The supper-room at a ball is thrown open generally at twelve o'clock. The table is made as elegant as beautiful china, cut-glass and an abundance of flowers can make it. The hot dishes are oysters, stewed, fried, broiled and scalloped, chicken, game, etc., and the cold dishes are such as boned turkey, _boeuf a la mode_, chicken salad, lobster salad and raw oysters. When supper is announced, the host leads the way with the lady to whom he wishes to show especial attention, who may be an elderly lady, or a stranger or a bride. The hostess remains until the last, with the gentleman who takes her to supper, unless some distinguished guest is present, with whom she leads the way. No gentleman should ever go into the supper-room alone, unless he has seen every lady enter before him. When ladies are left unattended, gentlemen, although strangers, are at liberty to offer their services in waiting upon them, for the host and hostess are sufficient guarantees for the respectability of their guests. THE NUMBER TO INVITE. Persons giving balls or dancing parties should be careful not to invite more than their rooms will accommodate, so as to avoid a crush. Invitations to crowded balls are not hospitalities, but inflictions. A hostess is usually safe, however, in inviting one-fourth more than her rooms will hold, as that proportion of regrets are apt to be received. People who do not dance will not, as a rule, expect to be invited to a ball or dancing party. DUTIES OF GUESTS. Some persons may be astonished to learn that any duties devolve upon the guests. In fact there are circles where all such duties are ignored. It is the duty of every person who has at first accepted the invitation, and subsequently finds that it will be impossible to attend, to send a regret, even at the last moment, and as it is rude to send an acceptance with no intention of going, those who so accept will do well to remember this duty. It is the duty of every lady who attends a ball, to make her toilet as fresh as possible. It need not be expensive, but it should at least be clean; it may be simple, but it should be neither soiled nor tumbled. The gentlemen should wear evening dress. It is the duty of every person to arrive as early as possible after the hour named, when it is mentioned in the invitation.
