"This report details an archaeological testing and mitigation effort conducted by Soil Systems Inc. at six historic sites in Berkeley County, South Carolina. The purpose of the project was to assess the significance of the sites and to mitigate the construction impacts of the U.S. Army Corps of Engineers' Cooper River Rediversion Canal Project. Five sites were tested during spring 1979. Three of these sites and an additional site recommended by Interagency Archeological Services-Atlanta were subjected to intensive data recovery during the summer and fall of 1979. Twenty-nine structures and many associated features were examined at two eighteenth century plantations. Historical research produced evidence sufficient to characterize their slave occupations. The results of this research included extensive archaeological and historical data shedding light on eighteenth century African slaves. The conclusions offer new insights into the institution of slavery and offer a basis for future research."--Abstract, page i.
