river. This ridge is a
remarkable feature, extending north and south, and I expected to see some
tributary from the north entering the river here; but we crossed on the
east side of the ridge only a wide, dry and grassy hollow, which was
however evidently the channel of a considerable body of water in times of
flood, as appeared by marks on the trees which grew along the banks. All
were of the dwarf box kind, named goborro by the natives, a sort of
eucalyptus which usually grows by itself on the lower margins of the
Darling and Lachlan, and other parts subject to inundation, and on which
the occasional rise of the waters is marked by the dark colour remaining
on the lower part of the trunk. In the bed of the Lachlan at the junction
of the channel near Kalingalungaguy I found quartz rock.

MR. STAPYLTON OVERTAKES THE PARTY.

We had not proceeded far beyond that ridge when Mr. Stapylton overtook
the party, having travelled in great haste from Sydney to join us as
second in command, in compliance with my letter of instructions sent from
Buree. Mr. Stapylton was accompanied by two stockmen, having left his own
light equipments at Cordowe, a station above Mount Cunningham. On the
plains which we crossed this day grew in great abundance that beautiful
species of lily found in the expedition of 1831, and already mentioned
under the name of Calostemma candidum,* also the Calostemma luteum of Ker
with yellow flowers.

At nine miles we crossed some granite rocks, evidently a part of the
ridge of Tarratta, thus exhibiting a uniformity in the granite with the
general direction of other ridges, which is about north-north-east. The
strike is between north and north-east; the dip in some places being to
the west, and in others to the east, at great inclinations. The ridge of
Kalingalungaguy consists of quartz, clay-slate, and the ferruginous
sandstone, but I observed in the bed of the river a trap-dyke extending
to the Bolloon ridge. Of the few low hills about the Lachlan it may be
observed that they generally range in lines crossing the bed of that
river. Mount Amyot is a ridge of this sort, being connected to the
southward with Mount Stewart and Nyororong; and to the northward with the
high ground separating the Bogan from the Goobang; the latter creek also
forcing its way through the same
