Henry Wadsworth Longfellow

Behold! a giant am I!
  Aloft here in my tower,
  With my granite jaws I devour
The maize, and the wheat, and the rye,
  And grind them into flour.

I look down over the farms;
  In the fields of grain I see
  The harvest that is to be,
And I fling to the air my arms,
  For I know it is all for me.

I hear the sound of flails
  Far off, from the threshing-floors
  In barns, with their open doors,
And the wind, the wind in my sails,
  Louder and louder roars.

I stand here in my place,
  With my foot on the rock below,
  And whichever way it may blow
I meet it face to face,
  As a brave man meets his foe.

And while we wrestle and strive
  My master, the miller, stands
  And feeds me with his hands;
For he knows who makes him thrive,
  Who makes him lord of lands.

On Sundays I take my rest;
  Church-going bells begin
  Their low, melodious din;
I cross my arms on my breast,
  And all is peace within.
