September 21. — We had another long stage to-day of twenty miles, over, if possible, a worse road than yesterday, no intermission whatever of the heavy steep sandy ridges and dense eucalyptus scrub; the horses were dreadfully jaded, and we were obliged to relieve them by yoking up all the riding horses that would draw. Even with this aid we did not get the journey over until an hour and a half after dark. During the day our course had been more to the northward of east, and brought us close under the Gawler range. At fourteen miles after starting, we passed a salt lake on our right, and several salt ponds on our left; but we could find no permanent fresh water anywhere. In the rocks of the range we had encamped under, we procured a small quantity left by the rains, but this supply was rapidly disappearing under the rays of a very hot sun, and had we been a few days later, we could not have crossed at all. The latitude of our camp was 32 degrees 41 minutes 40 seconds S.
