26TH JUNE. The party moved forward, at length, with the certainty of finding water for at least three days' journey, and of a hopeful water- course being before us. Passing by the foot of Mount Owen, I observed the barometer which gave an elevation of 2083 feet: the summit might be 700 feet higher. My plan of route was, to enter the little river that turned to the south-west (as I had found it did, on the 20th,) and to travel along its valley upwards, until I reached the pond near which I had bivouacked on the 25th. This we accomplished most successfully before sunset, encamping beside the large pond already mentioned, near which were two others. The earth by the margin was so soft that neither the horses nor bullocks could approach the water; they could only be watered out of buckets; but the water was excellent, and water of any quality, in abundance too, was to us rather uncommon good fortune, and quite cheering, even when surrounded by soft mud. Thermometer, at sunrise, 14 deg.; at noon, 48 deg.; at 4 P. M. 47 deg.; at 9, 37 deg.. 27TH JUNE. We had next to trace up a grassy valley which seemed to come directly from the vicinity of that in which I had found water and bivouacked on the 24th. It formed an excellent line, and we found it possible to keep this fine firm level surface, until we had approached to within two miles of that spot. Leaving a little hill of trap to the left, and some brigalow scrub on the right, we reached the old ground and encamped. The small ponds had evaporated, but, in the frosty night, the cattle were not likely to require water, as they had been watered on the way, about 3 P. M., at a rocky well in the valley. We had now traced with our wheels, a good way through a country much broken and shut up by sandstone gullies; but which contained also many rich valleys, and extensive hilly tracts of trap rock, on which the grass was very luxuriant, apparently available for either sheep or cattle. Immediately to the westward of this camp (marked XXXVIII.) an extensive valley was bounded by the fine trap range of Hope's Table Land; which range was open along the summit, and contained springs, in various ravines along its sides. In these ravines, we first saw the arborescent Zamia, and various remarkable shrubs; the MYOPORUM CUNNINGHAMII of Swan River, forming a shrub six feet high, with white fragrant flowers. Thermometer, at sunrise, 20 deg.; at 9 P. M., 29 deg.. Height above the sea, 2064 feet.
