“The old men,” as they are frequently called in the works, appear to have had an inkling of the real nature of the process: The rising impurities and combination of opposite gases indicated by bubbles were called the “Soldier’s coming.” At any rate the Bessemer invention is an adaptation of a principle acted upon during the past century in the Shropshire ironworks. Mr. Reynolds’s patent was obtained December 6, 1799, and was stated to be for “preparing iron for the conversion thereof into steel.” In his specification he described his invention to consist in the employment of oxide of manganese in the conversion of pig-iron into malleable iron or steel, but did not enter into details as to the method he employed for carrying his invention into effect. John Wilkinson obtained a patent January 23, 1801, for making “Pig or cast metal from ore, which when manufactured into bar-iron will be found equal in quality to any that is imported from Russia or Sweden.” The patentee states his invention to consist “in making use of manganese, or ores containing manganese, in addition to ironstone and other materials used in making iron, and in certain proportions, to be varied by the nature of such ironstone and other materials.” Mr. Reynolds was not only a chemist, but a geologist. He succeeded in forming a collection of carboniferous fossils to which modern professors acknowledge their obligations, and which, with the additions made by Mr. William Anstice, Dean Buckland pronounced one of the finest in Europe. Other manufacturers, every day dealing with subterranean treasures that give iron in abundance, were as dwellers amid the ruins of some ancient city, taking down structures of the builders of which and of the history of which they were ignorant. With him minerals had an interest beyond their market value. Coal and ore from the dusky mine, raised at so much per ton, were not minerals merely, but materials prepared to his hand by Nature. He detected traces of that venerable dame’s cast-off garments in one; the others were fabrics, the result of processes as varied as his own, the produce of machinery more wonderful and powerful than that he was about to employ in converting them to the general uses and purposes of mankind. His pit-shafts to him were mere inlets to the deep storehouse of the globe where Providence had treasured means whereby to enrich future inhabitants of the surface. Geology as a science, ’tis true, was but beginning to shed its light on the cosmogony of the world; endeavours to make out a connected history of the earth from examinations of the structure itself were deemed strange; and the more intelligent of his contemporaries, who without hesitation adopted speculations daring and beyond the province of human intellect, looked coldly upon his labours. The old workmen to whom he offered premiums for the best specimens could not for the life of them make out the meaning of his
