The trio who had visited us some days before, were all thoughtful observation; these were merry as larks, and their white teeth, constantly visible, shone whiter than even the cockatoo's feathers on their brows and chins. Contrasted with our woollen-jacketted, straw- hatted, great-coated race, full of work and care, it seemed as if nature was pleased to join in the laugh, at the expense of the sons of art. Sun never shone upon a merrier group of mortals than these children of nature appeared to be. One amongst them was a fine powerful fellow, whose voice sounded so strongly, that it seemed as if his very whisper might be heard half a mile off. The old man remained by our fire all night; the others who, as I understood, were all his sons, had departed about 11 P. M., having left their gins in the vicinity. Thermometer, at sunrise, 22 deg.; at noon, 76 deg.; at 4 P. M., 59 deg.; at 9, 35 deg.. 12TH MAY.--I took a ride in the direction where I hoped to find a river flowing towards the interior, according to my observations at Mount Bindango. I rode over an open plain, or open forest country, soon found the dells marked by water-courses, and, at length, the channel of a river, with the Yarra trees. Following this new channel downwards a short way, I found the beds of the ponds moist, and seven emus, running from one a-head of me, first indicated the situation of a large pond; from which three wood-ducks also waddled away as I approached it. This water was only fifteen miles from where I had left the party encamped, to which I hastened back with the tidings of a discovery that was likely to expedite so much our momentous journey. Thermometer, at sunrise, 30 deg.; at noon, 81 deg.; at 4 P. M., 59 deg.; at 9, 52 deg.;--with wet bulb, 51 deg.. Height above the sea, 1168 feet.
