underneath Kentish Town
the fine Fleet flows down
sneaking out dammed ponds
slidden across the thistled Heath
the source that took relief
hidden, next to Anglers Lane
a vanishing of oyster shells
flicked by idle ghosts of fishermen
who spit a murmured gargle
deep below in sewage world
a water's roar
silenced to hush
by the concrete poured
over centuries of bricks
