As the President of the United States holds the highest official rank in political life, so is he also by virtue of that office, awarded precedence in social life. There is no necessity of special formalities to form his acquaintance, and he receives calls without being under any obligation to return them. He may be addressed either as "Mr. President," or "Your Excellency." Sometimes he gives up the morning hours to receiving calls, and at such times precedence is given to such people as have business with him, over parties who go to make a formal call. In either case, the caller is shown to the room occupied by the President's secretaries, presents his card and waits his turn to be admitted. If the caller has no business, but goes out of curiosity, he pays his respects and withdraws to make room for others. It is better in making a private call, to secure the company of some official or some friend of the President to introduce you. RECEPTIONS AT THE WHITE HOUSE. Stated receptions are given at the White House by the President during sessions of congress, and all are at liberty to attend them. Sometimes these are morning, and sometimes evening, receptions. Upon entering the reception room, the caller gives his name to the usher, who announces it, and upon approaching the President is introduced, by some official to whom the duty is assigned, both to the President and to the members of his family who receive with him. The callers pass on, after being introduced, mingle in social intercourse and view the various rooms until ready to depart. If a caller wishes he may leave his card. The same rules of etiquette prevail at state dinners given by the President as at any formal dinner, precedence being given to guests according to official rank and dignity. An invitation by the President must be accepted, and it is admissible to break any other engagement already made; however, it is necessary to explain the cause, in order to avoid giving offense. It is not regarded as discourteous to break an engagement for this reason. The wife of the President is not under obligation to return calls, though she may visit those whom she wishes to favor with such attentions. Other members of the President's family may receive and return calls. NEW-YEAR'S RECEPTIONS AT THE WHITE HOUSE. As the New-Year's receptions at the White House are the most ceremonious occasions of the executive mansion, it is the custom of the ladies who attend them to appear in the most elegant toilets suited to a morning reception. Members of foreign legations appear in the court dresses of their respective countries on this occasion, in paying their respects to the President of the United States. ORDER OF OFFICIAL RANK.
