The limestones, marbles, and marls have been described in previous reports of the State Survey, the first two mainly from the standpoint of building stone resources, and the last from that of general geology and agriculture. As economic resources, these materials have never become of very great importance, but the growing industrial importance of limestone and lime in the United States have made it desirable to bring the information on the State's resources up to date and render it readily available for future as well as present enterprises.
