MALCOLM
  1    Cousins, I hope the days are near at hand
  2    That chambers will be safe.

       MENTEITH
                                                We doubt it nothing.

       SIWARD
  3    What wood is this before us?

       MENTEITH
                                                 The wood of Birnam.

       MALCOLM
  4    Let every soldier hew him down a bough
  5    And bear't before him: thereby shall we shadow
  6    The numbers of our host and make discovery
  7    Err in report of us.

       Soldiers
                                        It shall be done.

       SIWARD
  8    We learn no other but the confident tyrant
  9    Keeps still in Dunsinane, and will endure
 10    Our setting down before't.

       MALCOLM
                                             'Tis his main hope;
 11    For where there is advantage to be given,
 12    Both more and less have given him the revolt,
 13    And none serve with him but constrained things
 14    Whose hearts are absent too.

       MACDUFF
                                                 Let our just censures
 15    Attend the true event, and put we on
 16    Industrious soldiership.

       SIWARD
                                            The time approaches
 17    That will with due decision make us know
 18    What we shall say we have and what we owe.
 19    Thoughts speculative their unsure hopes relate,
 20    But certain issue strokes must arbitrate,
 21    Towards which advance the war.

          Exeunt marching.
