NLNI.NO. The most extensively utilized of the State's diversified geological resources are its clays. New Jersey ranks second in the produc tion of pottery and third in the total output of clay products. Brick clay is found in most parts of the State. The value of the pottery products and of the combined output of brick and tile, re spectively, ranges between $3,000,000 and $9,000, 000 annually. (See Manufactures below.) Morris County furnishes infusorial earths used in the manufacture of dynamite and giant powder, and for polishing purposes. Deposits of marl found in the State are utilized for fertilizers. A Va riety of stone is quarried in the northwestern count ies, and constitutes another important source of wealth. The production of granite has increased rapidly since 1896. The output for 1900 was appraised at $1.170,555, or five times the value of the product in the former year. The value of the sandstone quarried in 1900 was $198,234, but the annual yield is usually worth much more. New Jersey ranks second in the production of Portland cement. Iron was mined in Warren County early in the history of the State. and has been mined contiuuousl• in the northwestern part until the present time. The
entire product in 1900 was of the magnetite variety, estimated at 344,247 long tons. The iron is mined with greater difficulty than in the larger iron-producing regions, but the saving of the cost of transportation makes it profitable. The New .Jersey ores have a larger per ton value I $3.18 in 1899) than those obtained in any other State.
FtsnEntEs. New Jersey, with its long and well indented coast line, and bounded by the Hudson and the Delaware, is well adapted for the de velopment. of an extensive fishery industry. in whieh seventeen out of the twe»ty-one counties of the State participate directly. There were 12.270 persons so engaged in 1898, as against 16.539 in 1891. The value of the product for 1898 was $3.563,766, only about $44.000 more than the product of 1891. The catch of in the same was valued at $1.670.000. Next to oysters, the principal species with respect to value are (dams, shad, squeteague, bluefish, and cod. The value of caviar in 1898 was $79,693. The menhaden industry in that year was rep resented by six factories, and yielded a product of $57,993.
