Analysis of The Barn and the Down

t stood in the sunset sky
Like the straight-backed down,
Many a time - the barn
At the edge of town,

So huge and dark that it seemed
It was the hill
Till the gable's precipice proved
It impossible.

Then the great down in the west
Grew into sight,
A barn stored full to the ridge
With black of night;

And the barn fell to a barn
Or even less
Before critical eyes and its own
Late mightiness.

But far down and near barn and I
Since then have smiled,
Having seen my new cautiousness
By itself beguiled

To disdain what seemed the barn
Till a few steps changed
It past all doubt to the down;
So the barn was avenged.
