If they disobey him, he has various means of punishment at his command. He can banish them from court for a long term; he can deprive them temporarily, or for all time, of the prerogatives, the privileges, and the honors due to their rank; he can suspend their allowances from the national treasury, or from the family property, or can stop it altogether; he can take from them the control of any estates which they may have inherited, and confide the administration thereof to curators appointed for the purpose; finally, he can subject them to various forms of arrest, as he once did in the case of his brother-in-law, Prince Frederick-Leopold; while in very extreme cases he can place the offending relative under restraint in an asylum for the insane on the pretext of dementia, as has been done in the case of Princess Louise of Coburg, daughter of King Leopold of Belgium, and mother of Princess "Dolly" of Coburg, who is now the wife of Duke Ernest-Gunther of Schleswig-Holstein. "_Aux arrêts_," or confinement to one's quarters, is the most common form of punishment inflicted by Old World monarchs upon those of their kith and kin who have failed to comply with their behests, and there is scarcely a single sovereign or prince of the blood, who has not been subjected to this species of discipline at one time or another of his career. Thus the late Emperor Frederick, prior to his accession to the throne, but long after his marriage, was sentenced to several weeks' detention in his palace under strict arrest, as a punishment for a little joke which he had played during the course of a military inspection. He had been protesting for a long time against the tightness of the uniforms, and of the belts of the rank and file of the infantry, declaring that it impeded the movements and play of the muscles of the men, to such an extent as to deprive them of more than fifty per cent, of their usefulness. One day, during an inspection of the division of guards at Potsdam, while the troops happened to be standing at ease, he walked along the front rank of the first regiment, accompanied by a number of officers, with whom he had just been discussing this very question of equipment; suddenly, he stopped short in his walk, and extracting a piece of gold from his pocket, dropped it on the ground, and told the men nearest him to pick it up, adding that whoever got hold of it first, might keep it! Several of them made frantic attempts to bend down in order to get the money, but so tight were their uniforms and belts that they found it absolutely impossible to reach, the coin, which Emperor Frederick ultimately picked up himself, and handed to them. "And how do you expect to win battles with soldiers hampered to such an extent as that in their movements?" he exclaimed contemptuously to the officers around him. "What greater demonstration than this is needed to prove the justice of my argument?"
