DUTIES OF AN ESCORT. A lady's escort should call for her and accompany her to the place of entertainment; go with her as far as the dressing-room, return to meet her there when she is prepared to go to the ball-room; enter the latter room with her and lead her to the hostess; dance the first dance with her; conduct her to the supper-room, and be ready to accompany her home whenever she wishes to go. He should watch during the evening to see that she is supplied with dancing partners. When he escorts her home she should not invite him to enter the house, and even if she does so, he should by all means decline the invitation. He should call upon her within the next two days. GENERAL RULES FOR BALLS. A young man who can dance, and will not dance, should stay away from a ball. The lady with whom a gentleman dances last is the one he takes to supper. Therefore he can make no engagement to take out any other, unless his partner is already engaged. Public balls are most enjoyable when you have your own party. The great charm of a ball is its perfect accord and harmony. All altercations, loud talking and noisy laughter are doubly ill-mannered in a ball-room. Very little suffices to disturb the whole party. In leaving a ball, it is not deemed necessary to wish the lady of the house a good night. In leaving a small dance or party, it is civil to do so. The difference between a ball and an evening party is, that at a ball there must be dancing, and at an evening party there may or may not be. A London authority defines a ball to be "an assemblage for dancing, of not less than seventy-five persons." Common civility requires that those who have not been present, but who were among the guests invited, should, when meeting the hostess the first time after an entertainment, make it a point to express some acknowledgment of their appreciation of the invitation, by regretting their inability to be present. When dancing a round dance, a gentleman should never hold a lady's hand behind him, or on his hip, or high in the air, moving her arm as though it were a pump handle, as seen in some of our western cities, but should hold it gracefully by his side. Never forget ball-room engagements, nor confuse them, nor promise two dances to one person. If a lady has forgotten an engagement, the gentleman she has thus slighted must pleasantly accept her apology. Good-breeding and the appearance of good temper are inseparable. It is not necessary for a gentleman to bow to his partner after a quadrille; it is enough that he offers his arm and walks at least half way round the room with her. He is not obliged to remain beside her unless he wishes to do so, but may leave her with any lady whom she knows. Never be seen without gloves in a ball-room, or with those of any other color than white, unless they are of the most delicate hue.
