Last June trouble which had existed for some time between the Republics of Salvador, Guatemala, and Honduras culminated in war--a war which threatened to be ruinous to the countries involved and very destructive to the commercial interests of Americans, Mexicans, and other foreigners who are taking an important part in the development of these countries. The thoroughly good understanding which exists between the United States and Mexico enabled this Government and that of Mexico to unite in effective mediation between the warring Republics; which mediation resulted, not without long-continued and patient effort, in bringing about a meeting of the representatives of the hostile powers on board a United States warship as neutral territory, and peace was there concluded; a peace which resulted in the saving of thousands of lives and in the prevention of an incalculable amount of misery and the destruction of property and of the means of livelihood. The Rio Conference past the following resolution in reference to this action: "That the Third International American Conference shall address to the Presidents of the United States of America and of the United States of Mexico a note in which the conference which is being held at Rio expresses its satisfaction at the happy results of their mediation for the celebration of peace between the Republics of Guatemala, Honduras, and Salvador." This affords an excellent example of one way in which the influence of the United States can properly be exercised for the benefit of the peoples of the Western Hemisphere; that is, by action taken in concert with other American republics and therefore free from those suspicions and prejudices which might attach if the action were taken by one alone. In this way it is possible to exercise a powerful influence toward the substitution of considerate action in the spirit of justice for the insurrectionary or international violence which has hitherto been so great a hindrance to the development of many of our neighbors. Repeated examples of united action by several or many American republics in favor of peace, by urging cool and reasonable, instead of excited and belligerent, treatment of international controversies, can not fail to promote the growth of a general public opinion among the American nations which will elevate the standards of international action, strengthen the sense of international duty among governments, and tell in favor of the peace of mankind. I have just returned from a trip to Panama and shall report to you at length later on the whole subject of the Panama Canal.
