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
