In early 2009 a scheme of recording and surveying began on a length of walling uncovered in woodland close to Moor Pond and on the north side of Papplewick Lane in the parish of Papplewick, Nottinghamshire. It was believed to relate to the water management system that once served a series of cotton mills that were set alongside the River Leen by George Robinson in the late 18th century. Coursed stonework was initially found amongst trees during the clearance of dense undergrowth on an earthen bank rising from about 2-3m back from the pavement. This subsequently uncovered over 13m of wall, revealing the full depth of the feature, the batter or slope of its face, the presence of footings, an overall curving plan and the greater height of remaining rubble corework behind the wall. The wall included a narrow opening that ran back under the corework at least 1.5m. Whilst the west end of the wall was located, the east end still remains covered. Within the opening and extending out beyond the wall there were revealed two lines of iron nails and several long rods, similar to those previously recorded at Papplewick. These were interpreted as support fixtures at the base of timber-built troughs or launders that facilitated the movement of water. The launder’s base level corresponded with the top of what remained of an 18th century brick arch, set on a stone foundation and with an internal width of 4 feet (1.2m). The brickwork had clearly not extended beyond the front of the opening. Below the arch there was evidence for an earlier lower and narrower launder that the arch may have partly protected. The arch had been reduced and the opening narrowed to contain the later 3 feet (0.9m) wide launder set at a higher level. The wall structure supported a bank behind which there was a north-south running leat that ran from north of Moor Pond. The walling on Papplewick Lane and the raised banks and leats to the north and south may relate to the building of the expansionof Grange Mill several years later.
