The Alchemist in the City by Gerard Manley Hopkins

Poem was written in 1865, but not published during the author's lifetime.  His collected works were posthumously published in 1918.

My window shews the travelling clouds,
Leaves spent, new seasons, alter'd sky,
The making and the melting crowds:
The whole world passes; I stand by.

They do not waste their meted hours, 
But men and masters plan and build:
I see the crowning of their towers,
And happy promises fulfill'd.

And I – perhaps if my intent
Could count on prediluvian age,
The labours I should then have spent
Might so attain their heritage,

But now before the pot can glow
With not to be discover'd gold,
At length the bellows shall not blow,
The furnace shall at last be cold.

Yet it is now too late to heal
The incapable and cumbrous shame
Which makes me when with men I deal
More powerless than the blind or lame.

No, I should love the city less
Even than this my thankless lore;
But I desire the wilderness
Or weeded landslips of the shore.

I walk my breezy belvedere
To watch the low or levant sun,
I see the city pigeons veer,
I mark the tower swallows run

Between the tower-top and the ground
Below me in the bearing air;
Then find in the horizon-round
One spot and hunger to be there.

And then I hate the most that lore
That holds no promise of success;
Then sweetest seems the houseless shore,
Then free and kind the wilderness.

Or ancient mounds that cover bones, 
Or rocks where rockdoves do repair
And trees of terebinth and stones
And silence and a gulf of air.

There on a long and squared height
After the sunset I would lie,
And pierce the yellow waxen light
With free long looking, ere I die.
