Fish remains have been found inthe carbonate No economic use has been made of the Marcellus shale in thisvicinity. It contains possibilities in the source of material for themanufacture of brick and tile, but as yet no attempt has been madeto so utilize Considerable money and energy have been wastedin digging in this shale in different places in search of coal. Thesimilarity in color and structure of this shale to that usually ac-companying coal beds is doubtless the cause of this ancient butvain search for coal.
