The lady of the house--who should, if possible, know the name of everybody who enters the room--must stand near the door, so as to receive her guests, to each of whom she must find something to say, no matter how trifling. The host must also be near, to welcome arrivals, and the sons to introduce people. The young ladies must see that the dances are kept up, and should not dance themselves till they have found partners for all their friends. They may with perfect propriety ask any gentleman present to be introduced to a partner, and he is bound to accept the invitation; but the lady must be careful whom she asks. Many present may be entire strangers to her. Miss A. has brought her betrothed; Miss B. introduces her cousin, Captain ---, on a short leave of absence from his regiment in Texas; Miss C. presents her brother, just returned from California; Miss D. begs leave to introduce a cousin on a short visit to the city; Miss E., a belle, has informed a dozen or two of her admirers where they may bow to her on the evening of the ball. All these strangers bow to the hostess, and must be provided with partners. The "Man in the Club Window" says: "I have known a case where a distinguished-looking young man, having declined the lady's invitation to dance, but being pressed by,' I can't make up the lancers without you,' somewhat reluctantly accepted, performed his part so well that his partner was quite _eprise_ with him, and even ventured on a little flirtation. You can imagine her dismay when, a little later in the evening, she saw her charming acquaintance carrying up a pile of plates from the kitchen to the supper-room. For the first time in her life, she had danced with an occasional waiter." If a gentleman act as escort to a lady, he must call at her house, at the hour she appoints, with a carriage, and he is expected to send a bouquet in the course of the afternoon. Upon reaching the house of the hostess for the evening, he must escort his fair charge to the dressing-room, leave her at the door, make his own toilet as rapidly as possibly, and return to meet the lady at the dressing-room door again, escort her to the ball-room, and at once to the hostess. She is obliged by etiquette to dance the first dance with him; but after that, he may with propriety allow her liberty to select other partners, always watching, however, to see that she is never neglected. He must be her escort to supper, and ready at any moment to leave the ball-room to escort her home again. If a gentleman is unaccompanied by a lady, he must invite one of the ladies of the house for the first dance, and yield gracefully if she declines on the plea of want of room or partners for all her guests, consenting smilingly if she requests him to lead out the homeliest and most awkward of her wall-flowers.
