summits of the hills passed over during the day had been seen from the Lyons River in 1858, and were now named the Capricorn Range. Camp 28. 24th June. A rather rough ride of four hours to the south-east brought us to a watercourse sixty yards wide, trending to the north-north-east, in which we found pools of water lined with reeds and flags. This was traced up to the southward till 3.0 p.m., when we entered a deep gorge in a sandstone range, the bed of the stream becoming very stony and full of melaleuca-trees; it, however, contained many fine pools and strong running springs, with a small supply of grass. There was now a fair prospect of our reaching the Lyons, as the range we were now entering must contain the sources of the Edmund, which river has a much more restricted course than was originally supposed. Camp 29. Latitude 23 degrees 42 minutes 15 seconds. 25th June. 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.
