Roosevelt's official day ended at half-past nine or ten in the evening, and then, after the family had gone to bed, he sat down to read or write, and it was long after midnight, sometimes one o'clock, some times much later, before he turned in himself. He regarded the preservation of health as a duty; and well he might so regard it, because in childhood he had been a sickly boy, with apparently only a life of invalidism to look forward to. But by sheer will, and by going through physical exercises with indomitable perseverance, he had built up his body until he was strong enough to engage in all sports and in the hardships of Western life and hunting. After he became President, he allowed nothing to interfere with his physical exercise. I have spoken of his long hikes and of his vigorous games with members of the Tennis Cabinet. On many afternoons he would ride for two hours or more with Mrs. Roosevelt or some friend, and it is a sad commentary on the perpetual publicity to which the American people condemn their Presidents, that he sometimes was obliged to ride off into the country with one of his Cabinet Ministers in order to be able to discuss public matters in private with him. Roosevelt took care to provide means for exercise indoors in very stormy weather. He had a professional boxer and wrestler come to him, and when jiu-jitsu, the Japanese system of physical training, was in vogue, he learned some of its introductory mysteries from one of its foremost professors. It was in a boxing bout at the White House with his teacher that he lost the sight of an eye from a blow which injured his eyeball. But he kept this loss secret for many years. He had a wide acquaintance among professional boxers and even prize-fighters. Jeffries, who had been a blacksmith before he entered the ring, hammered a penholder out of a horseshoe and gave it to the President, a gift which Roosevelt greatly prized and showed among his trophies at Oyster Bay. John L. Sullivan, perhaps the most notorious of the champion prize-fighters of America, held Roosevelt in such great esteem that when he died his family invited the ex-President to be one of the pall-bearers. But Mr. Roosevelt was then too sick himself to be able to travel to Boston and serve. At Oyster Bay in summer, the President found plenty of exercise on the place. It contained some eighty acres, part of which was woodland, and there were always trees to be chopped. Hay-making, also, was an equally severe test of bodily strength, and to pitch hay brought every muscle into use. There, too, he had water sports, but he always preferred rowing to sailing, which was too slow and inactive an exercise for him. In old times, rowing used to be the penalty to which galley-slaves were condemned, but now it is commended by athletes as the best of all forms of exercise for developing the body and for furnishing stimulating competition.
