Marshall's great Constitutional opinions grew out of, or were addressed to, serious public conditions, national in extent. In these volumes the effort is made to relate the circumstances that required him to give to the country those marvelous state papers: for Marshall's opinions were nothing less than state papers and of the first rank. In order to understand the full meaning of his deliverances and to estimate the just value of his labors, it is necessary to know the historical sources of his foremost expositions of the Constitution, and the historical purposes they were intended to accomplish. Without such knowledge, Marshall's finest pronouncements become mere legal utterances, important, to be sure, but colorless and unattractive.

It is worthy of repetition, even in a preface, that the history of the times is a part of his greatest opinions; and that, in the treatment of them a rÉsumÉ of the events that produced them must be given. For example, the decision of Marbury vs. Madison, at the time and in the manner it was rendered, was compelled by the political situation then existing, unless the principle of judicial supremacy over legislation was to be abandoned. The Judiciary Debate of 1802 in Congress—one of the most brilliant as well as most important legislative engagements in parliamentary history—can no more be overlooked by the student of American Constitutional development, than the opinion of Marshall in Marbury vs. Madison can be disregarded.

Again, in Cohens vs. Virginia, the Chief Justice rises to heights of exalted—almost emotional—eloquence. Yet the case itself was hardly more than a police court controversy. If the trivial fine of itinerant peddlars of lottery tickets were alone involved, Marshall's splendid passages become unnecessary and, indeed, pompous rhetoric. But when the curtains of history are raised, we see the heroic part that Marshall played and realize the meaning of his powerful language. While Marshall's opinion in M'Culloch vs. Maryland, even taken by itself, is a major treatise on constitutional government, it becomes a fascinating chapter in an engaging story, when read in connection with an account of the situation which compelled that outgiving.

The same thing is true of his other historic utterances. Indeed, it may be said that his weightiest opinions were interlocking parts of one great drama.

Much space has been given to the conspiracy and trials of Aaron Burr. The combined story of that adventure and of those prosecutions has not hitherto been told. In the conduct of the Burr trials, Marshall appears in a more intimate and personal fashion than in any other phase of his judicial career; the entire series of events that make up that page of our history is a striking example of the manipulation of public opinion by astute politicians, and is, therefore, useful for the self-guidance of American democracy. Most important of all, the culminating result of this dramatic episode was the definitive establishment of the American law of treason.

In narrating the work of a jurist, the temptation is very strong to engage in legal discussion, and to cite and comment upon the decisions of other courts and the opinions of other judges. This, however, would be the very negation of biography; nor would it add anything of interest or enlightenment to the reader. Such information and analysis are given fully in the various books on Constitutional law and history, in the annotated reports, and in the encyclopÆdias of law upon the shelves of every lawyer. Care, therefore, has been taken to avoid making any part of the Life of John Marshall a legal treatise.

The manuscript of these volumes has been read by Professor Edward Channing of Harvard; Professor Max Farrand of Yale; Professor Edward S. Corwin of Princeton; Professor William E. Dodd of Chicago University; Professor Clarence W. Alvord of the University of Illinois; Professor James A. Woodburn of Indiana University; Professor Charles H. Ambler of the University of West Virginia; Professor Archibald Henderson of the University of North Carolina; Professor D. R. Anderson of Richmond (Va.) College; and Dr. H. J. Eckenrode of Richmond, Virginia.

The manuscript of the third volume has been read by Professor Charles A. Beard of New York; Dr. Samuel Eliot Morison of Harvard; and Mr. Harold J. Laski of Harvard. The manuscript of both the third and fourth volumes has been read, from the lawyer's point of view, by Mr. Arthur Lord of Boston, President of the Massachusetts Bar Association, and by Mr. Charles Martindale of Indianapolis.

The chapters on the Burr conspiracy and trials have been read by Professor Walter Flavius McCaleb of New York; Professor Isaac Joslin Cox of the University of Cincinnati; and Mr. Samuel H. Wandell of New York. Chapter Three of Volume Three (Marbury vs. Madison) has been read by the Honorable Oliver Wendell Holmes, Associate Justice of the Supreme Court of the United States; by the Honorable Philander Chase Knox, United States Senator; and by Mr. James M. Beck of New York. Other special chapters have been read by the Honorable Henry Cabot Lodge, United States Senator; by Professor J. Franklin Jameson of the Department of Historical Research of the Carnegie Institution of Washington; by Professor Charles H. Haskins of Harvard; by Dr. William Draper Lewis of Philadelphia, former Dean of the Law School of the University of Pennsylvania; and by Mr. W. B. Bryan of Washington.

All of these gentlemen have made valuable suggestions of which I have availed myself, and I gratefully acknowledge my indebtedness to them. The responsibility for everything in these volumes, however, is, of course, exclusively mine; and, in stating my appreciation of the comment and criticism with which I have been favored, I do not wish to be relieved of my burden by allowing the inference that any part of it should be assigned to others.

I also owe it to myself again to express my heavy obligation to Mr. Worthington Chauncey Ford, Editor of the Massachusetts Historical Society. As was the case in the preparation of the first two volumes of this work, Mr. Ford has extended to me the resources of his ripe scholarship; while his wise counsel, steady encouragement, and unselfish assistance, have been invaluable in the prosecution of a long and exacting task.

I also again acknowledge my indebtedness to Mr. Lindsay Swift, Editor of the Boston Public Library, who has read with critical care not only the many drafts of the manuscript, but also the proofs of the entire work. Mr. Swift has given, unstintedly, his rare literary taste and critical accomplishment to the examination of these pages.

I also tender my hearty thanks to Dr. Gardner Weld Allen of Boston, who has generously directed the preparation of the bibliography and personally revised it.

Mr. David Maydole Matteson of Cambridge, Massachusetts, has made the index of these volumes as he made that of the first two volumes, and has combined both indexes into one. In rendering this service, Mr. Matteson has also searched for points where text and notes could be made more accurate; and I wish to express my appreciation of his kindness.

My thanks are also owing to the staff of The Riverside Press, and particularly to Mr. Lanius D. Evans, to whose keen interest and watchful care in the production of this work I am indebted for much of whatever exactitude it may possess.

The manuscript sources have been acknowledged, in all instances, in the footnotes where references to them have been made, except in the case of the letters of Marshall to his relatives, for which I again thank those descendants and connections of the Chief Justice named in the preface to Volumes One and Two. The Hopkinson manuscripts are in the possession of Mr. Edward Hopkinson of Philadelphia, to whom I am indebted for the privilege of inspecting this valuable source and for furnishing me with copies of important letters.

In preparing these volumes, Mr. A. P. C. Griffin, Assistant Librarian, and Mr. John Clement Fitzpatrick, of the Manuscript Division of the Library of Congress, have been even more obliging, if possible, than they were in the preparation of the first part of this work. The officers and their assistants of the Boston Public Library, the Boston AthenÆum, the Massachusetts State Library, the Massachusetts Historical Society, the Pennsylvania Historical Society, the Virginia State Library, the Indiana State Library, and the Indianapolis City Library, have assisted whole-heartedly in the performance of my labors; and I am glad of the opportunity to thank all of them for their interest and help.
