in a south-westerly direction, passing some low ridges.  We reached the higher ones in twenty-two miles.  Nearing them, we passed over some fine cotton-bush flats, so-called from bearing a small cotton-like pod, and immediately at the hills we camped on a piece of plain, very beautifully grassed, and at times liable to inundation.  It was late when we arrived; no water could be found; but the day was cool, and the night promised to be so too; and as I felt sure I should get water in these hills in the morning, I was not very anxious on account of the horses.  These hills are similar to those lately described, being greatly impregnated with iron and having vast upheavals of iron-coated granite, broken and lying in masses of black and pointed rock, upon all their summits.  Their sides sloped somewhat abruptly, they were all highly magnetic, and had the appearance of frowning, rough-faced, bastion walls.  Very early I climbed up the hills, and from the top I saw the place that was afterwards to be our refuge, though it was a dangerous one.  This is called the Cavanagh Range, but as, in speaking of it as my depot, it was called Fort Mueller*, I shall always refer to it by that name.  What I saw was a strong running stream in a confined rocky, scrubby glen, and smokes from natives’ fires.  When bringing the horses, we had to go over less difficult ground than I had climbed, and on the road we found another stream in another valley, watered the horses, and did not then go to my first find.  There was fine open, grassy country all round this range; we followed the creek down from the hills to it.  On reaching the lower grassy ground, we saw Mr. Gosse’s dray-track again, and I was not surprised to see that the wagon had returned upon its outgoing track, and the party were now returning eastwards to South Australia.  I had for some days anticipated meeting him; but now he was going east, and I west, I did not follow back after him.  Shortly afterwards, rounding the spurs of these hills, we came to the channel of the Fort Mueller creek, which I had found this morning, and though there was no surface-water, we easily obtained some by digging in the sandy creek-bed.  A peculiarity of the whole of this region is, that water cannot exist far from the rocky foundations of the hills; the instant the valleys open and any soil appears, down sinks the water, though a fine stream may be running only a few yards above.  Blankets were again required for the last two nights.  I found my position here to be in latitude 26 degrees 12’, longitude 127 degrees 59’ 0”.

Leaving this encampment, we struck away for a new line of ranges.  The country was very peculiar, and different from any we had yet met; it was open, covered with tall triodia, and consisted almost entirely of limestone.  At intervals, eucalyptus-trees of the mallee kind, and a few of the pretty-looking bloodwood-trees and some native poplars were seen; there was no grass for several miles, and we only found
