Sonnet. "If in thy heart the spring of joy remains"

If in thy heart the spring of joy remains,
  All beauteous things, being reflected there,
  Most beautiful and joyful do appear;
  But if that treasure hath been from thee ta'en,
  If emptiness, and darkness, in thy heart
  Sit silent—from all nature doth depart
  Its joy and glory, and all beauty seems
  Hollow and strange.—The poet's noble dreams,
  The voice of music and of song, the sight
  Of evening shadows, and of morning light,
  Flowers, and bright faces—youth, and hope, and love,
  Who hand in hand over life's threshold move
  Like conquerors to a triumph—all things fair,
  Shining upon thee darken thy despair.
