22、, favored by the European textile industry over flax orwool because it was easy to process and soft to tile touch. Mechanization of spinningLine and weaving allowed significant centralization and expansion in the textile industry during5 this period, and at the same time the demand for cotton increa

23、sed dramatically. Americanproducers were able to meet this demand largely because of tile invention of the cotton ginby Eli Whitney in 1793. Cotton could be grown throughout the South, but separating thefiber-or lint-from the seed was a laborious process. Sea island cotton was relativelyeasy to proc

24、ess by hand, because its fibers were long and seeds were concentrated at the10 base of the flower, but it demanded a long growing season, available only along thenations eastern seacoast. Short-staple cotton required a much shorter growing season,but the shortness of the fibers and their mixture wit

25、h seeds meant that a worker couldhand-process only about one pound per day. Whitneys gin was a hand-powered machinewith revolving drums and metal teeth to pull cotton fibers away from seeds. Using the gin,15 a worker could produce up to 50 pounds of lint a day. The later development of largergins, p

26、owered by horses, water, or steam, multiplied productivity further.The interaction of improved processing and high demand led to the rapid spread ofthe cultivation of cotton and to a surge in production. It became the main Americanexport, dwarfing all others. In 1802, cotton composed 14 percent of t

27、otal American20 exports by value. Cotton had a 36 percent share by 1810 and over a 50 percent sharein 1830. In 1860, 61 percent of the value of American exports was represented by cotton.In contrast, wheat and wheat flour composed only 6 percent of the value of Americanexports in that year. Clearly,
