The Economics of Cotton

KING COTTON

Almost no cotton was grown in the United States in 1787, the year the federal constitution was written. However, following the War of 1812, a huge increase in production resulted in the so-called cotton boom, and by midcentury, cotton became the key cash crop (a crop grown to sell rather than for the farmer’s sole use) of the southern economy and the most important American commodity. By 1850, of the 3.2 million slaves in the country’s fifteen slave states, 1.8 million were producing cotton; by 1860, slave labor was producing over two billion pounds of cotton per year. Indeed, American cotton soon made up two-thirds of the global supply, and production continued to soar. By the time of the Civil War, South Carolina politician James Hammond confidently proclaimed that the North could never threaten the South because “cotton is king.”

The crop grown in the South was a hybrid: Gossypium barbadense, known as Petit Gulf cotton, a mix of Mexican, Georgia, and Siamese strains. Petit Gulf cotton grew extremely well in different soils and climates. It dominated cotton production in the Mississippi River Valley—home of the new slave states of Louisiana, Mississippi, Arkansas, Tennessee, Kentucky, and Missouri—as well as in other states like Texas. Whenever new slave states entered the Union, white slaveholders sent armies of slaves to clear the land in order to grow and pick the lucrative crop. The phrase “to be sold down the river,” used by Harriet Beecher Stowe in her 1852 novel Uncle Tom’s Cabin, refers to this forced migration from the upper southern states to the Deep South, lower on the Mississippi, to grow cotton.

The slaves who built this cotton kingdom with their labor started by clearing the land. Although the Jeffersonian vision of the settlement of new U.S. territories entailed white yeoman farmers single-handedly carving out small independent farms, the reality proved quite different. Entire old-growth forests and cypress swamps fell to the axe as slaves labored to strip the vegetation to make way for cotton. With the land cleared, slaves readied the earth by plowing and planting. To ambitious white planters, the extent of new land available for cotton production seemed almost limitless, and many planters simply leapfrogged from one area to the next, abandoning their fields every ten to fifteen years after the soil became exhausted. Theirs was a world of mobility and restlessness, a constant search for the next area to grow the valuable crop. Slaves composed the vanguard of this American expansion to the West.

Cotton planting took place in March and April, when slaves planted seeds in rows around three to five feet apart. Over the next several months, from April to August, they carefully tended the plants. Weeding the cotton rows took significant energy and time. In August, after the cotton plants had flowered and the flowers had begun to give way to cotton bolls (the seed-bearing capsule that contains the cotton fiber), all the plantation’s slaves—men, women, and children—worked together to pick the crop (Figure). On each day of cotton picking, slaves went to the fields with sacks, which they would fill as many times as they could. The effort was laborious, and a white “driver” employed the lash to make slaves work as quickly as possible.

In the late nineteenth century, J. N. Wilson captured this image of harvest time at a southern plantation. While the workers in this photograph are not slave laborers, the process of cotton harvesting shown here had changed little from antebellum times.

Cotton planters projected the amount of cotton they could harvest based on the number of slaves under their control. In general, planters expected a good “hand,” or slave, to work ten acres of land and pick two hundred pounds of cotton a day. An overseer or master measured each individual slave’s daily yield. Great pressure existed to meet the expected daily amount, and some masters whipped slaves who picked less than expected.

Cotton picking occurred as many as seven times a season as the plant grew and continued to produce bolls through the fall and early winter. During the picking season, slaves worked from sunrise to sunset with a ten-minute break at lunch; many slaveholders tended to give them little to eat, since spending on food would cut into their profits. Other slaveholders knew that feeding slaves could increase productivity and therefore provided what they thought would help ensure a profitable crop. The slaves’ day didn’t end after they picked the cotton; once they had brought it to the gin house to be weighed, they then had to care for the animals and perform other chores. Indeed, slaves often maintained their own gardens and livestock, which they tended after working the cotton fields, in order to supplement their supply of food.

Sometimes the cotton was dried before it was ginned (put through the process of separating the seeds from the cotton fiber). The cotton gin allowed a slave to remove the seeds from fifty pounds of cotton a day, compared to one pound if done by hand. After the seeds had been removed, the cotton was pressed into bales. These bales, weighing about four hundred to five hundred pounds, were wrapped in burlap cloth and sent down the Mississippi River.

As the cotton industry boomed in the South, the Mississippi River quickly became the essential water highway in the United States. Steamboats, a crucial part of the transportation revolution thanks to their enormous freight-carrying capacity and ability to navigate shallow waterways, became a defining component of the cotton kingdom. Steamboats also illustrated the class and social distinctions of the antebellum age. While the decks carried precious cargo, ornate rooms graced the interior. In these spaces, whites socialized in the ship’s saloons and dining halls while black slaves served them (Figure).

An illustration depicts a large, luxurious room on the interior of a steamship. The ceilings are adorned with ornate molding and a chandelier, and the floor is covered with colorful carpet. Several well-dressed men, as well as a woman and a child, stroll about. Two men procure drinks from a bartender, and a formal dining table staffed by servants is visible in the distance.
As in this depiction of the saloon of the Mississippi River steamboat Princess, elegant and luxurious rooms often occupied the interiors of antebellum steamships, whose decks were filled with cargo.

Investors poured huge sums into steamships. In 1817, only seventeen plied the waters of western rivers, but by 1837, there were over seven hundred steamships in operation. Major new ports developed at St. Louis, Missouri; Memphis, Tennessee; and other locations. By 1860, some thirty-five hundred vessels were steaming in and out of New Orleans, carrying an annual cargo made up primarily of cotton that amounted to $220 million worth of goods (approximately $6.5 billion in 2014 dollars).

New Orleans had been part of the French empire before the United States purchased it, along with the rest of the Louisiana Territory, in 1803. In the first half of the nineteenth century, it rose in prominence and importance largely because of the cotton boom, steam-powered river traffic, and its strategic position near the mouth of the Mississippi River. Steamboats moved down the river transporting cotton grown on plantations along the river and throughout the South to the port at New Orleans. From there, the bulk of American cotton went to Liverpool, England, where it was sold to British manufacturers who ran the cotton mills in Manchester and elsewhere. This lucrative international trade brought new wealth and new residents to the city. By 1840, New Orleans alone had 12 percent of the nation’s total banking capital, and visitors often commented on the great cultural diversity of the city. In 1835, Joseph Holt Ingraham wrote: “Truly does New-Orleans represent every other city and nation upon earth. I know of none where is congregated so great a variety of the human species.” Slaves, cotton, and the steamship transformed the city from a relatively isolated corner of North America in the eighteenth century to a thriving metropolis that rivaled New York in importance (Figure).
