Northern manufacturing extended the use of power-driven machines to a wider range of commodities in the middle decades of the century. By 1860, the United States was second only to Great Britain and France in manufacturing. Stationary steam engines powering advanced machinery allowed factories to set up in the nation’s largest cities (1999.396).
