Some Southerners effectively applied slave labor to the cultivation of corn, grain, and hemp (for making rope and twine), to mining and lumbering, to building canals and railroads, and even to the manufacture of textiles, iron, and other industrial products. Nevertheless, no other American region contained so many white farmers who merely subsisted on their own produce. The “typical” white Southerner was not a slaveholding planter but a small farmer who tried, often without success, to achieve both relative self-sufficiency and a steady income from marketable cash crops.
