Camp 40. We have been here now since the afternoon of Thursday last the 17th, and high time it is that we make some progress. Wind south-east; cold dewless nights; the meat has dried after a fashion but not sufficient for keeping any length of time without further exposure to sun and air--which we must do as soon as we get to camp for several days. Kirby has now quite recovered and we start on a bearing of 345 degrees. I call this small creek Black-eyes Creek--after the bullock we slaughtered here; at three and three-quarter miles crossed the what appears main channel of the creek coming from west-south-west, and various others coming in all directions; this is an immense creek, sandy and gravelly bed, with large and to me perfectly new trees, with short and broad dark green leaf and often clustering in fine saplings from the bottom and growing to a good height; also some fine gums. Creek now on the right; country after crossing the creek is splendidly grassed and firm sound ground between creek and range which is some distance off; but we will be gradually approaching it on our present course. At seven and a half miles crossed sandy creek from west; at ten one-eighth miles crossed large deep creek from west, at twelve miles sandy creek from west; and at fourteen miles sandy creek from west; at fourteen and a quarter miles large sandy creek, west, with water in sand; went down the creek east for a quarter of a mile to water and camped at the junction of the other creek we crossed a short distance back with this; the creek immediately below this is about 300 yards wide with excellent timber; there has been a little spinifex during today's travel but the bulk of it has been well-grassed and fresh varieties of good sound country; a specimen of copper picked up in one of the creeks; a great abundance of quartz and mica strewed everywhere. I think I forgot to mention that at the division of waters on the low bald undulations limestone is strewed about in large and small circular pieces from the size of a saucer to three and four feet in diameter, besides large blocks of it; the hills on the west are of a hard stone between flint and sandstone, strewed about with quartz; the eastern one is of burned slate or clay, pretty much resembling many that we have already passed and what I was on, topped with spinifex, and the side with good grasses.
