August 22.—Setting off early this morning, accompanied by a native boy, I steered W.N.W. For the first four miles, I took my overseer along with me, to shew him the direction I intended to take, so that if I did not return in two days, he might send a pack–horse with water to meet me along the tracks.
After he had left I pushed steadily on for thirty–five miles, principally over heavy sandy ridges, which were very fatiguing to the horses, and at dark reached the outer dunes of the lake, where I was obliged to tie the horses up to some small bushes, as there was neither water nor grass for them. The bed of the lake where I struck it, seemed dry for some distance from the shore, but towards the middle there appeared to be a large body of water. From our camp Mount Deception bore E. 26 degrees S. and Termination Hill, E. 35 degrees N.
