• Look, the world's comforter, with weary gait,
    His day's hot task hath ended in the west:
    The owl, night's herald, shrieks-'tis very late;
    The sheep are gone to fold, birds to their nest;
    And coal-black clouds, that shadow heaven's light,
    Do summon us to part, and bid good night.
