horses, and then proceeded 40 degrees till 2.20
p.m., when we arrived at the foot of the highest hill in the range for
which we had been steering. Leaving our horses, we ascended the hill,
which was composed of trap-rock, and did not exceed 300 feet in height
above the general level of the country. From the summit several similar
ranges of trap hills were visible, extending from north to
east-south-east; to the south-east the country appeared to be a level
sandy desert without the least appearance of vegetation, while to the
west and north the smokes of many native fires were visible in the
distance. The extremely level character of the country between the ranges
to the east and north, and the immense columns of red sand or dust which
were raised by whirlwinds to a height of 200 to 500 feet, gave but little
hope of finding water in that direction. Returning to our horses at 4.20,
steered 350 degrees about three and a half miles to a small patch of
grass which had been observed from the hill, which was named Mount
Jackson. There was a small watercourse through the patch of grass, but no
water, and the country was suffering from prolonged drought.
Latitude by observation 30 degrees 12 minutes 28 seconds; longitude 119
degrees 16 minutes.
18th August.
After six hours' ineffectual search for water, we were compelled to
return to the water passed early on the previous day.
19th August.
Left the bivouac at 7.20 a.m. and steered 275 degrees through a scattered
gum forest with much underwood; at 9.55 came on a dry salt lagoon of
irregular form, which was crossed at 10.20; passing a native well among
flat granite rocks, the country rose gradually till 11.50, when we
arrived at a hill crowned by steep white sandstone cliffs twenty to
thirty feet high. The course was then changed to north, through dense
thickets, till 12.20 p.m., when we again turned west through a
well-wooded country, and at 3.0 camped on a high granite hill with some
patches of grass and abundance of rainwater in the hollows of the rocks.
Latitude 30 degrees 19 minutes 33 seconds; longitude 118 degrees 55
minutes.
20th August.
At 7.30 a.m. resumed a westerly course through dense thickets of acacia
and melaleuca, and at 5.15 p.m. bivouacked in a small patch of grass and
a small pool of rainwater on a granite rock.
Latitude 30 degrees 17 minutes 40 seconds; longitude 118 degrees 35
minutes.
21st August.
At 7.45 a.m. started on a course 3
