Being now close under the mountain, we dismounted and sent our horses back for the sake of food to the bank of the last-mentioned river. The first part of our ascent, on foot, was extremely steep and laborious, although it was along the most favourable feature I could find. Above it the impediments likely to obstruct our further ascent were two high and perpendicular rocky cliffs; but I had observed before ascending those crevices and intervals between rocks where we might most easily effect an ascent; and through these we accordingly penetrated without much difficulty. The upper precipice consisted of cliffs about 140 feet in perpendicular height. Fortunately the ablest of the men with me was a house carpenter and, being accustomed to climb roofs, he managed to get up and then assist the rest. CLOUDS COVER IT. Having gained the top of this second precipice, we found winter and desolation under drizzling clouds which afforded but partial and transient glimpses of the world below. The surface at the summit of the cliffs was broad and consisted of large blocks of sandstone, separated by wide fissures full of dwarf bushes of banksia and casuarinae. These rocks were inclined but slightly towards the north-west and, the bushes being also wet and curiously encrusted with heavy icicles, it was by no means a pleasant part of our journey to travel nearly half a mile upwards, either on the slippery rock or between fissures among wet bushes. At length however we reached the highest point and found that it consisted of naked sandstone. The top block was encrusted with icicles, and had become hoary under the beating of innumerable storms. At the very summit I found a small heath-like bushy Leucopogon, from six inches to a foot high. It was in flower although covered with ice.* Also a variety of Leucopogon villosus, with rather less hair than usual, and another species of the same genus, probably new. Near the highest parts of the plateau I found a new species of eucalyptus with short broad viscid leaves, and rough-warted branches.** (*Footnote.
