Mr. Swift and Dr. Eckenrode, in addition to reading early drafts of the manuscript, have read the last draft with particular care and I have utilized their criticisms. The proof has been read by Mr. Swift and the comment of this finished critic has been especially valuable.

I am indebted in the highest possible degree to Mr. Worthington C. Ford, of the Massachusetts Historical Society, who has generously aided me with his profound and extensive knowledge of manuscript sources and of the history of the times of which this work treats. His sympathetic interest and whole-hearted helpfulness have not only assisted me, but encouraged and sustained me in the prosecution of my labors.

In making these acknowledgments, I do not in the least shift to other shoulders the responsibility for anything in these volumes. That burden is mine alone.

I extend my thanks to Mr. A. P. C. Griffin, Assistant Librarian, and Mr. Gaillard Hunt, Chief of the Manuscripts Division, of the Library of Congress, who have been unsparing in their efforts to assist me with all the resources of that great library. The officers and their assistants of the Virginia State Library, the Boston Public Library, the Library of Harvard University, the Manuscripts Division of the New York Public Library, the Massachusetts Historical Society, the Pennsylvania Historical Society, and the Virginia Historical Society have been most gracious in affording me all the sources at their command.

I desire to express my appreciation for original material furnished me by several of the descendants and collateral relatives of John Marshall. Miss Emily Harvie, of Richmond, Virginia, placed at my disposal many letters of Marshall to his wife. For the use of the book in which Marshall kept his accounts and wrote notes of law lectures, I am indebted to Mrs. John K. Mason, of Richmond. A large number of original and unpublished letters of Marshall were furnished me by Mr. James M. Marshall, of Front Royal, Virginia, Mr. Robert Y. Conrad, of Winchester, Virginia; Mrs. Alexander H. Sands, of Richmond, Virginia; Miss Sallie Marshall, of Leeds, Virginia; Mrs. Claudia Jones, and Mrs. Fannie G. Campbell of Washington, D.C.; Judge J. K. M. Norton, of Alexandria, Virginia; Mr. A. Moore, Jr., of Berryville, Virginia; Dr. Samuel Eliot Morison, of Boston, Massachusetts, and Professor Charles William Dabney, of Cincinnati, Ohio. Complete copies of the highly valuable correspondence of Mrs. Edward Carrington were supplied by Mr. John B. Minor, of Richmond, Virginia, and by Mr. Carter H. FitzHugh, of Lake Forest, Illinois. Without the material thus generously opened to me, this narrative of Marshall's life would have been more incomplete than it is and many statements in it would, necessarily, have been based on unsupported tradition.

Among the many who have aided me, Judge James Keith, of Richmond, Virginia, until recently President of the Court of Appeals of Virginia; Judge J. K. M. Norton and the late Miss Nannie Burwell Norton of Alexandria, Virginia; Mr. William Marshall Bullitt, of Louisville, Kentucky; Mr. Thomas Marshall Smith, of Baltimore, Maryland; Mr. and Mrs. Alexander H. Sands; Mr. W. P. Taylor and Dr. H. Norton Mason, of Richmond, Virginia; Mr. Lucien Keith, Mr. William Horgan, and Mr. William C. Marshall, of Warrenton, Virginia; Judge Henry H. Downing and Mr. Aubrey G. Weaver, of Front Royal, Virginia, have rendered notable assistance in the gathering of data.

I am under particular obligations to Miss Emily Harvie for the use of the striking miniature of Marshall, the reproduction of which appears as the frontispiece to the first volume; to Mr. Roland Gray, of Boston, for the right to reproduce the portrait by Jarvis as the frontispiece of the second volume; to Mr. Douglas H. Thomas of Baltimore, Maryland, for photographs of the portraits of William Randolph, Mary Isham, and Mary Randolph Keith; and to Mr. Charles Edward Marshall, of Glen Mary, Kentucky, for permission to photograph the portrait of Colonel Thomas Marshall.

The large number of citations has made abbreviations necessary. At the end of each volume will be found a careful explanation of references, giving the full title of the work cited, together with the name of the author or editor, and a designation of the edition used.

The index has been made by Mr. David Maydole Matteson, of Cambridge, Massachusetts, and his careful work has added to whatever of value these volumes possess.
