f masses of
ironstone, granite, sand, and limestone, and in some places white marble.
Thinking that the creek we had passed might break through a low part of
the range, which I could see to the north-west, at ten miles I changed to
west, and crossed to the other range, but found the dip of the country to
the south. We could find no water; traced the creek to the south-east for
two miles, found some water and camped. The range is very rough and
stony, covered with spinifex; but the creeks are beautifully grassed.
Native smoke to east. This is one of the sources of Morphett Creek, and
flows to the east; it is as large, if not larger, than Attack Creek, and,
in all probability, contains water holes quite as fine to the eastward.
Latitude, 18 degrees 50 minutes 40 seconds.

Friday, 26th April, Morphett Creek. At 8 a.m. started on a course of 300
degrees to cross the north-west part of the range. Camped upon a plain of
the same description as John Plain, that I met with on my former journey
to the north-east of Bishop Creek, a large open plain covered with grass,
and with only a few bushes on it. The journey to-day has been very rough
and stony. Not a drop of water have we passed to-day, nor is there the
appearance of any on before us. I shall be compelled to fall back
to-morrow to the water of last night. Four of the horses, I am afraid,
will not be able to get there. I must try more to the north, and
endeavour to get quit of the plains, and get amongst the creeks. There is
no hope of success on this course. Latitude, 18 degrees 38 minutes. Wind,
east.

Saturday, 27th April, Grassy Plains. Started at 7.10 a.m., course 110
degrees, to the other side of the plain. At three miles came upon a small
creek running towards the north; I followed it down to the north. At
three miles came upon a fine large creek, coming from the south-east,
with plenty of water. Returned to the party, took them down to the large
creek on north course, and at three miles camped. Two of the horses are
nearly done up. Wind, south-east. Latitude, 18 degrees 35 minutes 20
seconds.

Sunday, 28th April, Tomkinson Creek. Sent Thring down to examine and see
how the creek runs. I have named it after S. Tomkinson, Esquire, Manager
of the Bank of Australasia, at Adelaide. We have found many new plants
and flowers, also some trees, one of which grows to a considerable size,
the largest being about a foot in diameter. The fruit is about the size
and colour, and
