Lesson 69: Cotton is King

     Since the southern soil was good for planting and cotton was one of the most valuable crops grown, it became the main source of income for the plantations. 

 Since cotton took a long time to harvest and separate from it's seeds, Eli Whitney invented the cotton gin ("gin" was short for engine)  it could separate cotton much fast than one man at a time.

 Cotton became harvested, processed, and sold very much over the next ten years.
