 Brisbane River. Encamping, I ascended a remarkable square-topped mount, which formed the western termination of one of these ridges; and from its summit had a very extensive view of the country lying between north and south, towards the west. At N. and N.N.W. we observed a succession of heavily-timbered ridges, extending laterally from the more elevated chain of mountains immediately to the east, which evidently forms the main dividing range in this part of the country; whilst from north-west to west, and thence to south, within a range of twenty miles, a most beautifully diversified landscape, made up of hill and dale, woodland, and plain, appeared before us.

Large patches of land, perfectly clear of trees, lying to the north of Darling Downs, were named Peel's Plains, whilst others, bearing to the south and south-east, and which presented an undulated surface with a few scattered trees, were called after the late Mr. Canning. Directing our view beyond Peel's Plains to the northwest, an expanse of flat, wooded country met the eye, being evidently a continuation of those vast levels, which we had frequently observed, in the progress of our journey, extending to the westward of our line of route, and which, it was now perceived, were continued northerly at least to the parallel of 27°.

In a valley which led to the immediate base of the mountain-barrier, 1 fixed my northernmost encampment, determining, as I had not the means of advancing further in consequence of the state of my provisions and the low condition of my horses, to employ a short period in a partial examination of the principal range, to the western base of which we had penetrated from the southward, through a considerable portion of barren interior. In exploring the mountains immediately above our tents, with a view more especially of ascertaining how far a passage could be effected over them to the shores of Moreton Bay, a remarkably excavated part of the main range was discovered, which appeared likely to prove a very practicable pass through these mountains from the eastward. Its more particular examination, however, I left to the period of a visit, by sea, to Moreton Bay, which I had already contemplated, and which I was enabled to effect in the course of the succeeding year (1829). And the brief notice of my having thus, in a most satisfactory manner, connected my sketch of the Brisbane River country with this pass, and with the lands to the westward, will be seen in another part of this paper.

The situation of my tents in the valley was determined to be as follows. Latitude, by meridional altitudes of the sun being the mean of five observations, 28° 10' 45" south. Longitude, by account corrected by bearings taken to fixed points on or near the coast-line, and compared with the mean results of several sets of distances of the sun and star antares from the moon, 152° 7' 45" E.
