BEING out of heart with government 
I took a broken root to fling 
Where the proud, wayward squirrel went, 
Taking delight that he could spring; 
And he, with that low whinnying sound 
That is like laughter, sprang again 
And so to the other tree at a bound. 
Nor the tame will, nor timid brain, 
Nor heavy knitting of the brow 
Bred that fierce tooth and cleanly limb 
And threw him up to laugh on the bough; 
No govermnent appointed him.
William Butler Yeats
