PREFACE vii 



has contributed much constructive criticism, particularly in 

 regard to the form of this study. I owe a debt of gratitude to 

 Professor Lane Cooper of Cornell University, whose pioneer 

 articles on Bartram have proved invaluable to me, and who 

 generously sent me the bibliography to his sketch of Bartram 

 in the Dictionary of American Biography before its publication. 

 To the generosity of Mr. Henry Jones of New York, I owe 

 Bartram's hitherto unknown letter to his nephew. 



It is no less a pleasure to acknowledge the fine cooperation of 

 the many librarians upon whose kindness I have often presumed ; 

 in particular I wish to mention the librarians of the Pennsyl- 

 vania Historical Society, of the Bartram Memorial Library at 

 the University of Pennsylvania, of the American Philosophical 

 Society, of the Philadelphia Academy of Natural Sciences, of 

 the Genealogical Society of Pennsylvania, of the Maryland Dio- 

 cesan Library, and of The Johns Hopkins University Library.
