traversing open plains of great extent, and very stony. In some of these
plains we found large puddles of water much discoloured by the soil, so
that it was evident there had been heavy rains in this direction, though
we had none to the southward.

After travelling twenty-four miles we came to a large watercourse winding
from Flinders range through the plains, with its direction distinctly
marked out by the numerous gum-trees upon its banks. This was the "salt
watercourse" of my former journeys so called from the large reaches of
salt water in its bed a mile or two among the hills. By digging in the
gravelly bed of the channel, where the natives had scooped a small hole,
we got some tolerable water, and were enabled to give as much as they
required to our horses, but it was a slow and tedious operation. We could
get very little out at once, and had to give it to them to drink in the
black boy's duck frock, which answered the purpose of a bucket amazingly
well.

There was not a blade of grass, or anything that the horses could eat
near this creek, so I was obliged to tie them up for the night, after
giving to each a feed of oats.

July 7.--Towards morning several showers of rain fell, and I found that I
had got a severe attack of rheumatism, which proved both troublesome and
painful. Pushing on for ten miles we reached the height standing out from
the main range which Colonel Gawler named Mount Eyre, from its having
been the limit of my first journey to the north in May 1839. This little
hill is somewhat detached, of considerable elevation, and with a bold
rocky overhanging summit to the southward. Having clambered to the top of
it, I had an extensive view, and took several bearings.
