MR. EDITOR: - I have for some years past been a close observer of the facilities of the western part of our Island, for manufacturing brick and pottery, in their various branches. I am fully satisfied that the manufacture of clays, in various ways, can be carried on in that place, at a far greater profit, than else­where. The truth is, that in this section of our island, are found nearly all the varieties of the clays, and are of as good a quality, most of it, much superior to any that can be found within the limits of our state.
