orward and found a FOURTH channel, deep, wide,
and full to the brim. In vain did Tally-ho (trumpeter, master of the
horse, etc. to the party) dash his horse into this stream in search of a
bottom; though at last one broad favourable place was found where the
whole party forded at a depth of not more than 2 1/2 feet. Beyond these
channels another similar one still obstructed our progress; but this we
also successfully forded, and at length we found rising ground before us,
consisting of an open plain which extended to the base of the mountains.
On its skirt we pitched our tents at a distance of not quite one mile and
a half from our last camp; a short journey certainly, but the passage of
the five branches of the Wimmera was nevertheless a good day's work. I
had frequently observed in the Australian rivers a uniformity of
character throughout the whole course of each, and the peculiarities of
this important stream were equally remarkable, it being obviously the
same we had crossed in three similar channels when on our way to Mount
William, twenty miles above this point. The shrubs on the banks at the
two places were also similar.

ASCEND MOUNT ZERO.

July 20.

While Mr. Stapylton conducted the party across the plains in a
west-south-west direction I proceeded towards Mount Zero, the most
western extremity of the mountain range and distant from our camp 8 1/2
miles. I found this hill consisted also of highly micaceous sandstone;
the whole being inclined towards the north-west. Having planted my
theodolite on the summit I intersected various higher points to the
eastward, and also a very remote, isolated hill on the low country far to
the northward which I had also seen from Mount William, and from several
stations on our route. Several specimens of shrubs and flowers that had
not been previously seen by us were gathered on the sides of this rocky
hill. Among them was a very singular hairy Acacia covered with a
profusion of the most brilliant yellow flowers. In some respects it
resembled A. lanigera, but it proved upon examination to be undescribed.*

An isolated mass appeared to the westward, having near its base a most
remarkable rock resembling a mitre. Beyond this the dista
