"The reedy watercourse," is a chain of water-holes taking its rise among some grassy and picturesque ranges to the north of us, and trending southerly to a junction with the Broughton. Among the gorges of this range, (which I had previously named Campbell's range,)[Note 1: After R. Campbell, Esq. M. C. of Sydney.] are many springs of water, and the scenery is as picturesque as the district is fertile. Many of the hills are well rounded, very grassy, and moderately well timbered even to their summits. This is one of the prettiest and most desirable localities for either sheep or cattle, that I have yet seen in the unoccupied parts of South Australia, whilst the distance from Adelaide by land, does not at the most exceed one hundred and twenty miles. [Note 2: All this country, and for some distance to the north, is now occupied by stations.] The watercourse near our camp took its course through an open valley, between bare hills on which there was neither tree nor shrub for firewood and we were constantly obliged to go half a mile up a steep hill before we could obtain a few stunted bushes to cook with. As the watercourse approached the Broughton the country became much more abrupt and broken, and after its junction with that river, the stream wound through a succession of barren and precipitous hills, for about fifteen miles, at a general course of south-west; these hills were overrun almost everywhere with prickly grass and had patches of the Eucalyptus dumosa scattered over them at intervals. Up to the point where it left the hills, there were ponds of water in the bed of the Broughton, but upon leaving them the river changed its direction to the northward, passing through extensive plains and retaining a deep wide gravelly channel, but without surface water, the drainage being entirely underground, and the country around comparatively poor and valueless.

During the night the frost had been so severe, that we were obliged to wait a little this morning for the sun to thaw the tent and tarpaulins before they would bend to fold up. After starting, we proceeded across a high barren open country, for about three miles on a W. N. W. course, passing close under a peak connected with Campbell's range, which I named Spring Hill, from the circumstance of a fine spring of water being found about half way up it.
