Turning northwards again from the centre of England, in Rutland the old three-year course of two crops and a fallow was universal in the unenclosed parishes;[26] in Lincoln two, three and four-field systems were practised;[27] the two-field course was also prevalent in Yorkshire.[28]

A singular practice was followed in the East Riding Wolds. “The greater part of the Wold townships which lie open have a great quantity of out-field in leyland, i.e., land from which they take a crop every third, fourth, fifth, or sixth year, according to the custom of the township.”[29]

In contrast we may mention the Battersea common fields, which were “sown with one uniform round of grain without intermission and consequently without fallowing.”[30]
