16th September.

As there was no grass for the horses, we were compelled to push on our
journey, and at 7.20 a.m. steered 160 degrees; the country was more
broken up by valleys, the soil sand and ironstone, with heathy scrub,
banksia, and grass trees (xanthorrhoea) with a few patches of white-gum
forest; at 10.30 steered 138 degrees towards a high summit, distant
twelve miles. The horse again knocked up, but by relieving him of his
load, which was transferred to the other horses, succeeded in driving him
a few miles further. At 2.20 p.m. changed the course to 180 degrees, and
entered a level sandy piece of country, bounded on all sides by hills; at
3.40 altered the course to south-west; at 5.0 had to abandon the weak
horse and continue our route in search of water; at 5.30 passed a small
salt lake with a little grass on the margin; at 6.0, finding the country
getting worse, returned to the salt lake and camped on the western side.

Latitude 30 degrees 27 minutes 19 seconds; longitude 115 degrees 47
minutes.

17th September.

After digging in about twenty different places around the lake, at length
found fresh water, and then went back for the knocked-up horse, and with
some difficulty got him to the well, where we decided to rest the horses
this and the following day, before encountering the inhospitable sandy
region to the southwards.

18th September.

One of the party made a short excursion to the west of the plain, and in
about three miles reached the hills, which appeared very barren and
scrubby; but after crossing the first ridge, the country was timbered
with York and red gum and a large species of acacia, producing abundance
of gum; the soil a red loam, producing some grass and abundance of the
everlasting flowers and warran, or native yam. After penetrating this
good country four miles returned to the camp, having shot a kangaroo and
ten cockatoos.

19th September.

Leaving the camp at 8.5 a.m., steered 160 degrees, and soon ascended the
sandy downs, which were destitute of trees, except a few banksia and
floribunda; at 11.45 crossed a valley trending to the west; at 1.15 p.m.
observed a range of wooded hills to the east and south; altered the
course towards a remarkable gorge which bore 129 degrees; at 3.30 entered
a gum forest, and at 3.50 came to a large stream-bed with many pools of
water; followed it down south, and camped at 4.20.
