Third—Conferences should be held from time to time to agree upon principles of international law, not already established, as their necessity shall suggest themselves. When the conclusions of the Commission shall have been submitted to the various parties to the League for a reasonable time, say a year, without calling forth objection, it shall be deemed that they acquiesce in the principles thus declared. Fourth—The members of the League shall agree that if any member of the League shall begin war against any other member of the League, without first having submitted the question, if found justiciable, to the Arbitral Court provided in the fundamental compact, or without having submitted the question, if found non-justiciable, to the Commission of Conciliation for its examination, consideration, and recommendation, then the remaining members of the League agree to join in the forcible defense of the member thus prematurely attacked. First—The first feature involves the principle of the general arbitration treaties with England and France, to which England and France agreed, and which I submitted to the Senate, and which the Senate rejected or so mutilated as to destroy their vital principle. I think it is of the utmost importance that it should be embraced in any effective League of Peace. The successful operation of the Supreme Court as a tribunal between independent States in deciding justiciable questions not in the control of Congress nor under the legislative regulation of either State furnishes a precedent and justification for this that, I hope, I have made clear. Moreover, the inveterate practice of arbitration, which has now grown to be an established custom for the disposition of controversial questions between Canada and the United States, is another confirmation of the practical character of such a court.
