The sky is dark and the hills are white 
As the storm-king speeds from the north to-night, 
And this is the song the storm-king sings, 
As over the world his cloak he flings: 
 "Sleep, sleep, little one, sleep;" 
He rustles his wings and gruffly sings: 
 "Sleep, little one, sleep." 
 
On yonder mountain-side a vine 
Clings at the foot of a mother pine; 
The tree bends over the trembling thing, 
And only the vine can hear her sing: 
 "Sleep, sleep, little one, sleep; 
What shall you fear when I am here? 
 Sleep, little one, sleep." 
 
The king may sing in his bitter flight, 
The tree may croon to the vine to-night, 
But the little snowflake at my breast 
Liketh the song I sing the best,-- 
 Sleep, sleep, little one, sleep; 
Weary thou art, anext my heart 
 Sleep, little one, sleep.
Eugene Field
