th much
prickly grass growing upon it.

Upwards, the Rocky river, after emerging from the gorges in which we
found it, descended through very extensive plains from the
north-north-east; there was plenty of water in its bed, and abundance of
grass over the plains, so that in its upper parts it offers fine and
extensive runs for either cattle or sheep, and will, I have no doubt, ere
many years be past, be fully occupied for pastoral purposes.

From our present encampment a very high and pointed hill was visible far
to the N.N. W. this from the lofty way in which it towered above the
surrounding hills, I named Mount Remarkable. Our latitude at noon was 33
degrees 25 minutes 26 seconds S.

A very beautiful shrub was found this afternoon upon the Rocky river, in
full flower: it was a tall slender stalked bush, about six or eight feet
high, growing almost in the bed of the river, with leaves like a
geranium, and fine delicate lilac flowers about an inch and a half in
diameter; here, too, we found the first gum-trees seen upon any of the
watercourses for many miles, as all those we had recently crossed,
traversed open plains which were quite without either trees or shrubs of
any kind.

June 28.--This morning we passed through a country of an inferior
description, making a short stage to a watercourse, named by me the
"Crystal Brook;" it was a pretty stream emanating from the hills to the
north-east, and marked in its whole course through the plains to the
northward and westward by lines of gum-trees. The pure bright water ran
over a bed of clear pebbles, with a stream nine feet wide, rippling and
murmuring like the rivulets of England--a circumstance so unusual in the
character of Australian watercourses, that it interested and pleased the
whole party far more than a larger river would have done; this
characteristic did not, however, long continue, for like all the streams
we had lately crossed, the water ceased to flow a short distance beyond
our crossing place.

The country below us, like that through which the Rocky river took its
course, was open and of an inferior description, but I have no doubt that
by tracing the stream upwards, towards its source among the ranges, a
good and well watered country would be found; I ascertained the latitude
by a meridian altitude at Crystal brook to be 33 degrees 18 minutes 7
seconds S.

The hills on the opposite side of Spencer's Gulf were now plainly
visible, and one which appe
