And to the eastward of Mount Lennard, is elevated end mountainous, but bears a promising appearance having some considerable valleys at the base of the hills, which are probably well supplied with water. Towards the south end of the mountains, between the Collie and Preston, upon which his Excellency, the Lieutenant-Governor, has been pleased to bestow the name of "Roe's Range", the country becomes more sandy, and where the surface is not interrupted by the protusion of the granite formation of the range, it is partially covered with loose fragments of quartz and quartz rock. This description of country seems to prevail in those parts of the range which are exposed to the southerly winds.
The district of the Preston is not so fertile as that of the Collie, nor is it so considerable in point of size or inland navigation; but no soil can be finer than that on its banks, and the country through which it winds from the S.E. is more uniform and easy of access. The explorations which took place were not so extensive: regarding them it is only necessary to state the general result. There appear to be three rivers in the district, on the banks of which there is generally excellent alluvial soil. The southernmost river, which is named the 'Preston,' is navigable for the largest boats about five miles from its mouth, and is at that point a running stream of good water. Its banks are rich in soil and timber, but the former of these becomes sandy on receding from the river side.
The middle river, the 'Collie,' is navigable for ten or twelve miles, nearly up to the foot of the hills; the soil on its banks is not very good for three miles from its entrance, but it is there joined by a river flowing from the north, and the country,
