the only exposed section the sandstone dipped to the north 5
degrees to 15 degrees. We also crossed a hill of porphyry which was
remarkable for the regularity of cleavage into thick lamina, which were
vertical, with a north and south strike; but though it had the appearance
of a stratified rock, its structure was perfectly crystalline. About
noon, granite, containing large plates of mica, was observed in some of
the gullies.

23rd October.

At 7.0 a.m. steered south-south-east and south-east over ridges of
sandstone, timbered with ironbark and thinly grassed, for an hour and a
half; again struck the river and passed at the foot of some limestone
hills and ridges; this limestone contained fragments of shells and coral.
Altering the course to south, traversed fine open flats half a mile to a
mile wide, beyond which the country rose into low ridges of limestone. At
noon basalt appeared covering the limestone and sandstone. The steep
slope which formed the boundary of this rock was very rugged; but the
level surface was covered with black soil and well grassed. At 12.55 p.m.
camped in a fine grassy flat, walled in by steep rocks of basalt. We
experienced some difficulty in watering the horses, as the bank of the
river was so steep that they frequently fell back into the river in
ascending it. The limestone rocks seen on this day's journey appear to
rise from beneath the sandstones, some of which are very hard and
close-grained; it dips about 10 degrees to the west and some of the
adjacent sandstones 20 degrees west, in well-defined strata. The basalt
covers all the other rocks, filling up the former inequalities of the
surface and forming a perfectly level plain; where the softer sandstones
were in contact, they were only baked into a coarse brick-like mass,
which had had much the appearance of having been formed from the alluvial
banks of the river.

Latitude by e Pegasi and a Gruis 19 degrees 42 minutes 10 seconds;

DUCKS, GEESE, AND PELICANS.

24th October.

Leaving our camp at 6.0 a.m., steered south-south-east over well-grassed
basaltic flats, timbered thinly with ironbark, etc.; the soil a red loam.
At 9.0 a.m. came on a large reedy lagoon or swamp with considerable
patches of shallow open water, on which were great numbers of ducks,
geese, pelicans, etc. A broad and deep stream flowed from it to the
south
