The first bell is silver, 
And breathing darkness I think only of the long scythe of time. 
The second bell is crimson, 
And I think of a holiday night, with rockets 
Furrowing the sky with red, and a soft shatter of stars. 
The third bell is saffron and slow, 
And I behold a long sunset over the sea 
With wall on wall of castled cloud and glittering balustrades. 
The fourth bell is color of bronze, 
I walk by a frozen lake in the dun light of dusk: 
Muffled crackings run in the ice, 
Trees creak, birds fly. 
The fifth bell is cold clear azure, 
Delicately tinged with green: 
One golden star hangs melting in it, 
And towards this, sleepily, I go. 
The sixth bell is as if a pebble 
Had been dropped into a deep sea far above me . . . 
Rings of sound ebb slowly into the silence.
