At six o'clock the sky became clear, the clouds had indeed left the mountain and, as soon as it was day, I mounted the frozen rock. In the dawn however all lower objects were blended in one grey shade, like the dead colouring of a picture. I could distinguish only a pool of water, apparently near the foot of the mountain. This water I afterwards found to be a lake eight miles distant and in my map I have named it Lake Lonsdale, in honour of the Commandant then or soon after appointed at Port Phillip. I hastily levelled my theodolite but the scene, although sublime enough for the theme of a poet, was not at all suited to the more commonplace objects of a surveyor. The sun rose amid red and stormy clouds, and vast masses of a white vapour concealed from view both sea and land save where a few isolated hills were dimly visible. Towards the interior the horizon was clear and, during a short interval, I took what angles I could obtain. To the westward the view of the mountain ranges was truly grand. Southward or towards the sea I could at intervals perceive plains clear of timber and that the country was level, a circumstance of great importance to us; for I was apprehensive that between these mountains and the coast it might be broken by mountain gullies as it is in the settled colony and all along the Eastern coast. If such had proved to be the case the carts could not have been taken there; and I must have altered the plan of my intended route. Before I could observe the angles so desirable clouds again enveloped the mountain, and I was compelled to quit its summit without completing the work. The wind blew keenly, the thermometer stood as low as 27 degrees, and in the morning the rocks were more thickly encrusted with ice. DESCEND WITH DIFFICULTY. The difficulty of our descent under such circumstances was therefore increased but no impediment could have arrested us then, the lower regions having so many attractive charms for such cold and hungry beings. MEN TAKEN ILL. That night on the summit materially injured the health of two of my best men who had been with me on all three of my expeditions. Muirhead was seized with ague and Woods with a pulmonary complaint; and although both recovered in a few weeks they were never so strong afterwards. NEW PLANTS FOUND THERE. We found upon the mountain, besides those already mentioned, various interesting plants which we had seen nowhere else. Amongst them: A most beautiful downy-leaved Epacris with large, curved, purple flowers, allied to E. grandiflora but much handsomer.* (*Footnote. E. tomentosa, Lindley manuscripts; foliis ovatis acutis planis crassis tomentosis, floribus cernuis, corolla arcuata infundibulari laciniis obtusis apiculatis.) A most remarkable species of Phebalium* with holly-like leaves and bright red flowers resembling those of a Boronia. It was related to P. phylicifolium but quite distinct.
