m of its gullies--keeping to the right along the main
range for about three miles, we came to the spur on which I and Charley
had ascended on our return, and which had a general direction to the
north-west. When we arrived at the foot of the range, our cattle and
horses were so jaded, and the water-hole still so far off, that I
encamped here, more especially as the feed was young and rich, and as I
had hopes of obtaining water by digging into the sand which filled the
upper part of the valley. In this, however, I did not succeed; for, upon
digging about three feet deep, I came on a layer of stiff clay very hard
and dry. Fortunately, however, a thunder-storm came on towards the
evening, which supplied our cattle as well as ourselves with water. This
was the only time we encamped without a certainty of water, during our
journey from Jimba to the head of the gulf, which occupied ten months.
The whole night was showery, the wind and clouds coming from all
directions.
Dec. 14.--We reached the water-holes I had discovered three days
previous. Our cattle were very thirsty, notwithstanding the late rain,
and they rushed into the water as soon as they got sight of it.
The hills, at the foot of which we are encamped, are composed of
whinstone (basalt). Pebbles of conglomerate, of flint, and of quartz
deeply coloured with iron, are, however, very frequent on the slopes. It
is remarkable that that part of the range which is composed of basalt, is
a fine open forest, whereas the basaltic hills of the large valley are
covered with dense scrub. The Myal was frequent; and the fruit of the
small lemon-tree was ripe.
I followed the watercourse which connects the water-holes on which we
encamped, and met every where with Bricklow scrub. Mr. Gilbert ascended
the hills, and stated that the whole valley to the westward appeared like
an immense sea of scrub.
A thunder-storm was forming to the north-west, but was probably deflected
by the ranges.
Dec. 15.--Last night we had two thunder-storms; one rose in the west, and
turned to the northward, following the Christmas Ranges; the other rose
in the south, and turned to the east, probably attracted by Expedition
Range. Still following the watercourse, we entered, after about four
miles travelling, into the scrub. The watercourse was soon lost in the
level ground, and water-holes appeared every where; the general direction
of the waters seemed to be to the north-west. Four miles farther
