His indefatigable activity both of mind and body formed a strong contrast to the lethargy of early years. His widely scattered empire, spreading over the Low Countries, Spain, Germany, and the New World, presented embarrassments which most princes would have found it impossible to overcome. At least they would have been compelled to govern, in a great measure, by deputy,--to transact their business by agents. But Charles chose to do everything himself,--to devise his own plans, and to execute them in person. The number of his journeys by land and by water, as noticed in his farewell address, is truly wonderful; for that was not the day of steamboats and railways. He seemed to lead the life of a courier. But it was for no trivial object that he made these expeditions. He knew where his presence was needed; and his promptness and punctuality brought him, at the right time, on the right spot. No spot in his broad empire was far removed from him. He seemed to possess the power of ubiquity. The consciousness of his own strength roused to a flame the spark of ambition which had hitherto slept in his bosom. His schemes were so vast, that it was a common opinion he aspired to universal monarchy. Like his grandfather, Ferdinand, and his own son, Philip, he threw over his schemes the cloak of religion. Or, to deal with him more fairly, religious principle probably combined with personal policy to determine his career. He seemed always ready to do battle for the Cross. He affected to identify the cause of Spain with the cause of Christendom. He marched against the Turks, and stayed the tide of Ottoman inroad in Hungary. He marched against the Protestants, and discomfited their armies in the heart of Germany. He crossed the Mediterranean, and humbled the Crescent at Algiers. He threw himself on the honor of Francis, and travelled through France to take vengeance on the rebels of Flanders. He twice entered France as an enemy, and marched up to the gates of Paris. Instead of the modest legend on his maiden shield; he now assumed the proud motto, "_Plus ultra_;" and he vindicated his right to it, by sending his fleets across the ocean, and by planting the banner of Castile on the distant shores of the Pacific. In these enterprises he was generally successful. His success led him to rely still more on himself. "Myself and the lucky moment," was his favorite saying. The "star of Austria," was still a proverb. It was not till the evening of life that he complained of the fickleness of fortune; that his star, as it descended to the horizon, was obscured by clouds and darkness. Thus Charles's nerves were kept in a state of perpetual excitement. No wonder that his health should have sunk under it; like a plant forced by extraordinary stimulants to an unnatural production at the expense of its own vitality.
