the dividing range between eastern and western
waters. Our Pass seemed to be the only outlet through the labyrinths
behind us. Even the open plains beyond them were visible in a yellow
streak above the precipices. Far beyond these plains, Mount Faraday was
distinctly visible, on the horizon of the landscape. Thermometer, at
sunrise, 29 deg.; at 9 P.M., 43 deg.. (LI.) 1234 feet above the sea.

18TH JULY.--By retracing our horses' footsteps, the carts were soon
brought to the base of the same hill; deep gullies in the clay having
obliged us to pass close under it, and, indeed, to cross two of its
elevated extremities. We found the country beyond, in a N.W. direction,
tolerably open, and we encamped in a valley containing abundance of
grass, and near to our camp, water was found in a chain of ponds
descending to the eastward. A new SUAEDA, with short leaves, and the
habit of a dwarf Tamarisk, was found this day.[*] Latitude, 24 deg. 6' 47" S.
Thermometer, at sunrise, 31 deg.; at noon, 65 deg.; at 4 P.M., 69 deg.; at 9, 44 deg..

cylindraceis imbricatis obtusissimis, axillis lanatis, floribus
solitariis sessilibus.]

19TH JULY.--With the intention to lose no opportunity of getting further
to the westward, I travelled on towards the base of the most northern
summit of the range in the west; but I was, at length, so shut up by
gullies and scrubby extremities near its base and all radiating from it,
and becoming very deep, that I took the party aside into a grassy ravine
near, where I directed the men to encamp, and hastened myself to the
summit. From it, the view westward was not so extensive as I expected.
Something like precipitous slopes to some channel or water-course,
apparently falling either S. W. or N. E., formed the most promising
feature; but, although my object was to have travelled in that direction,
the scrub seemed too thick to admit of a passage. Open forest land
appeared to the N. E., and there, the gently undulating features,
although much lower than the range on whose northern extremity I then
stood, seemed nevertheless to form a connection between it and some
higher ranges of open forest land, that appeared between me and the
coast. Through one wide opening in these, about east, I saw some broken
hills, at a very great distance, say seventy or eighty miles. The ridgy-
connected undulations formed the heads of some valleys slop
