Littl Salting
From Riddley Walker Annotations
Seasalter TH, a north Kent town which, as its name suggests, was a long-time center of salt harvesting: seawater was collected there in tidal troughs called salt pans, where it evaporated at low tide leaving the salt. Later a seawall was built to reclaim the lowlands for farming, but in Riddley's time the sea has probably taken back most of the land. Seasalter has also been known for illicit shipping operations and archeological discoveries.
