There's a cry from out the loneliness -- oh, listen, Honey, listen! 
    Do you hear it, do you fear it, you're a-holding of me so? 
You're a-sobbing in your sleep, dear, and your lashes, how they glisten -- 
    Do you hear the Little Voices all a-begging me to go? 
 
All a-begging me to leave you. Day and night they're pleading, praying, 
    On the North-wind, on the West-wind, from the peak and from the plain; 
Night and day they never leave me -- do you know what they are saying? 
    "He was ours before you got him, and we want him once again." 
 
Yes, they're wanting me, they're haunting me, the awful lonely places; 
    They're whining and they're whimpering as if each had a soul; 
They're calling from the wilderness, the vast and God-like spaces, 
    The stark and sullen solitudes that sentinel the Pole. 
 
They miss my little camp-fires, ever brightly, bravely gleaming 
    In the womb of desolation, where was never man before; 
As comradeless I sought them, lion-hearted, loving, dreaming, 
    And they hailed me as a comrade, and they loved me evermore. 
 
And now they're all a-crying, and it's no use me denying; 
    The spell of them is on me and I'm helpless as a child; 
My heart is aching, aching, but I hear them, sleeping, waking; 
    It's the Lure of Little Voices, it's the mandate of the Wild. 
 
I'm afraid to tell you, Honey, I can take no bitter leaving; 
    But softly in the sleep-time from your love I'll steal away. 
Oh, it's cruel, dearie, cruel, and it's God knows how I'm grieving; 
    But His loneliness is calling, and He knows I must obey.
