All other contributions must be sought for upon internal evidence, and such evidence can never be conclusive. No one is yet certain who wrote some of the essays of “The Federalist,” and it is impossible to point to unsigned papers in the _Evening Post_ and say, “These are Hamilton’s.” The style might be that of almost any other cultivated man of legal training; the content might be that of such other able contributors as Gouverneur Morris or Oliver Wolcott. It is possible that a long, well-written article of March 12, 1802, upon Representative Giles’s speech for the repeal of the Judiciary Act is Hamilton’s; it contains a good deal of information upon the proposals which Hamilton made for indirect taxation when he was Secretary of the Treasury. It is possible that Hamilton dictated part or all of the attack of April 19, 1803, upon the Manhattan Bank founded by De Witt Clinton’s faction, for it contains much sound disquisition upon the principles of public finance. It is quite possible that he furnished at least an outline for the article of July 9, 1803, upon neutrality, which deals in considerable part with the rôle he, Knox, and Jefferson played in the Genet affair; and that he assisted later the same month in an article upon the funding system, land tax, and national debt. But it is bootless to pile up such conjectures. The editorials upon the diplomatic aspects of the Louisiana treaty, the Chase impeachment, and the navigation of the Mississippi certainly represented Hamilton’s views.
