Granite. — Succeeds the serpentine, of lightcolour; feldspar de- 
composed ; 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 Bank- 
sias and scrub. 
Mica Slate. — Colour dark brown, approaching red ; mica glit- 
tering. The hills inclosing 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 perpen- 
dicular 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 outer- 
most 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 neighbour- 
ing 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 ot the 
elevations of the more northern interior.
