So there are two varieties of the process—the acid Bessemer and the basic Bessemer, but the former, only, is used in this country as we have few high phosphorus ores. The analogous open-hearth processes, which are next to be described, are both used in this country with the basic open-hearth greatly in the lead. However, the basic Bessemer process of Thomas and Gilchrist is credited with making Germany’s great industrial development possible. ════╤════════════════════════════════════╦═══════════════════════════════════ Year│ TABLE NO. 1 ║ TABLE NO. 2 │ Materials Used for Rails[6] ║ Total Steel Made by Processes[6] ────┼──────────┬────────────┬────────────╫─────────────┬────────────┬──────── │ Wrought │ Bessemer │Open-Hearth ║ Bessemer │Open-Hearth │Crucible │ Iron │ Steel │ Steel ║ Steel │ Steel │ Steel ────┼──────────┼────────────┼────────────╫─────────────┼────────────┼──────── 1849│ =21,710=│ │ ║ │ │ 1850│ =39,360=│ │ ║ │ │ 1855│ =124,000=│ │ ║ │ │ 1860│ =183,000=│ │ ║ │ │ No Data 1865│ =318,000=│ │ ║ │ │ 1867│ =410,000=│ 2,280│ ║ =2,679=│ │ 1868│ =445,970=│ 6,450│ ║ =7,589=│ │ 1869│ =521,370=│ 8,620│ ║ =10,714=│ 893│ 1870│ =523,000=│ 30,360│ ║ =37,500=│ 1,339│ 1875│=448,000=↘│ 260,000│ ║ =335,000=│ 8,080│ 35,180 1880│ 441,000│ ↘=852,000=│ 12,160║ =1,074,000=│ 110,850│ 64,660 1885│ 13,000│ =959,000=│ 4,280║ =1,515,000=│ 133,000│ 57,600 1890│ 14,000│ =1,868,000=│ 3,590║ =3,689,000=│ 513,000│ 71,200 1895│ 5,810│ =1,300,000=│ 700║ =4,909,000=│ 1,137,000│ 68,700 1900│ 695│ =2,384,000=│ 1,330║ =6,685,000=│ 3,398,000│ 100,500 1905│ 318│ =3,192,000=│ 183,000║ =10,941,000=│ 8,971,000│ 102,200 1906│ 15│ =3,391,000=│ 186,000║ =12,276,000=│ 10,980,000│ 127,500 1907│ 925│ =3,380,000=│ 253,000║=11,668,000=↘│ 11,550,000│ 131,000 1908│ 71│ =1,349,000=│ 572,000║ 6,117,000│↘=7,837,000=│ 63,600 1909│ │ =1,767,000=│ 1,257,000║ 9,331,000│=14,494,000=│ 107,400 1910│ 230│=1,884,000=↘│ 1,751,000║ 9,413,000│=16,505,000=│ 122,300 1912│ │ 1,100,000│↘=2,105,000=║ 10,328,000│=20,780,000=│ 121,500 1913│ │ 818,000│ =2,528,000=║ 9,546,000│=21,600,000=│ 121,200 1914│ │ 324,000│ =1,526,000=║ 6,221,000│=17,175,000=│ 89,900 1915│ │ 327,000│ =1,775,000=║ 8,287,000│=23,679,000=│ 113,800 1916│ │ 440,000│ =2,270,000=║ 11,059,000│=31,415,000=│ 129,700
