m and salsolae.
Nothing could exceed the apparent barrenness of these plains, or the
cheerlessness of the landscape. We had left all high lands behind us, and
were now on an extensive plain, bounded in the distance by low trees or by
dark lines of cypresses. The lofty gum-trees on the river followed its
windings, and, as we opened the points, they appeared, from the peculiar
effect of a mirage, as bold promontories jutting into the ocean, having
literally the blue tint of distance. This mirage floated in a light
tremulous vapour on the ground, and not only deceived us with regard to
the extent of the plains, and the appearance of objects, but hid the
trees, in fact, from our view altogether; so that, in moving, as we
imagined, upon the very point or angle of the river, we found as we neared
it, that the trees stretched much further into the plain, and were obliged
to alter our course to round them. The heated state of the atmosphere, and
the sandy nature of the country could alone have caused a mirage so
striking in its effects, as this,--exceeding considerably similar
appearances noticed during the first expedition. The travelling was so
heavy, that I was obliged to make a short day's journey, and when we
struck the river for the purpose of halting, it had fallen off very much
in appearance, and was evidently much contracted, with low banks and a
sandy bed. It was difficult to account for this sudden change, but when
I gazed on the extent of level country before me, I began to dread that
this hitherto beautiful stream would ultimately disappoint us.
EXCURSION TOWARDS A RIDGE OF HILLS.
I had deferred my intended excursion to the hills under which I imagined
Mr. Oxley had encamped, until we were out of sight of them, and I now
feared that it was almost too late to undertake it, but I was still
anxious to determine a point in which I felt considerable interest. I was
the more desirous of surveying the country to the northward, because of
the apparent eagerness with which the natives had caught at the word
Colare, which I recollected having heard a black on the Macquarie make
use of in speaking of the Lachlan. They pointed to the N.N.W., and making
a sweep with the arm raised towards the sky, seemed to intimate that a
large sheet of water existed in that direction; and added that it
communicated with the Morumbidgee more to the westward. This information
confirmed still more my impressions with regard to Mr. Oxley's line
