Sunday, 15th April, The North Gorge of McDonnell Range. I ascended the high hill on the east side of the gorge; the atmosphere being much clearer, I got a better view of the country. To the north-west, between the McDonnell range and the conical hill north-north-west, is a large plain, apparently scrub; no hills on the horizon, but a light shade in the far distance; the conical hill bears 340 degrees from this; it appears to be high. From the foot of this, for about five miles, is an open grassy country, with a few small patches of bushes. A number of gum creeks come from the ranges, and seem to empty themselves in the plains. The country in the ranges is as fine a pastoral hill-country as a man would wish to possess; grass to the top of the hills, and abundance of water through the whole of the ranges. I forgot to mention that the nut we found on the south side of the range is not fit to eat; it caused both men to vomit violently. I ate one, but it had no bad effect on me. Monday, 16th April, The North Gorge of McDonnell Range. Started at 9 o'clock to cross the scrub for the distant high peak. For five miles the plain was open and well grassed: afterwards it became thick, with mulga bushes and other scrubs. At twenty miles we again encountered the spinifex, which continued until we camped after dark. Distance, thirty miles. Met with no creek or watercourse after leaving the McDonnell ranges. Tuesday, 17th April, In the Scrub. Got an early start, and continued through the scrub and spinifex on the same course, 340 degrees. At three miles passed a small stony hill, about two miles to the west of our course. At eighteen miles saw to the west two prominent bluff hills, and two or three small ones, about ten miles distant from us. At thirty-two miles crossed a strong rise. There are three reap-hook hills about three miles west, their steep side facing the south. At sundown reached the hills. At two miles passed a small sandy gum creek, the only watercourse we have seen between the two ranges. Followed the range to the north-west till after dark, hoping to find a gum creek coming from the range, but without success; nothing but rocky and sandy watercourses. Camped. The poor horses again without water; I trust that I shall find some for them in the morning; if not, I shall have to return to the McDonnell range. Very little rain seems to have fallen here; the grass is all dried up. The spinifex continues until within a mile of the range. The small gum creek that we passed is running south-west into the scrub.
