12TH FEBRUARY.--We broke up our encampment on Cannonba ponds, where we had greatly recruited ourselves, both men and cattle, and crossing the channel of the water-course near our camping ground, we travelled over open grassy plains towards the river Macquarie. At thirteen miles we reached the western branch of Duck Creek, or "Marra," a name by which it is universally known to natives and stockmen. Of this we crossed several branches, from which it would appear as if the name was derived from that of the hand, which is the same, especially as natives sometimes hold up the hand and extend the fingers, when they would express that a river has various branches or sources. I went on with an advanced party towards the Macquarie, and encamped on the bank of that river at 5 P. M. The thick grass, low forests of yarra trees, and finally the majestic blue gum trees along the river margin, reminded me of the northern rivers seen during my journey of 1831. Still even the bed of this was dry, and I found only two water holes on examining the channel for two miles. One of these was, however, deep, and we encamped near it, surrounded by excellent grass in great abundance. The Macquarie, like other Australian rivers, has a peculiar character, and this was soon apparent in the reeds and lofty yarra trees growing on reedy plats, and not, as usual in other rivers, on the edge of water-worn banks. The channel was here deep and dry. We found this day, in the scrubs by Marra Creek, the ACACIA SALICINA, whereof the wood has a strong perfume resembling violets, also a new small-leaved KOCHIA with intricate branches.[*] Thermometer at sunrise, 47 deg.; at 4 P.
