This pattern of drainage and subdivision of this land changes significantly between its mapping in 1851 and 1891. The 1851 arrangement closely matches that shown on the 1825 enclosure plan (Haywood 1825). The presence of a large number of enclosures on this map labelled 'Participants Land' (and not marked with the characteristic 't' marks which show the responsibility for laying out new hedges on this plan" suggests that this land was first 'improved' as a part of the drainage of Hatfield Chase by Vermuyden in the early 17th century. ['Participants' was the term given to the early 'venture capitalists' who funded Vermuyden's drainage of Hatfield Chase in exchange for land - an analogous group to the fenland 'Adventurers']. The changes to the layout of this land by 1891 were principally as a result of the warping system constructed by Makin Durham in the 1850s, and fed by 'Durham's Warping Drain' a large embanked cutting used on spring tides to flood surrounding countryside and deposit silt on the land to improve its fertility (Van de Noort and Ellis 1997, 196). This drain was progressively extended further east and eventually southwards towards the site of Thorne Colliery by 1881 (ibid.) The network of roads and tracks within this area is similar to that depicted by Haywood in 1825 and provides fragmentary legibility of the earlier drained landscape of this area.
