July 4.--Having mustered the horses this morning, I ordered an
arrangement to be entered into for taking them to the water twice a day,
and bringing down the supply required for the use of the party. Each
person undertook this duty in turn, and thus the labour was divided.
After breakfast I went up myself to examine the state of the water and
found great abundance in its bed; there were strong traces of recent and
high flooding, the drift timber being lodged among the bushes several
feet above the ordinary channel. The grass I was sorry to find was rather
old and dry, but still there was a very fair supply of it, a point of
great importance to us at a time when it was necessary to detain the
whole party for two or three weeks in depot, to enable me to examine the
country to the north; my former experience having convinced me that it
would be dangerous to attempt to push on, before ascertaining where grass
and water could be procured.

We had now travelled upwards of eighty miles under Flinders range, from
Crystal brook to Mount Arden, and hitherto the character of that range
had varied but little. High, rocky, and barren, it rises abruptly from
the plains, and so generally even is the country at its base, that we had
no difficulty in keeping our drays within a mile or two of it. This was
convenient, because we had not far to leave our line of route, when
compelled to send up among the ravines for water. The slopes of Flinders
range are steep and precipitous to the westward, and composed principally
of an argillaceous stone or grey quartz, very hard and ringing like metal
when struck with a hammer.

There was no vegetation upon these hills, excepting prickly grass, and
many were coated over so completely with loose stones that from the
steepness of the declivity it was unsafe, if not impossible to ascend
