20TH JULY.--AFTER a little trouble with the gullies and brigalow scrub, on first setting off, we came upon fine undulating open forest land, and crossed many a gully and small water-course, all declining towards the N.E. A very remarkable flat-topped hill appeared on our right, resembling a wart, on one of these ridges; to the northward it was precipitous, and seemed to consist of a very red rock. At length, after crossing a ridge rather broader than the rest, with some brigalow scrub upon it, and one or two specimens of that tree of solitary places, the bottle tree, (DELABECHEA) we arrived at valleys and water-courses descending to the southward of west, into a valley turning to the N.W. One, at length, on our right, taking the direction in which I was proceeding, viz., 10 deg. W. of N., I followed it down, and thus entered a broader valley leading N.W. Following this, on a wide flat of open forest, we found at length a fine pond of water in it, and encamped beside it, after a journey of about twelve miles. This valley seemed to continue to the base of the lofty isolated mountain already mentioned, where a lower valley crossed it, falling either to the northward or southward. This I left in pleasing uncertainty until next morning, for I had remarked in that locality, when I stood on Mount Mudge, a long line of grey mist running north and south. I named the large mountain beyond that valley, Mount Beaufort, in honour of my scientific friend at the Admiralty. Thermometer, at sunrise, 40 deg.; at noon, 66 deg.; at 4 P.M., 73 deg.; at 9, 62 deg.. (LIII.)
