A ball is the only social function in America to which such qualifying words as splendor and magnificence can with proper modesty of expression be applied. Even the most elaborate wedding is not quite "a scene of splendor and magnificence" no matter how luxurious the decorations or how costly the dress of the bride and bridesmaids, because the majority of the wedding guests do not complete the picture. A dinner may be lavish, a dance may be beautiful, but a ball alone is prodigal, meaning, of course, a private ball of greatest importance. On rare occasions, a great ball is given in a private house, but since few houses are big enough to provide dancing space for several hundred and sit-down supper space for a greater number still, besides smoking-room, dressing-room and sitting-about space, it would seem logical to describe a typical ball as taking place in the ballroom suite built for the purpose in nearly all hotels. =A HOSTESS PREPARES TO GIVE A BALL= The hostess who is not giving the ball in her own house goes first of all to see the manager of the hotel (or of whatever suitable assembly rooms there may be) and finds out which evenings are available. She then telephones--probably from the manager's office--and engages the two best orchestras for whichever evening both the orchestras and the ballroom are at her disposal. Of the two, music is of more importance than rooms. With perfect music the success of a ball is more than three-quarters assured; without it, the most beautiful decorations and most delicious supper are as flat as a fallen soufflé. You cannot give a ball or a dance that is anything but a dull promenade if you have dull music. To illustrate the importance that prominent hostesses attach to music: a certain orchestra in New York to-day is forced to dash almost daily, not alone from party to party, but from city to city. Time and again its leader has conducted the music at a noon wedding in Philadelphia, and a ball in Boston; or a dancing tea in Providence and a ball that evening in New York; because Boston, Providence, New York and Philadelphia hostesses all at the present moment clamor for this one especial orchestra. The men have a little more respite than the leader since it is his "leading" that every one insists upon. Tomorrow another orchestra will probably make the daily tour of various cities' ballrooms. At all balls, there must be two orchestras, so that each time one finishes playing the other begins. At very dignified private balls, dancers should not stand in the middle of the floor and clap as they do in a dance hall or cabaret if the music ends. On the other hand, the music should not end. Having secured the music and engaged the ballroom, reception rooms, dressing-rooms and smoking-room, as well as the main restaurant (after it is closed to the public), the hostess next makes out her list and orders and sends out her invitations. =INVITATIONS=
