By the time his experiences in the West were over, Roosevelt's fight for health had achieved its purpose. Bill Sewall, the woodsman who had introduced the young Roosevelt to the life of the out-of-doors in Maine, and who afterward went out West with him to take up the cattle business, offers this testimony: "He went to Dakota a frail young man, suffering from asthma and stomach trouble. When he got back into the world again, he was as husky as almost any man I have ever seen who wasn't dependent on his arms for his livelihood. He weighed one hundred and fifty pounds, and was clear bone, muscle, and grit." This battle won by the force of sheer determination, the young Roosevelt never ceased fighting. He knew that the man who neglects exercise and training, no matter how perfect his physical trim, is certain to "go back." One day many years afterward on Twenty-third Street, on the way back from an Outlook editorial luncheon, I ran against his shoulder, as one often will with a companion on crowded city streets, and felt as if it were a massive oak tree into which I had bumped. Roosevelt the grown man of hardened physique was certainly a transformation from that "reed shaken with the wind" of his boyhood days. When Theodore Roosevelt left Harvard in 1880, he plunged promptly into a new fight--in the political arena. He had no need to earn his living; his father had left him enough money to take care of that. But he had no intention or desire to live a life of leisure. He always believed that the first duty of a man was to "pull his own weight in the boat"; and his irrepressible energy demanded an outlet in hard, constructive work. So he took to politics, and as a good Republican ("at that day" he said, "a young man of my bringing up and convictions, could only join the Republican party") he knocked at the door of the Twenty-first District Republican Association in the city of New York. His friends among the New Yorkers of cultivated taste and comfortable life disapproved of his desire to enter this new environment. They told him that politics were "low"; that the political organizations were not run by "gentlemen," and that he would find there saloonkeepers, horse-car conductors, and similar persons, whose methods he would find rough and coarse and unpleasant. Roosevelt merely replied that, if this were the case, it was those men and not his "silk-stocking" friends who constituted the governing class--and that he intended to be one of the governing class himself. If he could not hold his own with those who were really in practical politics, he supposed he would have to quit; but he did not intend to quit without making the experiment.
