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.
