threatened rain, but none fell: our stage
was 18 miles.

August 13.--Continuing our course to the N. W. I took on the cart for 13
miles to a large dry channel, coming from the hills, upon which we halted
for an hour or two to rest and feed the horses, as there were some
sprinklings of grass around. We had now a change in the appearance of the
country; the ironstone ranges seemed to decrease rapidly in elevation to
the north, and the region around appeared more level, with many very
singular looking table-topped elevations from 50 to 300 feet in height
and with steep precipitous sides which were red, with the ironstone
above, and white, with a substance like chalk, below. The country was
covered with salsolae, and we passed the beds of many dried up salt
lakes. Ascending the highest ridge near us, I found Lake Torrens was no
longer visible, being shut out by the sandy ridges to the westward,
whilst the low ironstone hills impeded our view to the north, and to the
east. Having given our horses water, we buried twelve gallons against our
return, and sending back the man with the cart, and extra horses, the
native boy and I still pushed on to the N. W., taking a pack-horse to
carry our provisions and a few quarts of water for ourselves.

As we proceeded, the country changed to extensive plains and undulations
of stones and gravel, washed perfectly level by water, and with the
stones as even in size and as regularly laid as if they had been picked
out and laid by a paviour. At intervals were interspersed many of the
fragments of table land I have alluded to before, only perhaps a little
less elevated than they had previously been; we passed also the beds of
several small dry watercourses, and encamped upon one of the largest,
long after dark, having travelled twenty-five miles since we left the
cart, and having made in the whole a day's journey of thirty-seven miles.
There was tolerable food in the bed of the watercourse, but the horses
were thirsty and eat but little. Unfortunately, in crossing the stony
ground, one of them cast a shoe, and began to go a little lame.

August 14.--Moving away very early we travelled sixteen miles due north,
through a very similar country, only that the stones and gravel in the
plains had become much finer and a good deal mixed with sand; the
fragments of table land still continued in every direction at intervals,
and their elevations still varied from 50 to 300 feet. In the upper part
