September 23. — Moving on over a firm road, but with much scrub and prickly grass, we travelled for fifteen miles under the hills at a course of E. 20 degrees N., encamping early in the afternoon close under them, and procuring a little water left in the hollows by the rains. I ascended another of the heights in the Gawler range to-day, but could obtain no clear view from it, the weather being hazy. Ridge behind ridge still appeared to rise to the north, beyond the front one under which we were travelling; and several salt lakes were seen among the hills at intervals. The rock of which the hills were composed was now changed from a porphoritic granite to a reddish quartz, which was scattered all over the front hills in loose small fragments. The latitude of our camp was 32 degrees 30 minutes 35 seconds S.
