e night. The
day was hot and sultry, though a heavy thundershower somewhat cooled the
air. The MacAdam Range is of sandstone, the strata of which dip about 30
degrees to the south, in which direction, as we advanced, the rock was
more slaty, and broke into rhomboidal fragments. Water is abundant in the
creeks, but the grass is scanty, and the rough surface of the sandstone
and rocky ravines renders the country difficult to traverse. Timber is
scarce, chiefly small-sized eucalypti; the cotton-tree was observed in a
few of the valleys.

2nd October.

Returning to the camp we attempted to follow one of the creeks down to
the plain on the north-west side of the range, but found the ravine too
steep and rocky for the horses to pass, and were compelled to retrace our
steps and cross several steep and rocky hills, reaching the camp at 2.0
p.m., at which time the thermometer stood at 94 degrees in the shade and
114 degrees in the sun.

3rd October.

Three of the horses had strayed, and this detained us till 11.0 a.m.,
when I started with the party, leaving Mr. H. Gregory and Bowman to look
for the missing animals. Proceeding in a south-east direction to the
crossing of the first creek, ascended the MacAdam Range, and steered
east-south-east to the second creek; the course was then north-east and
east to the head of the creek tributary to the Fitzmaurice River, and
then encamped at 3.45 p.m. At the highest point on this day's route the
aneroid stood at 29.40, and at the camp 29.55; thermometer, 88 degrees.
The higher points of the range did not exceed 100 before the highest
ridge crossed.

By a meridian altitude of a Cygni, the latitude 14 degrees 33 minutes 26

4th October.

At 10.0 a.m. Messrs. H. Gregory and Bowen reached the camp with one of
the missing horses, and, having obtained some provisions, returned to
search for the other two horses. At noon started with the party, and
followed down the creek in a south-south-east direction till 4 p.m., and
encamped at the termination of the hilly country. One of the horses,
Madman, showed symptoms of illness a short time before we started, and in
crossing the creek half a mile above where we encamped he fell down and
in less than three minutes died. This was a serious loss, as this animal
was one of the most serviceable of our horses, having stood the voyage
without losing his condition. The cause of death we were unable to
ascertain; but the probability is that
