Section of grid iron character unit (HSY 2045) in order to show the probable site of the Blythe Wheel (see SMR PRN 3495 and Crossley 1989, p107). This mill is known from a Fairbanks map of 1741 which places it to the south of a 'Ladies Spring' and Spring Meadow, the shapes of which can be traced on later OS maps. Crossley et al (1989) found references to this mill from 1739-41 however Kingston (2004 Chapter 5 note 1) has traced references in the Norton Parish Registers from 1723-1775. The mill building seems to have outlived the associated goits and dam and is probably the 'Rushdale Cottages' shown on the 1891 Yorkshire 25inch OS. A path to the east of these cottages may mark the route of the head goit. Nothing visible on the surface at present, although archaeological remains may survive underground. Grid iron terraced housing built between 1891 (lower end of Valley Road already present by 1891) and 1905 (by which time all of the streets within this polygon had been laid out on a grid iron pattern the principal streets of which follow the southern side of the Meersbrook valley. 1877 25 inch Derbyshire OS shows this area as enclosed land lying between the hamlet of Norton Lees, Meersbrook Park and the Meersbrook.
