(*Footnote. Mr. James Collits of Mount York.) Mount Amyot had the appearance of granite from the plains, but I found that it consisted of the ferruginous sandstone. It is the southern extremity of a long ridge elevated not more than 200 feet above the plains at its base. We encamped at a bend of the river, on the border of a small plain named Merumba in latitude 33 degrees 19 minutes 16 seconds South. Variation 8 degrees 54 minutes 15 seconds East. We were here disturbed by herds of cattle running towards our spare bullocks and mixing with them and the horses. In no district have I seen cattle so numerous as all along the Lachlan; and notwithstanding the very dry season, they were nearly all in good condition. We found this day, near the river bed, a new herbaceous indigo with white flowers and pods like those of the prickly liquorice (Glycyrrhiza echinata).* (*Footnote. I. acantho carpa, Lindley manuscripts; caule herbaceo erecto ramisque angulatis scabriusculis, foliis pinnatis 5-jugis viscido-pubescentibus; foliolis lineari-lanceolatis mucronulatis margine scabris, racemis folio aequalibus, leguminibus subrotundo-ovalibus compressis mucronatis echinatis monospermis.) March 29. Our next point was Mount Cunningham (Beery birree of the natives) and we travelled towards it along the margin of Field's Plains as the angles of the river allowed. CRACKS IN THE SURFACE. This was our straightest course, but we had to keep along the riverbank for another reason. The plains were full of deep cracks and holes so that the cart wheels more than once sunk into them, and thus detained us for nearly an hour. A sagacious black advised us to keep near the riverbank, and we found the ground better. We encamped at half-past two o'clock, after a journey of ten miles; and I immediately set out, accompanied by a native and a man carrying my theodolite, both on horseback, for the highest or northern point of Mount Cunningham (a). The distance was full five miles; yet we could not proceed direct on horseback, the scorched plains being full of deep, wide cracks; and we were therefore compelled to take a circuitous route nearer the river. ASCEND MOUNT CUNNINGHAM. There our guide called up three savage-looking natives with spears, whom he described to be the natives of the hill, and they accompanied us to the top. With some difficulty we led our horses near the crest, our new friends always keeping the vantage ground of us, apparently from apprehension. At length I planted my theodolite on the highest part of the summit which commanded a fine view of the western horizon; and from the mouths of my sable guides I obtained the native names, in all their purity, of the various hills in sight. The most distant, named Bolloon, were said to be near the great lake Cudjallagong--no doubt Regent's Lake of Oxley--and a peak they called Tolga I took to be Hurd's Peak of the same traveller.
