At our noon halt Mr. Moore and myself ascended a hill of red schist of
300 or 400 feet elevation, in latitude 23 degrees 57 minutes 15 seconds,
which had been named Mount Thompson. From this hill we had an extensive
view of the surrounding country; close to the northern foot the river
divided into two nearly equal parts--one coming from the north-north-east
we named the Alma. To the north, just resting on the edge of the tropic,
lay a compact range through which there was apparently but one break, and
that was on the line of the Alma; from the southern face of this range,
which extends nearly forty miles to the eastward, numerous streams take
their rise and flow southward into the Lyons, which had altered its
course and was now coming from the east-south-east. Our intention had
been to keep our course until we had touched upon the tropic; but as the
Alma was not running, we decided upon following the main course of the
stream, and accordingly adopted an easterly course for the remainder of
the day, encamping about six miles to the east of Mount Thompson. The
river here was much narrower, with a rocky bed containing many pools of
permanent character, overshadowed by flooded-gums of large growth, much
resembling the Eucalyptus piperita of the flats of the Swan, but not
possessing the same pungent leaf.

Found our latitude to be 23 degrees 58 minutes 32 seconds, and longitude
111 degrees east by account.
