Abundance of light and free ventilation are indispensable to the spirits and comfort of the dancers.

Good music is as necessary to the prosperity of a ball as good wine to the excellence of a dinner. No hostess should tax her friends for this part of the entertainment. It is the most injudicious economy imaginable. Ladies who would prefer to dance are tied to the pianoforte; and as few amateurs have been trained in the art of playing dance music with that strict attention to time and accent which is absolutely necessary to the comfort of the dancers, a total and general discontent is sure to be the result. To play dance music thoroughly well is a branch of the art which requires considerable practice. It is as different from every other kind of playing as whale fishing is from fly fishing. Those who give private balls will do well ever to bear this in mind, and to provide skilled musicians for the evening. For a small party, a piano and cornopean make a very pleasant combination. Unless where several instruments are engaged we do not recommend the introduction of the violin: although in some respects the finest of all solo instruments, it is apt to sound thin and shrill when employed on mere inexpressive dance tunes, and played by a mere dance player.

Invitations to a ball should be issued in the name of the lady of the house, and written on small note paper of the best quality. Elegant printed forms, some of them printed in gold or silver, are to be had at every stationer's by those who prefer them. The paper may be gilt-edged, but not coloured. The sealing-wax used should be of some delicate hue.

An invitation to a ball should be sent out at least ten days before the evening appointed. A fortnight, three weeks, and even a month may be allowed in the way of notice.

Not more than two or three days should be permitted to elapse before you reply to an invitation of this kind. The reply should always be addressed to the lady of the house, and should be couched in the same person as the invitation. The following are the forms generally in use:—
