Manganese-ores of good quality are mined in quantity in Chili, Brazil, Japan, the Republic of Colombia, India and Turkey, and are exported. United States.--In 1899 the United States, the foremost pigiron producing country of the world, surpassed its former highest record, turning out 13,620,703 gross tons of pig-iron. To supply the raw material for this amount of iron, the ironore mines were actively wrought, and 24,683,173 gross tons were mined. Until 1893 the United States was practically a producer for the home market only; but in that year the exports of iron and steel exceeded in value the imports, and the difference has become annually more marked, until in 1899 the value of the iron and steel exports was $105,689,645, and that of the imports only $15,799,206. Most of the exports were manufactured products, thus securing a larger remuneration to producers than if they had been raw materials. The iron and steel exports of 1899 included steel rails, valued at $6,122,382; wire, $5,526,930; pig-iron, $3,282,241; plates and sheets, $2,047,301; wire nails and tacks, $1,955,773; castings, $1,348,133; and cut nails, $482,382. This position has been attained by the liberal use of mechanical and labor-saving devices, whereby the cost of handling the raw materials entering into the production of pig-iron, and of the metal itself, has been reduced to a minimum. In the winning of iron-ore and coal, electric-and compressedair drills, improved explosives, carefully designed timbering, and scientific methods of mining, hauling and raising the mineral won, have reduced the cost of these materials, placed on cars for...
