nothing could be distinguished, and from which it is safest to go forward in the known general course of the chain of ponds. We again encamped under Mount Mudge, where I perceived that a projecting portion of white rock on the summit, had fallen since I had stood upon it; and that the avalanche of rock had strewed the woody side of the mountain with white fragments down to the very base. In the sheltered ravine below, a curious new CASSIA formed a shrub six feet high.[*] Thermometer, at sunrise, 39 deg.; at noon, 70 deg.; at 4 P.M., 82 deg.; at 9, 56 deg.;--with wet bulb, 50 deg.. [* C. ZYGOPHYLLA (Benth. MS.) glabra vel pube tenuissima subcanescens, foliolis unijugis linearibus planis crassis, glandula inter foliola parva depressa, racemis petiolo brevioribus 2-4-floris.--Near C. NEMOPHILA Cunn.; but there appear never to be more than one pair of leaflets, the plant is smoother, the leaflets longer, and the glands different.] 30TH AUGUST.--The old track guided the party, while I preceded it to sketch one or two landscapes. A fine breeze blew from the northward, and goodly clouds seemed to promise rain. I completed my drawings before the arrival of the carts; and on their coming up I conducted them to a spot where we encamped, on the left bank of the creek, or opposite to camp LI., being resolved to seek a better and more direct way to the plains, than that down the bed of Balmy Creek, which we formerly found so difficult. As soon as I had chosen a spot for the tents, I took a ride, accompanied by Mr. Stephenson and Yuranigh, to explore the ravines eastward of that of Balmy Creek, and which led in a more direct line towards the plains of the Claude. We found the precipices in this direction much lower. After riding a few miles, we could ride up one of the points, and following the ridge we had ascended (which was thickly covered with brigalow), we at length got to an open forest, and once more saw the open plains before us. In returning, I selected, with Yuranigh's able assistance, a smaller valley, by which I hoped to succeed in conducting the carts next day, so as to avoid the ascent of the brigalow range. The barometer at this camp had fallen ten millimetres lower than the point at which the mercury stood formerly at the adjacent camp (marked LI.). By the side of the water-course, we found the ACACIA DORATOXYLON and also the ACACIA CONFERTA. The valley was gay with the ultramarine blue flowers of a new species of HOVEA[*]; and on rich soil we saw also the PODOLEPIS ACUMINATA? D. C. A shrub with long curved leaves and singular zigzag stems, was ascertained to be the ACACIA MACRADENIA, a very striking new species; and on Balmy Creek we found also a new BOSSIOEA, with deep red flowers.[**] Thermometer, at sunrise, 59 deg.; at noon, 83 deg.; at 4 P.M., 81 deg.; at 9, 62 deg.; with wet bulb, 54 deg..
