at once into the gully, and followed it in all its windings; knowing well from experience that it is easier to find a passage up a mountain range than down it.  The gully had all the characters of those of the Boyd; the same sandstone rock, the same abruptness, and the same vegetation; excepting, perhaps, a new Grevillea, with pinnatifid leaves and yellowish-white woolly flowers, which we found here.  There was no water, except in some small holes full of gum leaves, which had rendered it unfit for use.  After proceeding with great difficulty about three miles, we found that the gullies opened into a broad flat valley; in which fields of fat-hen, the Croton shrub, the native Tobacco, Erythrina, fine specimens of flooded-gum, Tristania, and the Moreton Bay ash, were growing in great abundance.  Farther down, however, the Bricklow scrub covered the whole valley; the water-course disappeared almost entirely; and we were completely disappointed in our hopes of finding a fine country.  Small plains opened on both sides of the valley, surrounded by Bricklow scrub, and with patches of Bricklow scattered over them, in which the Bottle-tree frequently made its portly appearance.  A large flight of Wonga Wonga pigeons were feeding on the seeds of various species of Acacia; we shot two of them.  No water was to be found in an extent of fifteen miles.  The noisy call of the laughing Jackass (Dacclo gigantea) made me frequently ride back and examine more minutely those spots marked by a darker foliage; but the presence of this bird is no certain indication of water, though he likes the neighbourhood of shady creeks.  I could not help thinking that a considerable creek must come from the north-west side of Mount Nicholson; and, seeing an isolated range to the south-west, I rode towards it, sure of finding water near it, if there was any to be found.  We approached the range just before sunset, much tired, with two Wonga-Wongas and three iguanas at our saddles.  I had just informed my Blackfellow, that I wished to encamp, even without water, when some old broken sheets of bark, remains of the frail habitations of the natives, caught my eye; a dry water-hole, though surrounded with green grass and sedges, showed that they had formerly encamped there, with water.  This water-hole was found to be one of a chain of ponds extending along the edge of the scrub which covered the hill; and, on following it farther down, we came to a fine pool of water, which enabled us to encamp comfortably.  Next morning, after having enjoyed an iguana, and finding several other ponds well supplied with water, we returned.  In crossing several of the scrub plains before mentioned, it was agreeable to observe that the dense vegetation which covered them was not the miserable Burr and the wiry Vervain, but Senecios and Sonchus (Sowthistle), which our horses greedily snatched as they waded through them.  The soil is of a dark colour, very rich, but mild; and the rock below is basaltic.  Kangaroos were feeding
