“I very much regret not having been able to reach, at all events, within sight of Mount Lyell; but where I turned I could plainly see the whole country within fifty or sixty miles of the boundaries of the province, and can speak with almost as much confidence of its absolute sterility as if I had actually ridden over it.  It would certainly be possible in the wet season to take a small party from Prewitt’s Springs across to this hill of Sir Thomas Mitchell (distant about one hundred and sixty miles), by carrying on water for eight or ten days; but no further supply might be found short of the Darling (eighty miles beyond Mount Lyell), on which river it would be madness to attempt anything without a considerable force, on account of the natives; and the same point might be reached in nearly as short a time, and with much more certainty, with any number of men that might be considered necessary, by ascending the Murray as high as the Laidley Ponds, and proceeding north from thence.

“On returning to the depot, I moved the party down to Mount Bryan, and made another attempt on the 25th August, with Mr. Henderson, and one man leading a pack-horse, to the north-east, hoping, from the heavy rains which had fallen during the past two months, to find sufficient water in the ravines to enable me to push on for several days.  The second day, I crossed the high range I had observed from the Black Rock Hills and Mount Bryan, for the southern termination of which Colonel Gawler steered when he left the northern bend of the Murray in December, 1839; but though these hills had an elevation of twelve hundred or fourteen hundred feet above the plain, there was no indication of rain having fallen there since the deluge.  This want of water prevented my proceeding further to the north-east; but from the summit of the highest of these hills (Mount Porcupine,) I had a clear view of the horizon in every direction, and a more barren, sterile country, cannot be imagined.

“The direction of the dividing ridge between the basin of the Murray and the interior desert plain was generally about north-east from the Black Rock Hills (the highest point north of Mount Bryan,) gradually decreasing in elevation, and, if possible, increasing in barrenness.  The summits of those hills I found invariably rock—­generally sandstone—­the lower slopes covered with dense brush, and the valleys with low scrub, with occasional small patches of thin wiry grass.  I was obliged to return on the third day, and reached the foot of Mount Bryan on the fourth evening, at the southern extremity of which hill the horses were nearly bogged in the soft ground, though only fifty miles distant from land where the dust was flying as if in the midst of summer.

“It appears to me certain, from the result of these different attempts, that there is no country eastward of the high land extending north from Mount Bryan, as far as Mount Hopeless, a distance of about three hundred miles, as far as the meridian of 141 degrees (and probably much beyond it), available for either agricultural or pastoral purposes; and that, though there may be occasional spots of good land at the base of the main range on the sources of the numerous creeks flowing from thence towards the inland desert, these must be too limited in extent to be of any present value.
