them severely. If the country does not become less stony, I
shall be compelled to leave some of them behind. We camped on a gum creek
about three miles to the west of the range. My only hope now of cutting
Cooper's Creek is on the other side of the range. The plain we crossed
to-day resembles those of the Cooper, also the grasses; if it is not
there, it must run to the north-west, and form the Glenelg of Captain
Grey. Distance to-day, twenty-one miles.

Saturday, 10th July, Gum Creek, West End of Large Stony Plain. Rested the
horses to-day. This evening we were surprised to hear a dog barking* at
the grey mare; its colour was black and tan. (* It is commonly supposed
that the native dingo or wild dog does not bark. This is an error. The
dog in this instance being black and tan, was probably a hybrid. (See
below.))

Sunday, 11th July, Same Place. This morning the sun rose at 62 degrees.
Bearing to-day, 272 degrees, so as to round the point of range, which
seems to have a little mallee in the gullies on this side, and some trees
on the west side. Started at 8.30 a.m., and at four miles ascended the
highest point of the range. The view to the north-east is over an immense
stony plain with broken hills in the distance. To the north is also the
plain, with table-hills in the far distance. To the north-west is the
termination of the range running north-east and south-west, distant about
ten miles; about half-way between is a gum creek running to north-east.
To the west is the same range, and a number of conical hills between.
Changed our bearing to 220 degrees in order to break through the range.
This range is very stony, composed of a hard milky-white flint stone, and
white and yellow chalky substance, with a gradual descent on the other
side to the south, which is the finest salt-bush country that I have
seen, with a great quantity of grass upon it. The grey mare has been very
bad; her belly was very much swollen, but this morning she seemed better.
Towards afternoon, however, she fagged very much, which caused me to stop
so soon. I am almost afraid that I shall lose her. I shall see how she is
in the morning, and, if she is no better, I will endeavour to get her on
to some permanent water or creek running to the south. I think we have
now made the dip of the country to the south, but the mirage is so
powerful that little bushes appear like great gum-trees, which makes it
very difficult to judge what is before us; it is alm
