers of New Holland had been found to exhaust themselves; the least change therefore, for the worse was sufficient to raise my apprehensions; yet, although the Morumbidgee had received no tributary from the Dumot downwards, and was leading us into an apparently endless level, I saw no indication of its decreasing in size, or in the rapidity of its current. Certainly, however, I had, from the character of the country around us, an anticipation that a change was about to take place in it, and this anticipation was verified in the course of the following day. The alluvial flats gradually decreased in breadth, and we journeyed mostly over extensive and barren plains, which in many places approached so near the river as to form a part of its bank. They were covered with the salsolaceous class of plants, so common in the interior, in a red sandy soil, and were as even as a bowling green. The alluvial spaces near the river became covered with reeds, and, though subject to overflow at every partial rise of it, were so extremely small as scarcely to afford food for our cattle. Flooded-gum trees of lofty size grew on these reedy spaces, and marked the line of the river, but the timber of the interior appeared stunted and useless.
