Clear, orderly coverage of cotton culture in Alabama, the Delta, California, with emphasis on the effects of mechanization in each area; of ginning, grading, marketing and manufacture generally. Also noted are the contributions of science, especially in breeding, and the increasing use of cottonseed in any array of products. Although brief mention is made of cotton-growing elsewhere and earlier, the focus is on the U.S. now-and current relevance as well as the many supporting photos and maps makes this superior to the old First Book of Cotton.
