“ The Industrial and Commercial Revolution.—On top of the radical changes in agriculture came an industrial and commercial revolution. The South had long been rich in natural resources, but the slave system had been unfavorable to their development. Rivers that would have turned millions of spindles tumbled unheeded to the seas. Coal and iron beds lay unopened. Timber was largely sacrificed in clearing lands for planting, or fell to earth in decay. Southern enterprise was consumed in planting. Slavery kept out the white immigrants who might have supplied the skilled labor for industry. ”
