ome water-holes, in a small creek coming out of
the scrub below the range.

Our sportsmen gave chase to ten emus and a kangaroo on Albinia Downs: but
the rottenness of the ground prevented their capture: rather tantalizing
to hungry stomachs! I examined the basaltic rock on several spots, and
found that it contained numerous crystals of Peridot. The sand in the bed
of the river contains very minute particles of igneous rock. The slopes
of the range of Comet Creek are composed of rich black soil, in some
places without trees, in others openly timbered. Stones of a light
coloured rock, with crystals of augite, pebbles of sandstone, of
conglomerate, and of quartz, are scattered over the ground, or imbedded
in the loamy beds of the water-courses. The belt of scrub at the foot of
the slopes runs out in narrow strips towards the river, and these are
separated by box-tree thickets, and open box-tree flats. A pea-plant,
with ternate leaves, and fine yellow blossoms, was found near our camp:
Portulaca was very abundant. The bronze-winged pigeon lived here on the
red fruit of Rhagodia, and the black berries of a species of Jasmine; and
seems also to pick occasionally the seed vessel of a Ruellia, which is
very frequent on all the flats of Comet Creek.

During the night, a thunder-storm passed to the southward, but did not
reach us; at 10 o'clock we observed very vivid lightning to the westward:
the wind was from the north and north-east.

Dec. 31.--We travelled along the banks of the creek towards the
north-east, but scarcely accomplished six miles, in consequence of its
tortuous course. The water-hole which I had found when reconnoitring, was
dried up, and we were glad to find a shallow pool, of which our thirsty
cattle took immediate possession. The sand in the bed of the creek looked
moist, but no water was found, after digging to a depth of five feet. The
immediate neighbourhood of the creek was in some places open, in others
covered with a shrubby Acacia, with long glaucous, and rather fleshy
phyllodia. On both sides of the high banks are deep hollows, and chains
of ponds, surrounded with reeds; but now quite dry, and covered with the
dead shells of Limnaea, Paludina, and Unio.

Mr. Roper found an Agama, with light grey on the back, and a yellow
belly. A small Chlamy-dophorus, (Jew lizard of the Hunter) was also seen,
and is probably identical with the animal inhabiting the banks of that
river. Brown accompanied me to rec
