Note 227 — Chapter XIV · THE PONDS AND WATER-WORKS.

So called because formed of the united streams which supplied the city and suburbs with clear, sweet, and wholesome water in the west part, whose first decay was owing to certain mills erected thereon by the Knights of St. John, and by degrees gave it the name of Turnmill Brook, which name is still preserved in Turnmill Street, through part of which it took its course. In time this name was lost in that of Fleet Dyke or Ditch.
