We travelled along the valley of the river about ten miles, in a west-northerly course; our latitude of this day being 26 degrees 3 minutes 44 seconds Fine box and apple-tree flats were on both sides of the creek, now deserving the appellation of a "River," and which I called the "Dawson," in acknowledgment of the kind support I received from R. Dawson, Esq., of Black Creek, Hunter's River. At the foot of the ridges some fine lagoons were observed, as also several plains, with the soil and the vegetation of the Downs, but bounded on the northward by impenetrable Bricklow scrub. In a watercourse, meandering through this scrub, sandstone cropped out, in which impressions of fossil plants were noticed by me. It was interesting to observe how strictly the scrub kept to the sandstone and to the stiff loam lying upon it, whilst the mild black whinstone soil was without trees, but covered with luxuriant grasses and herbs; and this fact struck me as remarkable, because, during my travels in the Bunya country of Moreton Bay, I found it to be exactly the reverse: the sandstone spurs of the range being there covered with an open well grassed forest, whilst a dense vine brush extended over the basaltic rock. The phenomenon is probably to be explained by the capability of the different soils of retaining moisture, and, at the same time, by taking into account the distance of the localities from the seacoast. I called these plains "Calvert's Plains," after my companion, Mr. Calvert. Farther to the westward we passed over open ridges, covered with Bastard-box and silver-leaved Ironbark: the former tree grows generally in rich black soil, which appeared several times in the form of ploughed land, well known, in other parts of the colony, either under that name, or under that of "Devil-devil land," as the natives believe it to be the work of an evil spirit.
