Wednesday, 6th June, Gum Creek, North-east Side of the McDouall Ranges. There being nothing but spinifex on the ranges and creeks, the horses had been travelling nearly all night in search of food, and had gone a long way before they were overtaken. This morning saddled and got a start by 11 o'clock on a course of 340 degrees, crossing numerous creeks and stout spinifex, through which we had great difficulty in driving the horses. At five miles struck a gum creek in which we found water. The banks have excellent feed upon them, and in abundance, so, for the sake of the horses, I have determined to remain here to-day. This creek, which I have named Tennant Creek, after John Tennant, Esquire, of Port Lincoln, runs east. In searching for the horses this morning Ben found three or four more large water holes in the adjoining creek, a little south-east from this. Before we reached this, we crossed some marks very much resembling old horse-tracks. Thursday, 7th June, Tennant Creek, McDouall Ranges. Started at 7.20. Course, 340 degrees. At three miles passed through an immense number of huge granite rocks piled together and scattered about in every direction, with a few small water-courses running amongst them to the eastward. We then encountered a rather thick scrub, and occasionally crossed a few low quartz rises coming from the McDouall ranges. At fourteen miles ascended the highest of them, which I have named Mount Woodcock, after the Venerable the Archdeacon of Adelaide. To the north-west and north is another range, about ten miles distant, which seems to continue a long way. I will change my course to 315 degrees, which will take me to the highest point. At two miles on this course came upon a gum creek running to the north-east, which I named Bishop Creek; followed it for one mile and a half, and found water, which will last a month or six weeks, and an immense number of birds. This is a camping-place of the natives, who seem to have been here very lately. We watered the horses and proceeded towards the range. At about two miles passed a low rugged ironstone range, peculiar in having a large square mass of ironstone standing by itself about the centre. I have named it Mount Sinclair, after James Sinclair, of Port Lincoln. Passed through a thick scrub, among which we saw a very handsome bush that was new to us, having a blue-green leaf ten inches long by six inches broad. We looked for some seed, but could not find any. At five miles crossed a grassy gum plain, where a creek empties itself. The same scrub continues to the range, which we reached at twelve miles from the water. It is not very high, but rough and steep, and we had great difficulty in getting to the top, but after many twistings and turnings and scramblings, we arrived there all right, and found it to be table land. At fourteen miles camped without water. The range is composed of ironstone, granite, quartz and red sandstone, running north of west and south of east.
