Thursday, April 5th, Good Country. Started on the same course to some hills, through sand hills and spinifex for ten miles. Halted for half an hour to obtain an observation of the sun, 117 degrees 6 minutes. Within the last mile or two we have passed a few patches of shea-oak, growing large, having a very rough and thick bark, nearly black. They have a dismal appearance. The spinifex now ceased, and grass began to take its place as we approached the hills. From the top of the hill the view is limited, except to the south-west, where, in the far distance, is a long range. The country between seems to be scrub, red sand hills, and spinifex. To the west the country is open, but at five miles is intercepted by the point of the range that I am about to cross. To the north-west and east is a mass of flat-topped hills, of every size and shape, running always to the east. Camped on the head of a small gum creek, among the hills, which are composed of the same description of stones as the others. This water hole is three feet deep, and will last a month or so. The native cucumber is growing here.
