We here quitted the boat to enter a deep and picturesque ravine, of which the mean breadth was only one hundred and forty-seven feet, bounded on each side by perpendicular cliffs from one hundred and fifty to two hundred feet high; in the centre ran a clear stream, sometimes forming deep and extensive pools, sometimes divided into innumerable little rills which gurgled along through a dense and matted vegetation; and bordered on each side of the main bed by a lofty species of Eucalyptus, with a bark resembling layers of coarse white paper, and a foliage pendant and graceful; whilst the great height of these trees for they raised their heads above the cliffs, contrasted strangely with the narrowness of the ravine in which they grew. The space between these trees and the cliffs was filled by a dense forest, principally composed of the Pandanus and wild nutmeg trees. Rich grasses and climbing plants occupied the interval and twined around the trees, whilst parakeets of the most vivid colours filled the wood with their cries. Nothing could be more striking than this singular and novel scene; and we were all delighted as we wound our way up the beautiful ravine. The same character continued for the next mile or two, whilst occasionally branch valleys of similar character ran off from a main one, giving it at these points a much greater width. The summit of the cliffs was found to be generally a rocky sandy tableland, thinly wooded; and from what I had seen it appeared to me that I was not likely to find a place better adapted for landing the stores than the main ravine. On embarking to return we could perceive no sign of One Tree Island; and as we swept down towards the sea the leafy top of a tree seen in the clear water under the boat was the only evidence of its existence; though a few hours ago it had formed so prominent an object. FATE OF TWO OF THE DOGS. The long-boat returned to the vessel half an hour after us and brought eighty gallons of water; but the spot whence it was obtained had been found very inconvenient for the purpose. At the waterhole they had met Ranger, the dog we lost the first day; but he appeared quite mad, and without recognising any of them ran wildly away into the woods. The body of poor Ringhalz was also found, who had died on the spot where he fell. LABOUR OF DISEMBARKING STORES. December 6.
