Folly Vein, West and East Levels

Reference to Plan 24 & 25
The West Drift is continued in the vein about 12c 80l or 140fa and there the vein is lost, in the Low Level. But there is a rise about 20fa from the Forefield, communicating with a Top Drift, made in the vein, and which approaches another, continued east in the Green Groves Vein.

The Moor Vein, a little north of the Green Groves Vein, and the Folly Vein, are thought to be the same.

Repair, good, being in constant use.

Eastward the level is driven about 2c 80l or 30fa in the Folly Vein till the Limestone and Vein are lost together.

The Folly Vein has borne well under the level, both east and west of the Main Level. There are at present 6 Partnerships employed under-level, one of them under the East Level, and the rest westward. Most of their workings are somewhat poorer than they were, but they still produce good ore, the greatest proportion of what is raised at the mine. There are about 36 men employed at these workings. The bearing part under-level so far as yet ascertained, extends in length about 100 fathoms, 30 eastward, and 70 westward. Several of the workings are about 20 fathoms below the level.

About 14 fathoms south of the Folly Vein is Dufton String a "fine wick string".
