London was a steeper place

Listen, you let a secret river out
since then it slips on tarmacadam
serpentine besides the ursine bros
glistens down the Kingsland road.

“Look at London's valleys cowed
Us and Vs made moot by pipes
moved, I let those rivers out.”

You must have dug out layers of road
– and how many bones?

“Sequin wet ribbon
that twists on road
a fleet footed river -
      burn in the city!
Surely a wonder
worth my effort.”

Then I'll take a victory drink.
Is that champagne you're necking?
From a broken water main.

“Sit here, take a sip. Watch.
See the capital, those
eroding banks contained -
seep, and wane, and rinse
away.”
