With extensive iron deposits, especially in the western counties, Virginia was a pioneer in the iron industry. The first ironworks in the new world was established at Falling Creek in 1619, though it was destroyed in 1622. There would eventually grow to be 80 ironworks, charcoal furnaces and forges with 7,000 hands at any one time, about 70 percent of them slaves. Ironmasters hired slaves from local slave owners because they were cheaper than white workers, easier to control, and could not switch to a better employer. But the work ethic was weak, because the wages went to the owner, not to the workers, who were forced to work hard, were poorly fed and clothed, and were separated from their families. Virginia's industry increasingly fell behind Pennsylvania, New Jersey and Ohio, which relied on free labor. Bradford (1959) recounts the many complaints about slave laborers and argues the over-reliance on slaves contributed to the failure of the iron-masters to adopt improved methods of production for fear the slaves would sabotage them. Most of the blacks were unskilled manual laborers, although Lewis (1977) reports that some were in skilled positions.
