Crossing an open forest hill, which had hitherto bounded our view to the westward, I perceived a deep grassy valley on our right, sloping towards a much lower country, but I still travelled westward, in hopes to find an open country, beyond a low woody range on which we had at length arrived. I soon, however, perceived rocky gullies before me, and having halted the party to examine them, I found they were quite impassable. Such an unexpected obstacle, on the horizon of the fine open country, yet UNDER that smooth horizon, was certainly as singular as it was unexpected, and I returned to descend into the deep grassy valley I had seen on our right, which seemed open and inviting. We therein also found some large ponds of water, and encamped. While the men were pitching the tents I rode down the valley about two miles, and found that the direction of the water-course was about north-east. Such a direction was not very favourable for us, and I resolved to look at the country beyond the limits of this valley to the westward, before we followed it further. Latitude, 24° 17' 42" S. Thermometer, at sunrise, 19°; at 4 P. M., 66°; at 9, 49°. (L.) 1279 feet above the sea.
15TH JULY.--Following up a flat which came from the N. W., I proceeded about five miles amid overhanging precipices, until, at length, mighty rocks rendered it quite impossible to push my horse further. Leaving him in a hollow, I ascended a rocky point, which was barely accessible with Yuranigh's assistance, and, on reaching an elevated summit, I saw still worse gullies before us, amongst which I could perceive no feature affording any cue to their final outlet, nor any characteristic of the structure of these labyrinths. I looked in vain for the rugged summits I had seen peeping over the plains when first discovered, and could not then be convinced (as I found long afterwards, on completing my map), that they were then under my feet. The highest parts seemed to extend south-westward. To cross such a region with our carts, was quite impossible, and I could only return, and, however reluctantly, follow down the valley in which we had encamped, until it should afford access to a more open country. The banks of the watercourse were steep, the bottom was sandy. The course was very tortuous, alternately closing on rocky precipices, at each side of the valley. Thus we were obliged to cross at every turning, and the steep banks rendered each crossing a difficult operation, occasioning so much delay, that after crossing ten times, evening obliged us to encamp, although our direct distance from the last camp did not exceed five miles. We had, at each crossing, cut the banks, filled up hollows with logs, etc. The general direction, I ascertained to be N.E. Water was found providentially near the spot, where the approach of night had obliged us to encamp; this having been the first water we had seen during that day's laborious journey. Thermometer, at sunrise, 21°; at 4 P.M., 65°; at 9, 44°.
