EISENERZE. Allgemeines. „The immense deposits of magnetite, spe- cular, and other ores, wich are found in the United States, and the facilities wich our mode of transportation gives to their Union with the great coal areas of the Alleghany and the Missis sippi, must give to the United States the fore- most position in the future iron industry, and consequently of the manufactures of the world.” (Henry Newton in „Transactions of the American Institute of Mining Engineers”. Vol. III, pag. 381.)
