Full description

RCHME, CITING GREEVES, Untitled Source (Migrated Record). SDV217661.

Sx60147327. Smelting house?about 1797 a smelting house and stamping mills were established on the banks of the stream below bachelors hall tin mine. Between 1798 and 1804, 223 blocks of tin (approximately 27 tons) were produced (rchme, citing greeves).

Untitled Source (Migrated Record). SDV217662.

Relics of the old mine are scant but include the leat from blacka brook which flowed over its final stretch to the launder beside a newtake wall, the bank of the hedge forming its right bank; the launder over-shot the wheel, and beside the pit are the stamping-floors and some blocks of worked masonry.

North of the farm sheds (of bachelors hall) and middle adit is the remains of a building which could well have been the smelting-house erected by mr gray. On the opposite side of the stream is a solidly built embankment high enough to have conducted water via an aqueduct into or beside the house. A leat is easily traced from the embankment to the ford on the stream below the farm sheds. Still further down-stream is the site of the stamping-mill with a wheel-pit and levelled area for the stamps. The leat to it runs beside the wall on the bank above and can be followed as far as ockery (sic) (rchme, citing hemery and 'follow the leat'). Vis=24/4/1989 (rchme) sx60137372. The ruins of a substantial building lie along, and are set into, a fairly steep e slope ("a" on plan). It measures 20.5m by 7.8m, the crumbling coursed mortared walling composed of boulders and stones is 1.1m wide and now up to 2.1m high. The interior, sub-divided into three rooms, and covered by debris is very overgrown. A strong dam ("b") which crosses the shallow stream-valley extends from the se corner of the building. It is 21m long with a 1.9m high, 1.8m thick coursed wall on the lower side and an earthen bank 3.8m to 5m wide on the upper side. It is breached and the effaced section, adjacent to the building, may have once contained a sluice or even a waterwheel. The origin and function of the building is not discernible from the visible evidence however coupled with the dam it clearly had an industrial use. Whether it was a smelting house or a corn mill, later converted to a naptha works is debatable. The dam is not, as recorded, an embankment for an aqueduct and the leat is in fact a by-pass channel which takes water from the stream near bachelors hall, skirts the e side of the dam and empties into the blackbrook beyond the coursed field wall. Vis=one of the recorded stamping mills lies upstream at sx60167345; and the documentary evidence suggests that the site of a second stamping mill occupied the level stances at sx60147375, downstream from the building. Two stances cut into the steep e slope and separated by an eroded gully are 13m by 4.2m and 11m by 5.8m respectively; the uphill sides are crudely edged by large boulders and notably there are a number of large rectangular dressed granite blocks "lying about". The eroded gully might be the site of a wheel-pit however there is no trace of masonry nor leats either entering or leaving the area. The alleged leat to the w along the hedge/wall is almost certainly an erosion gully extending from a hedging ditch; the leat which is alleged to feed this channel can clearly be traced continuing beyond the hedge line into the inbye. Vis=the footings of a possible store or barn lie across the stream at sx60177375. It is 11m by 5.1m and the walling of boulders, stones and upright slabs is now 0.6m wide and 0.6m high; the e side is overlain by a 1.2m high enclosure wall (probert).
