At five miles we entered a wood of pinetrees (callitris) the first we had seen since we left the Namoi; but on passing through it we discovered no other change. A thick wood of Acacia pendula fell next in our way, and then several patches of casuarinae. On approaching one of these I observed a very slight hollow and, on following it to the right, or eastward, about a mile (the party having in the meantime halted) I perceived a few dry leaves in a heap, as if gathered by water falling in that direction. WATER DISCOVERED BY MY HORSE. Trifling as this circumstance was it was nevertheless unusual on that level surface, and I endeavoured to trace the slope downwards until my horse, who at other times would neigh after his companions, here pulled hard on the rein, as if to cross a slight rise before me. I laid the bridle on his neck while he proceeded eagerly forward over the rise, and through some wood, beyond which my eyes were once more blessed with the sight of several ponds of water, with banks of shining verdure, the whole extended in a line which resembled the bed of a considerable stream. I galloped back with the good news to the party whose desperate thirst seemed to make them incredulous, especially as I continued our line of route northward until it intercepted, at about a mile on, as I foresaw it would, this chain of ponds. It was still early; but we had already accomplished a good day's journey, and we could thus encamp and turn our cattle to browse on the luxuriant verdure which surrounded these ponds. They were wide, deep, full, and close to each other, being separated only by grassy intervals resembling dykes. NATIVE WEIRS FOR CATCHING FISH. Drift timber and other fluviatile relics lay high on the banks, and several weirs for catching fish, worked very neatly, stood on ground quite dry and hard. Lower down, as indicated by the flood-marks, the banks were much more broken, and the channel seemed deeper, while enormous bluegum-trees (eucalypti) grew on the banks, and I was therefore of opinion that some larger river was before us at no great distance. I did not explore this channel further, being desirous to refresh my horses and rest the party for continuing our journey next morning. In the soil here the only rock I found was a large, hard boulder, being a conglomerate of pebbles and grains of quartz, cemented by decomposed felspar or clay. Latitude 29 degrees 9 minutes 51 seconds South. ARRIVE AT A LARGE AND RAPID RIVER. January 23.
