Invocation To Youth

COME then, as ever, like the wind at morning!
  Joyous, O Youth, in the aged world renew
Freshness to feel the eternities around it,
  Rain, stars and clouds, light and the sacred dew.
  The strong sun shines above thee:
  That strength, that radiance bring!
  If Winter come to Winter,
  When shall men hope for Spring?
