Burnett and Piper followed the native path until they came to the bed of a fine lake about half a mile across, and they met some natives who told them that the name of it was Weromba. Mr. Stapylton also discovered a small lake of the same sort near our route and south of the other. Both sheets of water, like that of Waljeers, were surrounded by a ridge of rising ground consisting of the red earth of the dry plains, and it was covered with the salsolaceous shrubs peculiar to them. These lakes seem to be supplied only from the highest floods of the river, and to constitute a remarkable and peculiar feature in the character of the surface. I had been informed of a very large one of the same kind named Quawingame near the left bank of the Lachlan, and not far from its junction with the Murrumbidgee; but the singular turn of the first-mentioned river prevented me from seeing it. NATIVE ENCAMPMENT. As we drew near the river I perceived the huts of a tribe with a fire smoking before each. I immediately sent back for the gins, but before they could come up the natives whom we saw there noticed us and immediately disappeared among the reeds, shrieking as if they had been mad. Our females soon after approached their huts and called on them to return, but in vain. RIVERBANKS OF DIFFICULT ACCESS. BEST HORSE DROWNED. A misfortune befel us this evening which made the party better aware of the treacherous nature of the banks of this part of the Murrumbidgee. I had just time before it got dark to find a place where the cattle could approach the water, the banks being almost everywhere water-worn and perpendicular, and consequently inaccessible and dangerous to animals in descending to drink. To this point I had sent the sheep, and the men were leading the horses also towards it when the foremost, which unfortunately was the best, made a rush to the water at a steeper place, and fell into the river. He swam however to the other side but, in returning, sank in the middle of the stream, never to rise again. He had winkers on and I think it probable that he had put his foot into a short rein which was attached to the collar. This horse was of the Clydesdale breed and drew the cart containing my instruments throughout the journey along the Darling last year. His name was Farmer--an unfortunate appellation for surveying horses--for Farmer's Creek, in the new road to Bathurst, was named after another horse which fell there and broke his neck while I was marking out the line.
