Sparks fly in this description of one of the gardening rites of autumn, though Laurence Binyon offers a rather dark view of purging and renewal in the human scheme of things.

Perhaps there is a lightening of tone in his last line: “Nothing is certain, only the certain spring.” Binyon will always be associated with his Remembrance Day poem, For the Fallen. 
     
THE BURNING OF THE LEAVES
                   `        
Now is the time for the burning of the leaves.
They go to the fire; the nostril pricks with smoke
Wandering slowly into a weeping mist.
Brittle and blotched, ragged and rotten sheaves!
A flame seizes the smouldering ruin and bites
On stubborn stalks that crackle as they resist.

The last hollyhock’s fallen tower is dust;
All the spices of June are a bitter reek,
All the extravagant riches spent and mean.
All burns! The reddest rose is a ghost;
Sparks whirl up, to expire in the mist; the wild
Fingers of fire are making corruption clean.

Now is the time for stripping the spirit bare,
Time for the burning of days ended and done,
Idle solace of things that have gone before:
Rootless hopes and fruitless desire are there;
Let them go to the fire, with never a look behind.
The world that was ours is a world that is ours no more.

They will come again, the leaf and the flower, to arise
From squalor of rottenness into the old splendour,
And magical scents to a wondering memory bring;
The same glory, to shine upon different eyes.
Earth cares for her own ruins, naught for ours.
Nothing is certain, only the certain spring.
