The cotton for which Whitney's machine accomplished so much, was the short staple, which is the principal product of the South. The Sea Island cotton could not be cleaned by it, on account of the length and delicacy of its fiber; and this species, for the want of some cheap and expeditious method of preparing it, has seldom been grown to a greater quantity than fifty thousand bags of three hundred pounds each. Consequently, it has always commanded a high price.
