The Letters of Theodore Roosevelt constitute a major contribution to the field of American history and literature. At the same time, they present an autobiography of matchless candor and vitality. They are at once a mine of information for the historian, a case study in astute and vigorous political leadership, and a delight to the general reader. All the letters needed to reveal Roosevelt's thought and action in his public and private life are included, with appropriate editorial comment; and each is printed in its entirety. In the letters of 1905-1909, Roosevelt's "big stick" carries increasing weight at home and abroad. These are the years of the fleet's cruise around the world, of trust-busting and railroad regulation and currency control, and the building of the Panama Canal. They include the Panic of 1907, "Nature Faking," conservation, the choice of a successor, and the bitter conflict between President and Congress in the closing days of the administration.
