Wednesday, 28th July, Sand Hills. Started at 9 a.m. on a bearing of 283 degrees for two miles to examine the other lagoon, which is about three miles long, water salt. Changed our course to 182 degrees for ten miles to a large lake crossing our course. Changed our bearing to 240 degrees, and at four miles changed to 270 degrees, crossing some horse-tracks going towards the large lake. This seems to be a country of salt lagoons, for we passed three, and have seen a great many more. The large one that crossed our south course is evidently the head of Lake Gairdner. I could see it winding away in that direction. We have now got upon a plain slightly undulating with thick scrub and the unceasing mulga, intermixed with a few black oaks; no signs of water, no creeks. I intend to proceed north of west to intersect any creek or country that may come from the good country that we found on our south-east course, and the land of kangaroos; there is no hope of anything here. Camped without water. Distance to-day, twenty miles.
