You divide the circumference
by the diameter
of so many things:

A hubcap left on the side of the road.

The green inside
a traffic light that swings
in the wind ahead. The red
and yellow ones too.

Another utility hole cover.

The rooftop to a bluebird
nest box in the prairie.
The base of a street lamp
up the hill. The cut
log from a poplar tree.

And the circumference
of the reclaimed
permanently muted
bronze bell
in that “For Whom”
sculpture you pass
each time
in search of
a perfect circle.
