was much the same as that of the
first (about 39 E. of N.). The bed and ponds increased; and after
following it up about eleven miles, I encamped the party, and rode
northward to ascertain if it was likely to change its course. In ten
minutes, I came upon a splendid reach, extending north-west as far as I
could see it. Lat. of our camp, 27 deg. 42' 42" S. Thermometer, at sunrise,
37 deg.; at noon, 69 deg.; at 4 P. M., 72 deg.; at 9, 57 deg.;--with wet bulb, 55 deg..
28TH APRIL.--Masses of a ferruginous rock extended across the river bed
like a dyke, in a N. W. and S. E. direction; and as the river here broke
through these rocks, changing, at a sharp angle, its course to the S. W.,
it seemed probable that the general course from above might be parallel
to these rocks. Continuing along the bank, we found the reaches large,
full of water; the country clear of scrub and covered with luxuriant
grass. One singular flat sweeping round to the W. S. W. was covered with
the rich grass PANICUM LOEVINODE. The tropical PEROTIS RARA, a delicate
grass, producing long purple tufts of reflexed bristles, was also here
observed. The general direction of the river was towards the N. W., and
whenever it took any turn towards the east, I continued to travel
northward, and thus, on three occasions, came upon its bank again,
cutting off detours I must otherwise have described in following its
course. We encamped on a beautiful spot, the sight of which would have
rejoiced the heart of a stockholder. A fresh westerly breeze blew during
the day, and we were as free from the annoyance of heat, as if we had
been in England during the same month. Latitude 27 deg. 32' 37" S. The
direction of the river's course was uncommonly straight, and its long
sweeping reaches, full of water, seemed capable of being rendered
available for the purpose of forming water communications. The surface of
the adjacent country presented a thin deposit of sand, near the river,
attesting the great height to which its waters sometimes rise; and minor
features of ground near, showed, in their water-worn sections, that they
had been wholly deposited by the river. Thermometer, at sunrise, 39 deg.; at
4 P. M., 69 deg.; at 9, 48 deg.;--with wet bulb, 46 deg..
29TH APRIL.--The tendency of the soft earth of the banks to break into
gullies, branching back into impervious scrubs, was such as to prevent me
from either seeing much of the river during this day's journey, or
pursuing a
