I

Wave and wind and willow-tree
Speak a speech that no man knoweth;
Tree that sigheth, wind that bloweth,
Wave that floweth to the sea:
Wave and wind and willow-tree.

Peerless perfect poets ye,
Singing songs all songs excelling,
Fine as crystal music dwelling
In a welling fountain free:
Peerless perfect poets three!

II

Wave and wind and willow-tree
Know not aught of poets' rhyming,
Yet they make a silver-chiming
Sunward-climbing minstrelsy,
Soother than all songs that be.

Blows the wind it knows not why,
Flows the wave it knows not whither,
And the willow swayeth hither
Swayeth thither witlessly,
Nothing knowing save to sigh.

William Watson
