Tuesday, 10th August, Rock Water. Started at 8.30 on a bearing of 180 degrees. Camped at eighteen miles without water, and a very little food for the horses, only a little salt bush. The appearance of a change from the dreary desert lasted only for about one mile from where we camped last night; it then became even worse than before--the sand hills higher, steeper and closer together, the spinifex thicker and higher; we got the horses through it with difficulty. It rained all last night and all day. There is some rising ground to the west. Distance to-day, eighteen miles.
