Truth

How the devil do I know
if there are rocks in your field,
plow it and find out.
If the plow strikes something
harder than earth, the point
shatters at a sudden blow,
and the tractor jerks sidewise
and dumps you off the seat—
because the spring hitch
isn’t set to trip quickly enough
and it never is—probably
you hit a rock. That means
the glacier emptied his pocket
in your field as well as mine,
but the connection with a thing
is the only truth that I know of,
so plow it.
