BIBLIOGRAPHY. 



In the bibliography given below the attempt has been made to 

 give practically all the sources and secondary vi^orks important 

 for the subject covered in the preceding pages. All the main libra- 

 ries and accessible collections of New York, New Haven, Wash- 

 ington, Providence, Boston, and Salem, and to a certain extent, 

 Philadelphia, have been carefully examined. There may remain 

 some manuscript collections in Philadelphia and Baltimore which 

 would be of value, and there are undoubtedly valuable private 

 collection of papers, such as the personal papers of Elias H. 

 Derby, which for one reason or another have been inaccessible 

 or unknown to the author. It is not likely that any further dis- 

 coveries of material will greatly alter the conclusions reached, 

 however, except perhaps to expand the paragraphs on the history 

 of the merchant houses of New York, Philadelphia, and Balti- 

 more. 



In enumerating the sources and authorities used the attempt 

 has been made in most cases to indicate briefly the contents of 

 the book or document, as far as concerns the subject in hand, and 

 in some cases to state as well as can be done in a sentence, its 

 value and reliability. No elaborate critical notes have been 

 attempted, as they would have made the bibliography too bulky. 



In all cases the present location of the manuscript is given, 

 and in some cases, of the printed books. Most of the printed 

 sources and authorities are in the Yale University Library, the 

 Day (Missionary) Library of the Yale Divinity School, and 

 Prof. Frederick Wells Williams' private collection. With a few 

 exceptions it may be understood that unless the location of a 

 book is given, it will be found in one of these places.
