Object of investigation was to examine brick supply for every town of 1000 or more inhabitants and for every county in the state, to ascertain extent of various deposits now developed, to find new deposits, and to determine qualities of these deposits and of certain mixtures with a view to finding out whether it is possible to produce refractory wares, pottery, paving brick, and other high-grade products.
