At this distance, however, the aspect of the country begins rapidly to improve. The forest is less thick, and the trees in general are of another description; the iron barks, yellow gums, and forest oaks disappearing, and the stringy barks, blue gums, and box trees, generally usurping their stead. When you have advanced about four miles further into the interior, you are at length gratified with the appearance of a country truly beautiful. An endless variety of hill and dale, clothed in the most luxuriant herbage, and covered with bleating flocks and lowing herds, at length indicate that you are in regions fit to be inhabited by civilized man. The soil has no longer the stamp of barrenness. A rich loam resting on a substratum of fat red clay, several feet in depth, is found even on the tops of the highest hills, which in general do not yield in fertility to the vallies. The timber, strange as it may appear, is of inferior size, though still of the same nature, i. e. blue gum, box, and stringy bark. There is no underwood, and the number of trees upon an acre do not upon an average exceed thirty. They are, in fact, so thin, that a person may gallop without difficulty in every direction. Coursing the kangaroo is the favourite amusement of the colonists, who generally pursue this animal at full speed on horseback, and frequently manage, notwithstanding its extraordinary swiftness, to be up at the death; so trifling are the impediments occasioned by the forest. The above general description may be applied with tolerable accuracy, to the whole tract of country which lies between this space and the Nepean River. The plains, however, on the banks of this river, which are in many places of considerable extent, are of far greater fertility, being a rich vegetable mould, many feet in depth, and have without doubt, been gradually formed by depositions from it during the periods of its inundations. These plains gradually enlarge themselves until you arrive at the junction of the Nepean with the Hawkesbury, on each side of which they are commonly from a mile to a mile and a half in breadth. The banks of this latter river are of still greater fertility than the banks of the former, and may vie in this respect with the far-famed banks of the Nile. The same acre of land there has been known to produce in the course of one year, fifty bushels of wheat and a hundred of maize. The settlers have never any occasion for manure, since the slimy depositions from the river, effectually counteract the exhaustion that would otherwise be produced by incessant crops. The timber on the banks of these rivers is for the most part apple tree, which is very beautiful, and bears in its foliage and shape a striking resemblance to the oak of this country. Its wood, however, is of no value except for firing, and for the immense quantity of pot-ash which might be made from it. The blue gum and stringy bark are also very common on these flooded lands, and of the best description.
