Balls should begin at about nine o'clock in the evening, and terminate at two or three in the morning. A private ball may be a very elaborate affair, from fifty to seventy-five guests being necessary to make the occasion enjoyable. Where the size of the ball-room will permit, many more are frequently bidden. Over-crowding should be guarded against, as ruinous to the toilets of the ladies, and the pleasure of all concerned. The invitations to very elaborate affairs are sometimes sent out from three weeks to one month in advance.

It is always proper for an invited guest to solicit an invitation for a young lady visitor, or some stranger of distinction, or for a young gentleman known to be a dancing man, and it is always permissible for the hostess, if she wish, to refuse such solicitations on the ground that her list is full, and no one should feel offended at such refusal. Should the request, however, be for the admission of an eligible, dancing man, it is rarely refused.

Never more than three from one family (the mother or chaperon excepted) should accept an invitation to a ball, or party, unless in the case of a ball, where two brothers, if they dance, may be accompanied by two sisters from the same family. Those who do not dance should refuse invitations to balls (chaperons excepted). The most brilliant man who does not dance is usually out of place in an entertainment given for that sole purpose.

The ball-room should be large; the floor well waxed, or covered with drugget, and an abundance of palms and potted plants set about to make cosy nooks just lighted by a shaded lamp. Cut flowers may be massed upon the mantels with gorgeous effect. If the stairway be of sufficient breadth, it should be bravely furnished forth with plants in bloom. If it should be a first-floor room and open into the cool dusk of a faintly lighted conservatory, then it is everything to be desired for the occasion. Good ventilation is an absolute necessity.

Invite at least one quarter more guests than can be comfortably accommodated, since about that number will fail, from different causes, to accept. If it is impossible to entertain with comfort all those to whom one is socially indebted, then it is better to divide the entertainment into two or three smaller gatherings, always leaving space for as many mothers of daughters, or other appointed chaperons, as may choose to attend and who should always be included in the invitations.

Sitting accommodations should be furnished for them, as well as for those who may not be dancing. All other furniture should be removed from the rooms.

Full-dress toilets are demanded for the occasion; flowers, jewels,

"The gloss of satin and the glimmer of pearls,"

should mingle in this festivity, the gayest of our social gatherings.

The ball-room should be brilliantly, and at the same time, softly illuminated, the lights coming chiefly from the sides.
