The sign to remind us
that caution is called for
whenever the towpath
is shin-deep in water,

to warn us the might
of the river might
wash us away,

was washed away.

Part was caught fast
in a branch below water,
submerged till the flood
surged downstream

to a town where one half
of a sign to save lives,
urging care, might emerge
from the waves:
