Christina Rossetti
Who has seen the wind?

Who has seen the wind?
  Neither I nor you:
But when the leaves hang trembling
  The wind is passing through.

Who has seen the wind?
  Neither you nor I:
But when the trees bow down their heads,
  The wind is passing by.

excerpt from A Windy Day
by James Whitcomb Riley

The dawn was a dawn of splendor,
And the blue of the morning skies
Was as placid and deep and tender
As the blue of a baby's eyes;
The sunshine flooded the mountain,
And flashed over land and sea
Like the spray of a glittering fountain.-
But the wind-the wind-Ah me!
