HER Number:MDV20838
Name:Tin mill close to Dry Lake Ford on the north bank of the Erme

Summary

Blowing house recorded by Greeves (1981) and Butler (1993) and surveyed in 1994 and 2018. Ruined tin mill sited at the foot of the low scarp which defines the eastern limit of streamworks in the Erme valley at its confluence with Upper Dry Lake. The building, with well-built moorstone walls, has been cut into the slope with the eastern wall taking the form of a revetment while the other walls, with the exception of the western side which is ruined to ground level, are embanked. The building is an irregular rectangle of approximately 8.0 metres by 5.5 metres and up to 1.0 metre high. A short leat, with its source 120 metres further up the Erme appears to be associated with the building and the embanked south wall might be interpreted as a leat embankment. Although Newman found no wheelpit during his 2018 survey visit (when the interior was described as being filled with rushes), Greeves records the mill 'appears to have an internal wheelpit. Of particular interest is that it has a dressing floor with two buddle pits on its west side' during his 1984 survey work.

(Visited 10/11/1994) Probable blowing house close to Dry Lake Ford on the north bank of the Erme at SX 6337 6636, at the edge of an area of streamworks. Both Greeves (1981) and Butler (1993) note this site as a possible tin mill.
The building measures 6.0 metres north to south by 5.4 metres; its walls, of coursed granite blocks, are 1.3 metres wide and 0.8 metres high. A low scarp forms the south wall. There is no obvious entrance. In the north-west corner is a rubble filled pit, 3.8 metres long and 1.2 metres wide, this is probably the remains of the wheel pit. Close to this, set in the north-west corner, is a probable hearth, 1.0 metre wide and 0.7 metres deep. A dry leat channel, 1.0 metre wide and 0.6 metres deep, runs for some 70 metres north of the building.

SX 263373 66371 A possible ruined tin mill sited at the foot of the low scarp which defines the eastern limit of streamworks in the Erme valley at its confluence with Upper Dry Lake. The building, with well-built moorstone walls, has been cut into the slope with the eastern wall taking the form of a revetment while the other walls, with the exception of the western side which is ruined to ground level, are embanked. The building is an irregular rectangle of approximately 8.0 metres by 5.5 metres and up to 1.0 metre high.
A short leat, with its source 120 metres further up the Erme appears to be associated with the building and the embanked south wall might be interpreted as a leat embankment. However, no wheelpit or associated artefacts have been recorded at this site. The interior is currently filled with rushes.

Upper Dry Lake tin mill. Although suggested by Newman in his 2018 survey report as a doubtful mill, Greeves offers the following in support of the identification:
Visited 02.06.1976. Planned at 1:100 by Greeves and Robinson 31.08.1984. The mill appears to have an internal wheelpit. Of particular interest is that it has a dressing floor with two buddle pits on its west side.
