When his confinement terminated he was a man. He had nearly completed his twenty-first year, and could scarcely be kept much longer under the restraints which had made his boyhood miserable. Suffering had matured his understanding, while it had hardened his heart and soured his temper. He had learnt self-command and dissimulation: he affected to conform to some of his father's views, and submissively accepted a wife, who was a wife only in name, from his father's hand. He also served with credit, though without any opportunity of acquiring brilliant distinction, under the command of Prince Eugene, during a campaign marked by no extraordinary events. He was now permitted to keep a separate establishment, and was therefore able to indulge with caution his own tastes. Partly in order to conciliate the king, and partly, no doubt, from inclination, he gave up a portion of his time to military and political business, and thus gradually acquired such an aptitude for affairs as his most intimate associates were not aware that he possessed. His favorite abode was at Rheinsberg, near the frontier which separates the Prussian dominions from the Duchy of Mecklenburg. Rheinsberg is a fertile and smiling spot, in the midst of the sandy waste of the Marquisate. The mansion, surrounded by woods of oak and beech, looks out upon a spacious lake. There Frederic amused himself by laying out gardens in regular alleys and intricate mazes, by building obelisks, temples, and conservatories, and by collecting rare fruits and flowers. His retirement was enlivened by a few companions, among whom he seems to have preferred those who, by birth or extraction, were French. With these inmates he dined and supped well, drank freely, and amused himself sometimes with concerts, and sometimes with holding chapters of a fraternity which he called the Order of Bayard; but literature was his chief resource.
