By far the most important United States export product in the eighteenth and nineteenth centuries was cotton, favored by the European textile industry over flax or wool because it was easy to process and soft to tile touch. Mechanization of spinning and weaving allowed significant centralization and expansion in the textile industry during this period, and at the same time the demand for cotton increased dramatically. American producers were able to meet this demand largely because of tile invention of the cotton gin by Eli Whitney in 1793. Cotton could be grown throughout the South, but separating the fiber — or lint — from the seed was a laborious process. Sea island cotton was relatively easy to process by hand, because its fibers were long and seeds were concentrated at the base of the flower, but it demanded a long growing season, available only along the nation's eastern seacoast. Short-staple cotton required a much shorter growing season, but the shortness of the fibers and their mixture with seeds meant that a worker could hand-process only about one pound per day. Whitney's gin was a hand-powered machine with revolving drums and metal teeth to pull cotton fibers away from seeds. Using the gin, a worker could produce up to 50 pounds of lint a day. The later development of larger gins, powered by horses, water, or steam, multiplied productivity further.
The interaction of improved processing and high demand led to the rapid spread of the cultivation of cotton and to a surge in production. It became the main American export, dwarfing all others. In 1802, cotton composed 14 percent of total American exports by value. Cotton had a 36 percent share by 1810 and over a 50 percent share in 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 American exports in that year. Clearly, cotton was king in the trade of the young republic. The growing market for cotton and other American agricultural products led to an unprecedented expansion of agricultural settlement, mostly in the eastern half of the United States — west of the Appalachian Mountains and east of the Mississippi River.

附：托福阅读理解做题的误区
考生做旧托福考试(TOEFL)阅读或者平时的阅读练习时，时常表现出一些不良的做题习惯。有些考生读文章时喜欢在试题上划线，似乎不做记号，阅读就无法进行，思维就停止活动。不过在新托福网络考试中，考生面对电脑就做不了任何标志记号。
有些考生文章根本不读完，直接做题。这种方法相当于瞎子摸象，对文章只有局部的感觉，整个文章的概念无法获得。要提醒考生的是，近年考试中针对整个文章提问的题量有所增加。所以，这种不看文章直接做题的方法是极其危险的。
有些考生则喜欢把文章一字不漏地细读之后再做题。这种方法仅适合于两种情况，其一，考生已具备相当的阅读水平，长期以来运用这种方法效果甚佳;其二，某一篇具体的文章是考生所熟悉的内容，细读文章并不会花太多的时间。一般来说，大部分考生采用细读文章方法，做题时间严重不足。考生不应该忘记，阅读理解测试速度和理解两个方面。
在做词汇题时，许多考生认为做不对题与自己的词汇量有关，认识单词能做对，不认识单词就会做错。事实上，那些认识的单词经常做错，不认识的单词反而能做对。原因是，做不认识单词时，考生会仔细研读词汇题的上下文，力求在上下文中突破。而做认识单词时，忽略上下文的重要性，往往是装模作样的看一下上下文，便匆匆做出抉择。所以，做好词汇题关键在于透彻分析上下文--词汇题的句子以及上下一句话，有时候，个别词汇题也许需要在文章其他段落寻找线索。
