September 19. — Travelling east through the same kind of country for fifteen miles, we halted upon a high scrubby ridge; having a few grassy openings at intervals, and with large sheets of granite exposed in some parts of its surface. In the holes among these rocks we procured a supply of water that had been deposited by the late rains; but which a few warm days would have dried up. The latitude of the water was 32 degrees 48 minutes S. and from it Mount Hall bore S. 38 degrees W., Mount Cooper S. 15 degrees W. Before us to the north-east were visible many peaks of a range, with a high and broken outline, which I named the Gawler range, after His Excellency Colonel Gawler, the Governor of South Australia. One very high peak in this range I named Mount Sturt, after my friend Captain Sturt; it bore from our present camp E. 10 degrees N. and had been previously seen from the summit of Mount Hall.
