The Cotton Gin made a huge difference! Before cotton can be spun into thread, its seeds must be removed. The people of ancient India developed a two-roller device through which they would pull raw cotton to separate the seeds from long-staple cotton fibers. In 1788, Joseph Eve patented a machine that used rollers to clean seeds from Sea Island cotton. One person could clean 24-30 pounds each day. Sea Island cotton is a finicky plant that thrives only in a small strip of land 30-40 miles in coastal South Carolina, Georgia, and Florida (which was Spanish until 1823). It was impossible to grow enough in this confined area to meet world demand. Short-staple G. hirsutum cotton could be grown in non-coastal upland areas and was nicknamed Upland cotton. The sturdy plant was already growing over a wide geographical range, but it presented a different problem. Upland cotton was so difficult to clean that the roller gin (short for engine) could not be used to clean the cotton. Instead, it took o
