Thunderstorm, Instantaneous Forever

After this the halt and summer
Parted company; and taking
Off his cap at night the thunder
Took a hundred blinding stills.
Lilac clusters faded; plucking
Off an armful of new lightnings,
From the field he tried to throw them
At the mansion in the hills.
And when waves of evil laughter
Rolled along the iron roofing
And, like charcoal on a drawing,
Showers thundered on the fence,
Then the crumbling mind began to
Blink; it seemed it would be floodlit
Even in those distant comers
Where the light is now intense.
