Blowing house at Dry Lake

Historic England's scheduling record (list entry 1002609) describes a tin mill on the north bank of Dry Lake, close to its junction with the River Erme. It is a small rectangular drystone building up to 5.5 metres long by 3.8 metres wide inside, terraced into the slope. The walls survive unevenly, up to 0.7 metres wide and 1.9 metres high but much lower in places. It lies in the parish of Harford.

The east end of the north wall is thicker and may be slightly raised to carry a launder taking water to the wheel pit, which survives as a buried feature. A leat leads towards the building from several hundred metres upstream on the Erme. A mortar stone found in the bed of the Erme some way downstream is thought to have come from this building, but no mould or mortar stones are visible in or around it now. The mill lies within a large area of tin working.
