were also numerous, but these birds and the
black cockatoos were the most wary of any that we met. Whilst travelling
with our bullocks through the high grass, we started daily a great number
of wallabies; two of which were taken by Charley and John Murphy,
assisted by our kangaroo dog. Brown, who had gone to the lower part of
the long pool of water near our encampment, to get a shot at some
sheldrakes (Tadorna Raja), returned in a great hurry, and told me that he
had seen a very large and most curious fish dead, and at the water's
edge. Messrs. Gilbert and Calvert went to fetch it, and I was greatly
surprised to find it a sawfish (Pristis), which I thought lived
exclusively in salt water. It was between three and four feet in length,
and only recently, perhaps a few days, dead. It had very probably come up
the river during a flood, for the water-hole in which the creature had
been detained, had no connection with the tiny stream, which hardly
resisted the absorbing power of the sands. Another question was, what
could have been the cause of its death? as the water seemed well tenanted
with small fish. We supposed that it had pursued its prey into shallow
water, and had leaped on the dry land, in its efforts to regain the deep
water. Charley also found and brought me the large scales of the fish of
the Mackenzie, and the head-bones of a large guard-fish.

June 11.--We travelled about eight miles due north. The bed of the river
was very broad; and an almost uninterrupted flat, timbered with box and
apple-gum, extended along its banks. We were delighted with the most
exquisite fragrance of several species of Acacia in blossom.

June 12.--We travelled about nine miles N.N.W. to lat. 16 degrees 55
minutes. The flats were again interrupted by sandstone ranges. One large
creek, and several smaller ones joined the river.

June 13.--We accomplished nine miles to-day in a N.N.W. direction. The
country was partly rocky; the rock was a coarse conglomerate of broken
pieces of quartz, either white or coloured with oxide of iron; it greatly
resembled the rock of the Wybong hills on the upper Hunter, and was
equally worn and excavated. The flats were limited, and timbered with
apple-gum, box, and blood-wood, where the sand was mixed with a greater
share of clay; and with stringy-bark on the sandy rocky soil; also with
flooded-gum, in the densely grassed hollows along the river. The Severn
tree, the Acacia of Expedition Range, and the l
