15TH OCTOBER.--Last evening the wind blew keenly, and the night was cold, the temperature very different from that experienced of late. The morning presented a thick haze and drizzling rain, this kind of weather being rather favourable for crossing the loose sandy surface, which the men dreaded, remembering how it had before affected their eyes. I at first endeavoured to travel this day along the river bank, but I found its course so tortuous, and the country on its banks so hilly and rocky, that I left it, and proceeded in a direction that would intersect the former track. We thus passed through a fine open forest, fell in with our old track at a convenient point, and found water still in the pond at the camp of 15th June, where we therefore again set up our tents. The sky had cleared up, and the air was pleasantly cool, with a fine breeze blowing from S.E. On the river bank, we observed this day the native bramble, or Australian form of RUBUS PARVIFOLIUS, L. A small nondescript animal ran before Mr. Stephenson and myself this morning. It started from a little bush at the foot of a tree, had large ears, a short black tail, ran like a hare, and left a similar track. It was about the size of a small rabbit. The death of our dogs on the Bogan, under the intense heat and drought, had been a very serious loss to us, as we found on many occasions like this; and where kangaroos, of apparently rare species, escaped from us from our having no dogs. We were, also, from want of such dogs, much more exposed to attacks of the natives. Evening again cloudy. Thermometer, at sunrise, 45 deg.; at noon, 64 deg.; at 4 P.M., 67 deg.; at 9, 57 deg.;-- with wet bulb, 50 deg..
