Nothing would afford me greater happiness than to know, as I believe will be the case, that, at some future day, the nations of the earth will agree upon some sort of congress, which shall take cognizance of international questions of difficulty, and whose decisions will be as binding as the decision of our Supreme Court is binding on us. It is a dream of mine that some such solution may be found for all questions of difficulty that may arise between nations.
