We will rather extend our enquiries to those parts of the colony upon which we shall not be called upon to remark in the succeeding pages.
Returning to the coast, we may mark the geological changes in a line to the S.W.of Sydney; and as my object is to extend the information of my readers, I shall notice any particular district on either side of the line I propose to touch upon, which may be worthy of notice.

It would appear that the first decided break in the sandstone formation which penetrates into the county of Camden, is at Mittagong Range.

It is there traversed by a dike of whinstone, of which that range is wholly composed.

The change of soil and of vegetation are equally remarkable at this place; the one being a rich, greasy, chocolate-coloured earth, the other partaking greatly of the intertropical character.

In wandering over them, I noticed the wild fig and the cherry-tree, growing to a much larger size than I had seen them in any other part of the colony.
