soil proved to be a stiff clay; the reeds were closely embodied, and from
ten to twelve feet high; the waters were in some places ankle deep, and in
others scarcely covered the surface. They were flowing in different
points, with greater speed than those of the river, which at once
convinced me that they were not permanent, but must have lodged in the
night during which so much rain had fallen. They ultimately appeared to
flow to the northward, but I found it impossible to follow them, and it
was not without difficulty that, after having wandered about at every
point of the compass, I again reached the boat.

CAUSES OF THE FAILURE OF THE RIVER.

The care with which I had noted every change that took place in the
Macquarie, from Wellington Valley downwards, enabled me, in some measure,
to account for its present features. I was led to conclude that the waters
of the river being so small in body, excepting in times of flood, and
flowing for so many miles through a level country without receiving any
tributary to support their first impulse, became too sluggish, long ere
they reached the marshes, to cleave through so formidable a barrier; and
consequently spread over the surrounding country--whether again to take
up the character of a river, we had still to determine. Unless, however,
a decline of country should favour its assuming its original shape, it was
evident that the Macquarie would not be found to exist beyond this marsh,
of the nature and extent of which we were still ignorant. The loss of my
barometer was at this time severely felt by me, since I could only guess
at our probable height above the ocean; and I found that my only course
was to endeavour to force my way to the northward, to ascertain, if I
could, from the bottom of the marshes; then penetrate in a westerly
direction beyond them, in order to commence my survey of the S.W.
interior. I was aware of Mr. Hume's perseverance, and determined,
