Excerpt from A Treatise on Steel: Comprising Its Theory, Metallurgy, Properties, Practical Working, and Use; With an Appendix on the Bessemer and the Martin Processes for Manufacturing Steel, From the Report of Abram S. Hewitt, United States Commissioner to the Universal Exposition

Not many years ago, when the uses of steel were confined to the manufacture of tools, cutting instrument's, etc., there were few quali ties of steel; and cast steel, tilted steel, and some German steels especially employed for the manufacture of files, scythes, etc., were the only compounds of iron and carbon known under the name of steel.

The enormous progress made recently in iron metallurgy and in metallic constructions, has prompted the employment in large quan tities of new kinds of steel, endowed with properties of resistance and flexibility hitherto unknown and unsuspected, and at a cheapness of cost which has allowed their use for rails, large pieces of machinery, railroad tires, plates for boilers, ships, bridges, etc.
