as well as from its increased size, seemed to intimate that it had
successfully struggled through the broken country in which it rises,
and that it would henceforward meet with fewer interruptions to its
course. It still, however, preserved all the characters of a mountain
stream; having alternate rapids and deep pools, being in many places
encumbered with fallen timber, and generally running over a shingly
bed, composed of rounded fragments of every rock of which the
neighbouring ranges were formed, and many others that had been swept by
the torrents down it. The rock formation of the hills upon its right
continued of that chlorite schist which prevailed near Mr. Whaby's,
which I have already noticed, and quartz still appeared in large
masses, on the loftier ranges opposite, so that the geology of the
neighbourhood could not be said to have undergone any material change.
It might, however, be considered an extraordinary feature in it, that a
small hill of blue limestone existed upon the left bank of the river.
The last place at which we had seen limestone was at Yass, but I had
learned from Mr. Whaby, that, together with whinstone, it was abundant
near a Mr. Rose's station on the Dumot, that was not at any great
distance. The irregularity, however, of the intervening country, made
the appearance of this solitary rock more singular.

Although the fires of the natives had been frequent upon the river,
none had, as yet, ventured to approach us, in consequence of some
misunderstanding that had taken place between them and Mr. Stuckey's
stockmen. Mr. Roberts' stockmen [these men had lately fixed themselves
on the river a little below Mr. Whaby's], however, brought a man and a
boy to us at this place in the afternoon, but I could not persuade them
to accompany us on our journey--neither could I, although my native boy
understood them perfectly, gain any particular information from them.

In consequence of rain, we did not strike the tents so early as usual.
At 7 a.m. a heavy thunder storm occurred from the N.W. after which the
sky cleared, and we were enabled to push forward at 11 a.m., moving on
a general W.N.W, course, over rich flats, which, having been moistened
by the morning's showers, showed the dark colour of the rich earth of
which they were composed. Some sand-hills were, however, observed near
the river, of about fifteen feet in elevation, crowned by banksias; and
the soil of the flats had a very partial mixture
