olour.
Being deeply cracked by vertical fissures, it forms vertical columns of
rhomboidal form, resembling basalt. The summits of the higher hills are
formed by horizontal beds of white sandstone, containing water-worn
pebbles of quartz. Granite supersedes the other rocks as the east slope
of the range is approached, and is there occasionally intercepted by
veins of dark trap.

9th October.

Proposed to start from the camp at the usual time, but four of the horses
could not be found, and owing to the rocky nature of the country the
tracks were not found till late in the evening, when tracing them some
miles I found them at sunset in a secluded valley.

10th October.

This morning we were more successful in collecting the horses, and
started from the camp at 6.35 a.m., and steering an easterly course
reached the fate of the range at 10.20 and the summit at noon. Following
our previous track, reached the pool of water at 1.0 p.m. and camped.
Near the camp the xanthorrhoea first made its appearance.

CROSS THE MAIN DIVIDING RANGE.

11th October.

Leaving the camp at 7.0 a.m., steered an easterly course over somewhat
barren granite country, timbered with cypress and ironbark; passed close
to a hill on the highest point of the range, the summit of which, by
approximate measurement, rose to 2500 feet above the sea. Then following
a spur of the range we reached the well in the sandy creek at 1.5 p.m.
Having cleared out the sand and banked it up with stakes and brushwood, a
plentiful supply of water was obtained at about five feet below the
surface of the dry channel.

Latitude by e Pegasi 18 degrees 45 minutes 53 seconds.

12th October.

At 7.0 a.m. steered north 60 degrees east over undulating granite
country, timbered with ironbark and box, the grass scanty and very dry;
at 8.45 crossed a large creek coming from the south. Its channel was 100
yards wide, dry, sandy, and a few pools of shallow water; the banks ten
to twenty feet high. Crossing several gullies trending northward, at noon
came on a dry sandy creek, also trending to the north. On its right bank
was a level flat of cellular lava or basalt. Following the course of the
creek, at 1.50 p.m. camped at a fine lagoon a quarter of a mile long and
seventy yards wide, the water appearing to be about ten feet deep,
although unusually low at the present time. A high range of hills exist
to the north of this creek, and the watercourses all trend to the
north-wes
