S. B. J. Skertchly, in The Geology of the Fenland (1877), p. 129, noted that the precise 

 boundaries of the peat and silt were "very obscure, for the peat thins out insensibly 

 along its borders." The limits of the Bedford Levels are taken from Samuel Wells' 

 map of 1829 on a scale of i^ miles = i inch.
