Samuel Preston settled in Stockport, Wayne County PA in 1788. His account of a supposed periodic cycle of flooding of the upper Delaware River is priceless for its detailed observations on farming in the valley. Fellow farmers and informants he references are: John Hilborn, on the Susquehanna, Nicholas Depui, Esq. of Minesink [Monroe Co PA], Joseph Ross of Cosheckton [Cochecton NY] and Erasmus Darwin, grandfather of Charles Darwin. The work first appeared in Memoirs of the Philadelphia Society for Promoting Agriculture: Containing Communications on Various Subjects in Husbandry & Rural Affairs, Volume 4, 1818.
