Despite such limitations, this study is a detailed examination of a segment of colonial Virginia's plantation culture. It has been prepared with the hope that it will provide Dr. Darter with essential material for his area studies and, also, with the wider objective of increasing the knowledge of the material culture of colonial America. Appropriate to the function of a museum such as the Smithsonian, this study is concerned principally with what is concrete--objects and artifacts and the meanings that are to be derived from them. It has relied upon the mutually dependent techniques of archeologist and cultural historian and will serve, it is hoped, as a guide to further investigations of this sort by historical museums and organizations. Among the many individuals contributing to this study, I am especially indebted to Dr. Darter; to the members of the American Philosophical Society who made the excavations possible; to Dr. Stewart, who reviewed the archeological sections at each step as they were written; to Mrs. Sigrid Hull who drew the line-and-stipple illustrations which embellish the report; Edward G. Schumacher of the Bureau of American Ethnology, who made the archeological maps and drawings; Jack Scott of the Smithsonian photographic laboratory, who photographed the artifacts; and George Harrison Sanford King of Fredericksburg, from whom the necessary documentation for the 18th-century courthouse site was obtained. I am grateful also to Dr. Anthony N. B. Garvan, professor of American civilization at the University of Pennsylvania and former head curator of the Smithsonian Institution's department of civil history, for invaluable encouragement and advice; and to Worth Bailey formerly with the Historic American Buildings Survey, for many ideas, suggestions, and important identifications of craftsmen listed in Mercer's ledgers. I am equally indebted to Ivor Noël Hume, director of archeology at Colonial Williamsburg and an honorary research associate of the Smithsonian Institution, for his assistance in the identification of artifacts; to Mrs. Mabel Niemeyer, librarian of the Bucks County Historical Society, for her cooperation in making the Mercer ledgers available for this report; to Donald E. Roy, librarian of the Darlington Library, University of Pittsburgh, for providing the invaluable clue that directed me to the ledgers; to the staffs of the Virginia State Library and the Alexandria Library for repeated courtesies and cooperation; and to Miss Rodris Roth, associate curator of cultural history at the Smithsonian, for detecting Thomas Oliver's inventory of Marlborough in a least suspected source. I greatly appreciate receiving generous permissions from the University of Pittsburgh Press to quote extensively from the _George Mercer Papers Relating to the Ohio Company of Virginia_, and from Russell & Russell to copy Thomas Oliver's inventory of Marlborough.
