An invitation to a ball should be sent out from two to three weeks before the evening, and should be answered within a day or two of being received. As to the number of guests to be invited, no precise rules can be laid down. The size of your room does not seem to be any guide. The custom is to ask rather more than twice as many as your rooms will hold; but one-third more will be enough, as it will allow of disappointments at the last moment, even if all have accepted the invitations. Besides, during the gayest of the season, the fashion of going to several balls in one night necessitates ensuring the presence of a sufficiently large number of guests all through the evening. If you really wish for dancing, do not exceed the last limits. If, however, your aim is to have the largest ball of the season, a crush and crowd, to make a sensation, then invite your entire visiting list, and endure the consequences. A hundred guests constitute a "ball;" over that, a "large ball;" under that, merely a "dance."
