When walking with a woman, a man should walk near the curb, unless passing an obstruction-as, a building in course of construction-when she should have the outer side to protect her from harm, or from coming in contact with disagreeable things.

A man should offer his right arm to a woman, but this is rarely necessary in the daytime.  It is essential, however, and proper for him to do so after dark.

  Women.  Conduct on the street should always
       be reserved.  It is bad form to loudly laugh
       or to boldly glance at the passers-by, especially
       men.

       Women should never walk three or four
       abreast.

       Women may salute each other with a bow
       and a handshake, but a kiss in public is no
       longer in good form.

       During a promenade, where friends pass
       and repass, it is not necessary to exchange
       greetings to each other.

       A polite “Thank you,” with a bow and a
       smile, should be the reward of any man extending
       a courtesy to a woman.

  Bowing.  It is the woman’s privilege to determine
       whom she will publicly recognize, and
       therefore she should bow first to all men
       whom she desires to favor.  This formality
       is, however, unnecessary with intimate
       friends.

  Umbrellas.  These should be carried vertically,
       and never horizontally under the arm.

  Walking.  If a woman is walking with a man,
       and another man stops to speak, it would be
       in exceeding bad taste to ask him to join her.

       A woman should take a man’s right arm,
       but only after dark, unless for some special
       reason-as, weakness, etc.-it is necessary.

If a woman is walking alone, and a man of her acquaintance stops and speaks, he may ask permission to accompany her farther, which, if agreeable, should be granted.  She may stop for a few moments’ chat, and shake hands if she wishes.  If he stands before her with uncovered head, she should promptly ask him to replace his hat.  She should not block the thoroughfare, and should take the initiative if he does not step to one side.  If agreeable, an invitation may be extended to him to walk a short distance.

Subscription balls. 
  Men.  Shortly after receiving an invitation to a
       subscription ball, a man should leave a card
       for the patroness inviting him.

  Invitations.  In addition to the regular invitations,
       it is customary to guard against the
       admission of persons not really invited by
       the use of vouchers to be shown at the
       hall door, or some similar precaution is
       taken.

       When a subscriber sends an invitation and
       a voucher, he should send in the same
       envelope one of his calling cards.
