ese granite rocks that the best grazing is found.

Greywacke.--Colour grey, of light hue, or dark, with black specks.
Soft.--Composition of a part of the ranges that form the valley of the
Morumbidgee.

Serpentine.--Colour green of different shades, striped sulphur yellow;
slaty fracture, soft and greasy to the touch. Forms hills of moderate
elevation, of peculiarly sharp spine, resting on quartz. Composition of
most of the ranges opposite the Doomot River on the Morumbidgee, in
lat. 35 degrees 4 minutes and long. 147 degrees 40 minutes.

Quartz.--Colour snow-white; formation of the higher ranges on the left
bank of the Morumbidgee, in the same latitude and longitude as above;
showing in large blocks on the sides of the hills.

Slaty Quartz, with varieties.--Found with the quartz rock, in a state
of decomposition.

Granite.--Succeeds the serpentine, of light colour; feldspar
decomposed; mica, glittering and silvery white.

Sandstone, Old Red.--Composition of the more distant ranges on the
Morumbidgee. Forms abrupt precipices over the river flats; of sterile
appearance, and covered with Banksias and scrub.

Mica Slate.--Colour dark brown, approaching red; mica glittering. The
hills enclosing Pondebadgery Plain at the gorge of the valley of the
Morumbidgee, are composed of this rock. They are succeeded by

Sandstone.--Which rises abruptly from the river in perpendicular
cliffs, of 145 feet in height.

Jasper and quartz.--Colour red and white. Forms the slope of the above
sandstone, and may be considered the outermost of the rocks connected
with the Eastern or Blue Mountain Ranges. It will be remembered that
jasper and quartz were likewise found on a plain near the Darling
River, precisely similar to the above, although occurring at so great a
distance from each other.

Granite.--Light red colour; composition of a small isolated hill, to
all appearance wholly unconnected with the neighbouring ranges. This
specimen is very similar to that found in the bed of New-Year's Creek.

Breccia.--Silicious cement, composed of a variety of pebbles. Formation
of the most WESTERLY of the hills between the Lachlan and Macquarie
Rivers. This conglomerate was also found to compose the minor and most
westerly of the elevations of the more northern interior.

Chrystallised Sulphate of Lime.--Found embedded in the deep alluvial
soil in the banks of the Morumbidgee River, in lat. 34 degrees 30
minutes S., and long. 144 degrees 55
