Edward Estlin Cummings - when serpents bargain

when serpents bargain for the right to squirm
and the sun strikes to gain a living wage -
when thorns regard their roses with alarm
and rainbows are insured against old age

when every thrush may sing no new moon in
if all screech-owls have not okayed his voice
- and any wave signs on the dotted line
or else an ocean is compelled to close

when the oak begs permission of the birch
to make an acorn - valleys accuse their
mountains of having altitude - and march
denounces april as a saboteur

then we'll believe in that incredible
unanimal mankind (and not until)

Edward Estlin Cummings
