LAKE AUGUSTA. 23rd. Steering south for about eight miles, we reached the lake, which I named Lake Augusta. The water is salt, and about five miles in circumference. Grassy country in the flat; red sand-hills along the shore. It appeared deep, and swarmed with ducks and swans. Pierre shot two ducks, after which we pushed on North-East for about twelve miles to a low rocky bluff, which we ascended and got a view of the country ahead--rough broken ranges to the east and south. We continued on east for six miles, when, on approaching a rocky face of a range, we saw some natives on top of it, watching us. Approaching nearer, we heard them haranguing and shouting, and soon afterward came within thirty yards of one who was stooping down, looking intently and amazedly at us. I made friendly signs, but he ran off shouting, and apparently much afraid. He and several others ran up and joined the natives on the cliff summit, and then all made off. We turned, and steering East-North-East for six miles, and then east for about fourteen miles, the last few miles being miserable spinifex country, we camped, with poor feed, amongst some spinifex ranges. A good deal of grassy country the first part of the day. Kangaroos very numerous, and emus also. Evidences of the natives being in great numbers. 24th. Ascended a red-topped peak close to our bivouac and got a view ahead. A salt lake was visible a few miles to the east, towards which we proceeded. Passing along samphire flats and over red sand-hills, we got within a mile of the lake. The country close to it not looking promising, I determined to turn our faces westward towards the party. Steering a little south of west for three miles, we struck a large brook trending North-East into the lake, and, following it up a mile, found a fine pool of fresh water, with splendid feed. This is very fortunate, as it is a good place to bring the party to. Elated with our success, we continued on westerly, passing some fine rock water-holes, half full of water, and at twenty miles from the pool we found a springy hole, with plenty of water in it, within a few hundred yards of our outward track. We had missed it going out; it is in the centre of a very fine grassy plain. Kangaroos and emus numerous, also natives. Giving the horses water, we pushed on for twelve miles and camped on some fine grassy flats. Every appearance of rain. ANOTHER NATIVE.
