"In England the name 'Sheffield' has long been
synonymous with fine-quality steel, no more so than
in the early nineteenth century when the town, though
seeming to possess few advantages for the
manufacture of steel, virtually monopolized the
industry in Europe.
In contrast, the United States before 1860 was still
in the age of wood and iron, relying almost
exclusively on England for supplies of cast steel.
No better example illustrates the Anglo-American
relationship termed the Atlantic economy."
