Continued our route at 6.5 a.m., and followed the river northward till
8.10, when it turned to the north-west; the country consisted of nearly
level grassy plains of various elevations, separated by low rocky ridges
of sandstone and basalt, the whole well grassed, except some small
patches where triodia prevailed; at 11.0 altered the course to average
north-west by west, and at 1.30 p.m. camped at a small gully with a
little water remaining from a recent shower. The horses suffered much
from the heat, as the air was very moist; at 1.40 there was a shower of
rain, and the temperature was reduced from 95 degrees to 84 degrees.

Latitude by Vega 16 degrees 35 minutes 8 seconds.

Started from the camp at 6.30 a.m., steering west-south-west; at first
sandstone prevailed, and triodia replaced the grass, but at two miles
again entered the basaltic country, which was well grassed but very
stony, and forming flat-topped hills of small elevation; the basalt
appeared to be interstratified with sandstone, the latter much altered at
the line of contact. At 9.15 came on the bank of the river, which was
running in a deep channel with a dense line of pandanus, fig-trees,
terminalia, flooded-gum, and melaleuca; followed the valley of the river
to the north-west till noon, and camped at the foot of the hill which we
had ascended, at the most southern point attained in December, 1855;
ascended the hill and took the bearings, as on the former occasion the
rain had obscured the features of the country.

Having connected this part of our route with that of December last, at
6.20 a.m. commenced our return up the river, crossing to the left bank at
7.15; the water was running strong twenty yards, and one to two feet
deep; in examining the ford my horse trod on the back of a large
alligator, which seemed to be equally astonished as the horse at this
unexpected meeting; I then proceeded up the river a mile and a half and
halted, as Mr. H. Gregory, who I had sent to examine the river in another
part, had not come up with the party, but he shortly after overtook us,
having found a good ford lower down the river; at 4.0 p.m. resumed our
journey, and at dusk encamped in the bed of a large creek, which joined
the Victoria from the south-south-
