But when the summer day was past,
He looked to heaven and smiled at last,
Self-answered so--
"Because, O cloud,
Pressing with thy crumpled shroud
Heavily on mountain top,--
Hills that almost seem to drop
          with a misty death
To the valleys underneath,--
Valleys sighing with the torrent,--
Waters streaked with branches horrent,--
Branchless trees that shake your head
Wildly o'er your blossoms spread
Where the common flowers are found,--
Flowers with foreheads to the ground,--
Ground that shriekest while the sea
With his iron smiteth thee--
I am, besides, the only one
Who can be bright _without_ the sun.
