from 'Bat' -D H Lawrence

And you think:
'The swallows are flying so late!'

Swallows?

Dark air-life looping
Yet missing the pure loop . . .
A twitch, a twitter, an elastic shudder in flight
And serrated wings against the sky,
Like a glove, a black glove thrown up at the light,
And falling back.

Never swallows!
Bats!
The swallows are gone.

At a wavering instant the swallows give way to bats
By the Ponte Vecchio . . .
Changing guard.

Bats, and an uneasy creeping in one's scalp
As the bats swoop overhead!
Flying madly.

Pipistrello!
Black piper on an infitesimal pipe.
Little lumps that fly in the air and have voices indefinite,
wildly vindictive;

Wings like bits of umbrella.

Bats!

Creatures that hang themselves up like an old rag, to sleep;
And disgustingly upside down.
Hanging upside down like rows of disgusting old rags
And grinning in their sleep.
