With this occurred another species with hard stiff scymetar-shaped leaves
and a profusion of balls of browner yellow flowers which had been
previously observed (on June 22) in a more vigorous condition.* By
observations from this hill I made the height of Mount William about
4,500 feet above the sea.

September 20.

Our wheels now rolled lightly over fine grassy downs and our faces were
turned towards distant home. Before us arose a low, thinly-wooded hill,
which at first bounded our view towards the north, and afterwards proved
to be the feature connecting the low woody ridge near our last camp with
the hills still further to the northward. On reaching the summit I
perceived that a considerable extent of open country intervened, being
watered in the lower parts by several lakes.

MOUNT NICHOLSON. COCKAJEMMY SALT LAKES.

Descending northward along an offset of the same hills which had led us
in that direction and which I now named Mount Nicholson, I observed that
the lakes occurred at intervals in a valley apparently falling from the
westward in which no stream appeared, although it was shut in by well
escarped rocky banks. We encamped after a journey of ten miles at a point
where another valley from the north joined the above, and I was somewhat
surprised to find after encamping that the water in the adjacent lakes
was extremely salt. No connection existed by means of any channel between
them although they formed together a chain of lagoons in the bed of a
deep and well defined valley. On the contrary the soil was particularly
solid and firm between them, and the margin of the most eastern of these
lakes was separated by a high bank from the bed of another valley where a
running stream of pure water flowed over a broad and swampy bed fifteen
feet higher than the adjacent valley containing the stagnant salt lakes.
The rock enclosing these singular valleys was basalt, and from these
peculiarities, considered with reference to the ancient volcano and the
dip of a mountain strata to the north-west, i
