Before venturing on so large a work I had employed Mr. Lennox on a smaller bridge in the new pass in the ascent to the Blue Mountains, and the manner in which he completed that work was such as to justify the confidence with which I suggested to the government this larger undertaking. ARRIVE AT SYDNEY. At length I arrived at Sydney and had the happiness on terminating this long journey to find that all the members of my family were well, although they had been much alarmed by reports of my death and the destruction of my party by the savage natives of the interior. ... GENERAL REMARKS ON THE CHARACTER OF THE SETTLED COUNTRY. Released from the necessity for recording each day's proceedings I may now add a few general remarks on the character of the country traversed in these various expeditions. FIRES IN THE WOODS. It has been observed that the soil in New South Wales is good only where trap, limestone, or granite rocks occur. Sandstone however predominates so much as to cover about six-sevenths of the whole surface comprised within the boundaries of nineteen counties. Wherever this is the surface rock little besides barren sand is found in the place of soil. Deciduous vegetation scarcely exists there, no vegetable soil is formed for, the trees and shrubs being very inflammable, conflagrations take place so frequently and extensively in the woods during summer as to leave very little vegetable matter to return to earth. On the highest mountains and in places the most remote and desolate I have always found on every dead trunk on the ground, and living tree of any magnitude also, the marks of fire; and thus it appeared that these annual conflagrations extend to every place. In the regions of sandstone the territory is, in short, good for nothing, and is besides very generally inaccessible, thus presenting a formidable obstruction to any communication between isolated spots of a better description. Land near Sydney has always been preferred to that which is remote, though the quality may have been equal; yet throughout the wide extent of twenty-three millions of acres only about 4,400,000 have been found worth 5 shillings per acre, and the owners of this appropriated land within the limits have been obliged to send their cattle beyond them for the sake of pasturage.
