Celery is eaten with the fingers.

Change of residence.  Women.  After a change of
       residence, the cards of the entire family
       should be sent out as soon as possible.

Chaperone.  A chaperone takes precedence of her
       charge in entering drawing or dancing rooms
       and on ceremonious occasions.  At an entertainment
       both enter together, and the chaperone
       should introduce her protege to the
       hostess and to others.  The two should remain
       together during the evening.  In a
       general way the chaperon takes under her
       charge the social welfare of her protege.

  Balls.  A mother should attend balls with her
       daughters, going and returning with them,
       and if she is not invited, it is in good taste
       for the daughters to decline the invitation. 
       A father can act as escort, if need be, instead
       of the mother.  A mother can delegate her
       powers to some one else when requested to
       act as a chaperone.

  Men calling.  A man should ask the chaperone’s
       permission to call upon her protege,
       and once it is granted no further permission
       is necessary.  The chaperone should be present
       while a debutante receives male callers
       the first year, and when the first call is made
       she should be present throughout the evening
       and should decide as to the necessity
       of her presence during subsequent visits.

  Cards.  A chaperone introducing and accompanying
       young women should leave her own
       card with that of her protege.

  Dances.  The chaperone should give her
       permission to a man who desires to dance,
       promenade, or go to supper with her charge,
       who should not converse with him at length
       save at the chaperon’s side, and the chaperon
       should accompany both to supper.  If without
       an escort, the young woman may accept
       the invitation of her last partner before
       supper is announced.

  Introductions.  A man should never be introduced
       direct by card or letter to a young
       unmarried woman.  If he desires to be
       introduced, the letter or card of introduction
       should be addressed to her chaperone or
       mother, who may then introduce him to the
       young woman if she deems it advisable.

       At an entertainment a chaperone may ask
       a young man if he wishes to be introduced
       to the one under her care.

  Letters of introduction.  A man having a
       letter of introduction to a young woman
       should present it in person to the chaperone. 
       If the latter is out when he calls, he should
       mail it to her, and she may then notify him
       when he may call, and should herself be
       present.
