I, who take root and firmly cling. 

 Thought fixedness the only thing; 

 Why Nature made the butterflies, 

 (Those dreams of wings that float and hover 

 At noon tlie slumberous poppies over,) 

 Was something hidden from mine eyes, 



Till once, upon a rock's brown bosom, 

 Bright as a thorny cactus-blossom, 

 I saw a butterfly at rest ; 

 Then first of both I felt the beauty ; 

 The airy whim, the grim-set duty 

 Each from the other took its best.
