Pot Black! Sarah tries her hand at being a chimney sweep's assistant when she joins Dodd Diggins of Framlingham in Suffolk. Dodd has been cleaning chimneys with brushes for 50 years and says ' You can keep your modern methods'. The Rev Valentine Fletcher collects chimney pots and his prize exhibits range from 18th-century giants of six feet to mere midgets with fluted edges, which he says are the rarest.
