The country continued hilly for about ten miles, when we arrived at the summit of a granite and sandstone tableland, at the extreme sources of the watercourse we had been following up.  From this point we had at last the satisfaction of observing the bold outlines of Mount Augustus, bearing south-south-east about thirty miles, while more to the westward could be discerned the summits of Mounts Phillips and Samuel, and yet more to the right the southern face of the Barlee Range.  Descending to the south across an open plain, we struck for a remarkable gorge in a granite range (the only one now between us and the Lyons), at which we arrived by sundown.  On examining this singular gorge, it was found to be an almost perpendicular cut through a narrow ridge nearly 300 feet in depth, the length of the pass not exceeding 200 yards, the plain on each side being nearly on the same level.  From the summit of this pass the course of the stream could be traced across the fertile flats of the Lyons until it was lost in the numerous channels of that river, and I was able to obtain bearings to many well-remembered objects noticed on my former visit to this part of the country.  Camp 30.

Latitude 23 degrees 56 minutes 45 seconds.

Return to depot.

26th June.

As we had only four days’ rations left, and no further object could be attained by advancing further south, unless there had been time to examine the present condition of the pasture in the vicinity of Mount Augustus, we marked several trees on the north side of the gorge close to a pool, and retraced our steps to within a mile of our camp of the 24th, having improved upon our outward track by keeping rather more to the eastward.  Camp 31.

27th June.

Instead of returning by the rough route by which we came through the Capricorn Range, we followed the stream to the north-north-east, through a good country all the way to the Ashburton, which river it joined in latitude 22 degrees 26 minutes, passing through the end of the range one mile south of the junction.  In this pass we encamped on a fine deep pool, in which we caught a small quantity of fish, showing the water to be permanent.  Camp 32.

28th June.

Making an early start, we soon crossed the Ashburton, and rode twelve miles across open plains, thinly timbered and yielding a large quantity of good pasture, principally of kangaroo-grass, which here grew to the height of six feet.  Resting for several hours at the waterholes of the 22nd, at 4.30 p.m. we resumed our route, having filled our water-kegs, and pushed on to within sixteen or seventeen miles of the depot, encamping amongst some good grass on our outward route, but without any water except what we carried with us.  Camp 33.

29th June.

Giving our horses rather more than a gallon of water each, we made an early start just as it came on to rain, which was the first shower we had experienced since the 27th May; it continued until noon, but not heavy enough to leave any surface-water on the parched and thirsty loam.  Keeping more to the westward than our outward track, we escaped much of the stony ground then passed over, and arrived at the depot camp by 2 p.m.
