In February, 1909, on the invitation of President Roosevelt, a North American Conservation Conference, attended by representatives of the United States, Canada, and Mexico, was held at the White House. A declaration of principles was drawn up and the suggestion made that all the nations of the world should be invited to meet in a World Conservation Conference. The President forthwith addressed to forty-five nations a letter inviting them to assemble at The Hague for such a conference; but, as he has laconically expressed it, "When I left the White House the project lapsed." CHAPTER X. BEING WISE IN TIME Perhaps the most famous of Roosevelt's epigrammatic sayings is, "Speak softly and carry a big stick." The public, with its instinctive preference for the dramatic over the significant, promptly seized upon the "big stick" half of the aphorism and ignored the other half. But a study of the various acts of Roosevelt when he was President readily shows that in his mind the "big stick" was purely subordinate. It was merely the ultima ratio, the possession of which would enable a nation to "speak softly" and walk safely along the road of peace and justice and fair play. The secret of Roosevelt's success in foreign affairs is to be found in another of his favorite sayings: "Nine-tenths of wisdom is to be wise in time." He has himself declared that his whole foreign policy "was based on the exercise of intelligent foresight and of decisive action sufficiently far in advance of any likely crisis to make it improbable that we would run into serious trouble."
