That was the chirp of Ariel 
You heard, as overhead it flew, 
The farther going more to dwell, 
And wing our green to wed our blue; 
But whether note of joy or knell, 
Not his own Father-singer knew; 
Nor yet can any mortal tell, 
Save only how it shivers through; 
The breast of us a sounded shell, 
The blood of us a lighted dew.
George Meredith
