Nov. 18.--Clouds gathered from the west and north-west, a few drops of
rain fell, and a few low peals of thunder were heard; but, although
charged with electric fluid, and, in appearance, threatening an
approaching thunder-storm, no discharge of lightning took place. We were
very much annoyed and harassed, during the evening and the early part of
the night, by sand-flies and mosquitoes; but the clear night grew so
cold, that these great enemies of bush comforts were soon benumbed. The
latitude of the camp of the 18th November was 25 degrees 30 minutes 11
seconds.

Nov. 19.--No air stirring, night very cold and bright; dew heavy; the
surface of the creek covered with vapour; the water very warm.

Having no apparatus for ascertaining the height of our position above the
level of the sea, this very interesting fact could not be determined;
but, from the cold experienced, at a period so near the summer solstice,
the elevation must have been very considerable.

We travelled during the day in a westerly direction over a level country,
partly covered with reeds and fat-hen, and came to a broad sandy creek,
which turned to the south-east and south. Having crossed it, we passed
several large lagoons and swamps covered with plovers and ducks; and, at
a short mile farther, came again on the creek, which now had a deep
channel and a broad sandy bed lined with casuarinas and flooded-gum
trees. I called this "Robinson's Creek." At its left bank, we saw a wide
sheet of water, beyond which rose a range densely covered with scrub: I
called them "Murphy's Lake and Range," after John Murphy, one of my
companions.

I believe that Robinson's Creek is a westerly water; and, if so, it is
very remarkable that the heads of Palm-tree Creek, which flows to the
eastward, should be scarcely a mile distant; and that the interesting
space, separating the two systems of waters, should be, to all
appearance, a dead level.

I had descended--from a scrubby table land, the continuation of Darling
Downs--into a system of easterly waters. I had followed down the Dawson
for a considerable distance, and then, following up one of its creeks,
found myself again on westerly waters. I could not decide, to my entire
satisfaction, whether my views were right; for the country was difficult
for reconnoitring; and I was necessarily compelled to move quickly on, to
accomplish the object of my expedition: but it is a very interesting
point for geographical re
