six miles. It was not the hollow sound of an earthly explosion, or the
sharp cracking noise of falling timber, but in every way resembled a
discharge of a heavy piece of ordnance. On this all were agreed, but no
one was certain whence the sound proceeded. Both Mr. Hume and myself had
been too attentive to our occupation to form a satisfactory opinion; but
we both thought it came from the N.W. I sent one of the men immediately up
a tree, but he could observe nothing unusual. The country around him
appeared to be equally flat on all sides, and to be thickly wooded:
whatever occasioned the report, it made a strong impression on all of us;
and to this day, the singularity of such a sound, in such a situation,
is a matter of mystery to me.

FURTHER ATTEMPT TO EXPLORE THE RIVER.

On the 8th, we commenced our journey down the river, accompanied by two
men, and a pack-horse, carrying our provisions on one side and a bucket of
water on the other. Keeping in general near the stream, but making
occasional turns into the plains, we got to the brush from which the party
had turned back, about 3 p.m. Passing through, we crossed a small plain,
of better soil and vegetation than usual; but it soon gave place to the
sandy loam of the interior; nor did we observe any material alteration,
either in the country or the river, as we rode along. The flooded-gum
trees on the banks of the latter, were of beautiful growth, but in the
brushes dividing the plains, box and other eucalypti, with cypresses and
many minor shrubs, prevailed. We slept on the river side, and calculated
our distance from the camp at about twenty-six or twenty-eight miles.

The horses would not drink the river water, so that we were obliged to
give them a pint each from our own supply. On the following morning we
continued our journey. The country was generally open to the eastward, and
