19TH JULY.--With the intention to lose no opportunity of getting further to the westward, I travelled on towards the base of the most northern summit of the range in the west; but I was, at length, so shut up by gullies and scrubby extremities near its base and all radiating from it, and becoming very deep, that I took the party aside into a grassy ravine near, where I directed the men to encamp, and hastened myself to the summit. From it, the view westward was not so extensive as I expected. Something like precipitous slopes to some channel or water-course, apparently falling either S. W. or N. E., formed the most promising feature; but, although my object was to have travelled in that direction, the scrub seemed too thick to admit of a passage. Open forest land appeared to the N. E., and there, the gently undulating features, although much lower than the range on whose northern extremity I then stood, seemed nevertheless to form a connection between it and some higher ranges of open forest land, that appeared between me and the coast. Through one wide opening in these, about east, I saw some broken hills, at a very great distance, say seventy or eighty miles. The ridgy- connected undulations formed the heads of some valleys sloping to the south-east, whereof the waters would evidently join those of the Balmy Creek, while others, rising on the north-west side, seemed to belong to a separate basin, and to form a river falling to the north-west. This river was indicated only by slopes meeting and interlacing in a valley. To the left or westward of that supposed river channel, a mighty isolated mountain mass shut out any view of the further course of the water of the valley formed between it and these slopes; but, as the very lowest point of the whole horizon, as indicated by the spirit-level of the theodolite, lay in that direction, I determined to pursue that bearing, (10 deg. W. of N.) through the open forest country that intervened. I found that the mountain commanding this view, was elevated 2247 feet above the sea, according to the Syphon barometer, and in using this instrument, I could not forget Colonel Mudge, who had kindly taught me its use; I therefore named that summit Mount Mudge. In the gravel at the base of the hill, were water-worn pebbles of trap and basalt. The rock of which the range itself consisted, seemed to be a calcareous grit, with vegetable impressions, apparently of GLOSSOPTERIS BROWNII. On descending to the camp, I was informed that the cattle-watering party came suddenly upon two natives, one of whom was a placid old man, the other middle-aged. Corporal Graham did all he could to allay their fears, and convince them that they were in no danger from such strangers. The elder at length handed his little bundle to the younger and sat down, on seeing the Corporal's green bough; meanwhile the other walked on. When Graham took the old man's hand, and shook it, also patting him on the back, and
