The intercourse of the families of officials is regulated by the rules which govern the officials themselves.
Besides the public levees of the President, the ladies of the White House hold receptions at stated periods, to which invitations are regularly issued. The President sometimes appears upon these occasions, but is under no obligation to do so.
It has long been the custom for the President to give a series of State Dinners during the session of Congress, to which the various members of that body, the higher Government officials and the Diplomatic Corps are successively invited. In order to show attention to all, and offend none, it is necessary to give quite a number of these dinners during the session.
[The proper titles to be used in addressing the President, Members of the Cabinet, Members of Congress, Judges of the Supreme Court and other Government officials, are found in the Department on “Letter-Writing.”]
