We proceeded from this camp towards the southern extremity of Mount Cunningham, under which a small branch of the Lachlan passes so close that the party was occupied an hour and a half in removing rocks to open a passage for the carts. We then got into an open country in which we soon saw the same dry branch of the Lachlan before us; but we turned more to the north-west until we reached a slightly undulated surface. No branch of the river extends to the northward of Mount Cunningham as shown on Mr. Oxley's map; but a small tributary watercourse, then dry, skirts the eastern side of the hill, and enters that branch of the Lachlan which we were upon. Yesterday and this day had been so excessively hot (82 degrees in the shade) that I confidently anticipated rain, especially when the sky became cloudy to the westward, while the wind blew steadily from the opposite quarter. A dense body of vapour in the shape of stratus, or fall cloud of the meteorologist, was at the same time stretching eastward along the distant horizon on both sides of us. After crossing some sound, open plains of stiff clay, guided by the natives, we gained an extensive pond of muddy water and encamped on a hill of red sand on its northern bank, and under shelter of a grove of callitris trees. RAIN. The wind now began to blow and the sky, to my great delight, being at length overcast, promised rain enough to fill the streams and waterholes: at twilight it began to come down. In the woods we passed through this day we found a curious willow-like acacia with the leaves slightly covered with bloom, and sprinkled on the underside with numerous reddish minute drops of resin.* The Pittosporum angustifolium we also recognised here, loaded with its singular orange-coloured bivalved fruit. (*Footnote. This is allied in some respects to A. verniciflua and exudans, but is a very distinct and well-marked species. A. salicina, Lindley manuscripts; glaucescens, ramulis angulatis, phyllodiis divaricatis lineari et oblongo-lanceolatis utrinque angustatis obtusissimis uninerviis venulis pinnatis: ipso apice glandulosis subtus resinoso-punctatis, capitulis 3-5 racemosis phyllodiis triplo brevioribus.) March 31. It rained during the night and this morning the sky seemed as if it would continue; the mercury in the barometer also falling, we halted. On a dry sandhill, with wood and water at hand, we were well prepared to await the results of a flood; some good grass also was found for the cattle on firm ground at the distance of about two miles.
