A social letter begins:  My dear Senator
       Wilson, and ends:  Believe me, most sincerely
       yours.

       The address on the envelope is:  Senator
       John J. Wilson, or, To the Hon. John J.
       Wilson.

Servants-Tipping.  It is customary for guests leaving
       a house after a visit to tip the servants,
       unless positively requested by the hostess not
       to do so.  The average tip would be one
       dollar, with more for extra attention.

SHAKING HANDS.

  Dances.  It is not customary to shake hands at
       formal dances.

  Host and hostess.  The host and the hostess
       should shake hands with each guest as they
       arrive.

If guest takes leave of host and hostess, they should shake hands.  If they are surrounded by guests, a pleasant nod of farewell is admissible.

  Men.  At a wedding, the opera, or a dance, and
       all very formal occasions, gloves should not
       be removed when shaking hands.

If the hostess wears gloves at any formal affair, a man wears his when he shakes hands with her.  He should give a slight pressure only.

A man with hands gloved should never shake hands with a woman without an apology for so doing, unless she likewise wears gloves.  A sudden meeting, etc., may make a handshaking in gloves unavoidable.  Unless the other party is gloved, a man should apologize.

       When men are introduced to men, they
       always shake hands.  It is bad form to crush
       the hand when shaking it.

       When introduced to a woman, men should
       bow, but not offer to shake hands.

  Calls.  If the woman is seated when a man enters
       the room, she rises to greet him, and, if
       she wishes, shakes hands.  She has the
       option to shake hands or not, and should
       make the first advances.  It is bad form for
       him to do so.

  Women.  Upon introduction, a woman may
       shake hands with either men or women, but
       a slight inclination of the body, a pleasant
       smile, and an appropriate remark are more
       correct.

       A young girl, upon being introduced to an
       older woman, should await the action of the
       elder, who will shake hands if kindly disposed.

       If one person extends the hand, it should
       be accepted without the slightest hesitation,
       to avoid embarrassment.
