The day was hot and we killed several large snakes of the species eaten by the natives. I observed that our guides looked at the colour of the belly when in any doubt about the sort they preferred; these were white-bellied, whereas the belly of a very fierce one with a large head, of which Piper and the others seemed much afraid, was yellow. On cutting this snake open two young quails were found within: one of them not being quite dead. The country we crossed during the early part of the day was at least as fine as that we had left. We passed alternately through strips of forest and over open flats well watered, the streams flowing southward; and at nine miles we crossed a large stream also flowing in that direction: all these being evidently tributaries to that on which we had been encamped. Beyond the greater stream, where we last crossed it, the country presented more of the mountain character, but good strong grass grew among the trees, which consisted of box and lofty bluegum. After making out upwards of eleven miles, we encamped in a valley where water lodged in holes and where we found also abundance of grass. We were fast approaching those summits which had guided me in my route from Mount Cole, then more than fifty miles behind us. Like that mountain these heights also belonged to a lofty range, and like it were beside a very low part of it, through which I hoped to effect a passage. Leaving the party to encamp I proceeded forward in search of the hill I had so long seen before me, and I found that the hills immediately beyond our camp were part of the dividing range and broken into deep ravines on the eastern side. Pursuing the connection between them and the still higher summits on the north-east, I came at length upon an open valley enclosed by hills very lightly wooded. This change was evidently owing to a difference in the rock which was a fine-grained granite, whereas the hills we had recently crossed belonged chiefly to the volcanic class of rocks, with the exception of the range I had traversed that evening in my way from the camp, which consisted of ferruginous sandstone. With the change of rock a difference was also obvious in the shape of the hills, the quantity and quality of the water, and the character of the trees. The hills presented a bold sweeping outline and were no longer broken by sharp-edged strata but crowned with large round masses of rock. Running water was gushing from every hollow in much greater abundance than elsewhere; and lastly the timber, which on the other ranges consisted chiefly of ironbark and stringybark, now presented the shining bark of the bluegum or yarra and the grey hue of the box. The Anthisteria australis, a grass which seems to delight in a granitic soil, also appeared in great abundance, and we also found the aromatic tea, Tasmania aromatica, which represents in New Holland the winter's bark of the southern extremity of South America.
