the creek offers below our camp a very fair section. The hill is a coarse grained sandstone, the upper strata in the creek are a yellow clayy sandstone, which turns into claystone. Both the latter contain a great number of  impressions of waterplant with parallel veins and I observed several impressions of Equisetums [?] or perhaps Calanute [?] with distinct articulations but no visible sheath. If we remember that they occur at the Condamine, that I found them at the [indecipherable] {Calverts Plains near fields of Everlastings} and that the coal exists in the Mackenzie, we easily conclude that the whole country is of one sandstone formation with generally undisturbed almost horizontal layers.
4 Febr. After having taken leave from our poor good horse Lavender, which remained in one of the most delightful places of Australia, I travelled up the creek to the WNW changing higher up to the NW, I did not hit our former gap, but came at once into easterly creeks. This made me believe, that I had to go still more to the Westward and I crossed consequently very rugged ridges along the upper part of Castle Creek, avoiding all the eastern waters. When I however descended along a gully I came to Brush creek, with dense vinebrush on both sides, which soon turned out to be a westerly water, I had to beat back and having come on an easterly gully I descended until it opened and encamped on an open spot of Silverleaved Ironbark forest with fine pools pf water in rocky holes, which had been collected during the late rains. During the afternoon I followed this watercourse down and found that it was the father [?] flat of Zamia [?] Creek along which I had descended to the latter creek 2 years ago. - Several interesting little trees were observed in the scrub and a visible change of the vegetation took place. A prickly acacia resembling a little a. farnascasia [?], the arborescent garnia [?], the smaller Bottle tree [?]
