William Hiott and Patrick McMillan discuss the contributions made by African Americans. When Paul de St. Julien died in 1741, he owned forty-five slaves. Most of the profit which came from St. Julien’s plantation was rice, but they also grew cotton and raised cattle. Rice, namely “inland” rice was a cash crop; so successful that it made a huge impact on South Carolina’s natural history. Many of the swamps and marshes seen in the low country today are a result of these rice fields.
