The following extracts from a letter of the late Mr. Justice Story, of the Supreme Court of the United States, dated January 14th, 1837--and from one from Mr. Justice McLean, still of that high court, dated 24th of February, 1843--sufficiently attest the value of the Compilation, and the excellence of its execution. Mr. Justice Story says: "I have examined these volumes with great attention, and I am entirely satisfied with the plan and execution of them. I have, for many years, deemed the publication of the Debates in Congress, interwoven as they should be, and as they are in your plan, with the proceedings explanatory of them, one of the most important and valuable enterprises for public patronage. In an historical view, it will reflect the strongest and best lights upon the nature and operations of the Government itself, its powers, its duties, and its policy. As a means of expounding and interpreting the Constitution itself, it can scarcely be over-estimated. When I was employed in the task of preparing my Commentaries on the Constitution I constantly had recourse to this source of information in all cases within my reach. I had occasion then deeply to regret, however, that many of my researches terminated in disappointment from there not being any complete collection of the debates in print, or at least none in any one repository, or without large chasms, which it was difficult if not impossible to supply. If any such collection had existed, I am satisfied that it would have enabled me to make my own work far more accurate, full, and satisfactory than it now is. The Parliamentary Debates of England have been long since published, and constitute, in a political and historical view, some of the most authentic and useful documents for statesmen and jurists which have ever issued from the press. They are an indispensable part of the library of every real British statesman. A similar publication of all the Debates in Congress would be, if possible, of more permanent and extensive value to us, since questions of constitutional law and general public policy are more frequent topics of public debate here than in England. Indeed, I do not well see how American statesmen, seeking a profound knowledge of the nature and operations of our Government, can well do without them. At all events, if published, they would and ought to be found in the library of every American statesman, lawyer, and judge, who should aspire to an exact or thorough knowledge of our Constitution, laws, or national policy." Mr. Justice McLean says:
