The use of iron, however, could not be dispensed with. The very foundations of society rested upon an abundant supply of it, for tools and implements of peace, as well as for weapons of war. In the dearth of the article at home, a supply of it was therefore sought for abroad; and both iron and steel came to be imported in largely-increased quantities. This branch of trade was principally in the hands of the Steelyard Company of Foreign Merchants, established in Upper Thames Street, a little above London Bridge; and they imported large quantities of iron and steel from foreign countries, principally from Sweden, Germany, and Spain. The best iron came from Spain, though the Spaniards on their part coveted our English made cannons, which were better manufactured than theirs; while the best steel came from Germany and Sweden.* [footnote... As late as 1790, long after the monopoly of the foreign merchants had been abolished, Pennant says, "The present Steelyard is the great repository of imported iron, which furnishes our metropolis with that necessary material. The quantity of bars that fills the yards and warehouses of this quarter strikes with astonishment the most indifferent beholder."--PENNANT, Account of London, 309. ...]
