W. We encamped on open forest land in lat. 26° 54' 16" S. It was only
during the last two days that I could perceive in the barometer, any
indication that we were rising to any higher level above the sea than
that of the great basin, in which we had journeyed so long, and the
difference was still but trifling, as indicated by not more than six or
seven millimetres of the Syphon barometer; our actual height above the
sea being 737 feet. Thermometer, at sunrise, 19°; at 4 P. M., 67°.

6TH MAY.--The banks of the Cogoon became more open, and the slopes less
abrupt as we advanced. They frequently consisted of a mixture of sand, at
a height of twenty feet above its bed; where it occupied a section of
considerable width, as much, perhaps, as 100 yards between bank and bank.
On these rounded off banks or bergs of forest land, Youranigh drew my
attention to large, old, waterworn, trunks of trees, which he showed me
had been deposited there by floods. As they were of a growth and size
quite disproportioned to other trees there, I was convinced that they
were the debris of floods; and, consequently, that a vast body of water
sometimes came down this channel. This native was taciturn and observant
of such natural circumstances, to a degree that made his opinion of value
in doubtful cases. Such, for instance, as which of two channels, that
might come both in our way, might be the main one; thus my last resource,
when almost "in a fix," was to "tomar el parecer," as they say in Spain,
of this aboriginal, and he was seldom wrong. At length, the cheering
expanse of an open country appeared before us, and a finely shaped hill,
half-covered only, with bushes. On reaching an elevated clear part, I saw
extensive downs before me. The river turned amongst woods to the
eastward, and I continued on our route to the north, sure of meeting with
it again, as some fine forest ridges hemmed in the valley to the
eastward. Besides the hill already mentioned (which I named Mount
Inviting), there was a curious red cone some miles to the westward,
