13TH OCTOBER.--The night was uncommonly hot, thermometer 79 deg. here, where in June last it had been as low as 7 deg.. The sky had been clouded, but the morning cleared up, and we enjoyed a cool breeze in passing amongst the sandstone gullies. On arriving at the foot of Mount Owen the day became very sultry, and there was a haziness in the air. On Mount Owen Mr. Stephenson found a new species of VIGNA with yellow flowers[*], and the SWAINSONIA PHACOIDES, conspicuous with its pink flowers. We took up our old ground over the gullies, and I went in quest of water. The ponds formerly here, had dried up, but Yuranigh found a deep one in the solid rock, containing enough for months. It was inaccessible to horses, but with a bucket we watered both these and the bullocks. The mercurial column was low, the sky became overcast, and a slight shower raised our hopes that at length rain might fall in sufficient quantity to relieve us from the difficulty about water, in returning towards Mr. Kennedy's camp. Thermometer, at sunrise, 63 deg.; at noon, 79 deg.; at 4 P. M., 76 deg.; at 9, 64 deg.;-- with wet bulb, 59 deg.. [* V. LANCEOLATA (Benth. MS.) glabra volubilis, foliolis lanceolatis reticulatis integris v. basi hastato-lobatis, pedunculis folio multo longioribus apice paucifloris, calyce glabro campanulato dentibus tubo brevioribus, carina rostrata acuta.--Flowers smaller than in V. VILLOSA, but of the same form.] 14TH OCTOBER.--During the night several smart showers fell, and at daybreak the sky seemed set for rain. When we set off it rained rather heavily. I took a new direction, and got into a gully which led to our former track of 17th June. Crossing it, I passed into the bed of the Maranoa, and followed it down with the carts, until we arrived at the large pond in solid rock, to which I had sent the bullocks on the 18th June. Here we encamped, and I marked a tree with the number 74, as it might be necessary on future occasions to refer to where a permanent supply of water may be found in that part of the country. Thermometer, at sunrise, 60 deg.; at noon, 71 deg.; at 4 P. M., 66 deg.; at 9, 52 deg.;--with wet bulb, 48 deg..
