covered with brushwood and cypress with a few grassy patches; at 11.10
passed a native well; altered the course to west-south-west, crossing
three small watercourses trending north-west; and at 1.15 p.m. halted at
the foot of a bare granite hill, on the top of which there was a fine
pool of rainwater in a shallow basin of the rock.

Latitude 28 degrees 50 minutes 51 seconds; longitude 116 degrees 29
minutes.

7th September.

Started at 7.15 a.m. on a course 255 degrees through acacia thickets; at
10.5 crossed a narrow strip of salt marsh, which spread out into dry salt
lakes to the south; after this the country was grassy till 11.30, when we
entered a dense thicket of acacia, melaleuca, cypress, and eucalypti, the
ground gradually rising till 4.0 p.m., and then descending till 5.25,
when we crossed a small dry watercourse trending south; at 6.10

Latitude 28 degrees 58 minutes 14 seconds; longitude 116 degrees 6
minutes.

8th September.

Leaving the bivouac at 7.0 am steered west; at 7.20 came to a grassy
granite hill, then west-north-west to another hill, where we halted for

westerly course through acacia thickets, alternating with grassy gum
