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.
Nov.

7 .-- The first two hours of the day were cloudy, but it cleared up and became very hot; the atmosphere was hazy and sultry; cumuli with undefined outlines all round the horizon: wind from south-west and south.
I travelled west by north about eight miles, along the foot of Bastard-box and silver-leaved Ironbark ridges.
