Work on this shaft began in August
1836. The shaft worked below the adit level so pumps were installed.
These were powered by a water wheel and the remains of the wheelhouse
can be seen near by. This wheel house was rebuilt and refurbished
in 1865. In the side of the shaft is a short tunnel where the pump
rods entered the shaft. The angle bob which transferred the horizontal
motion of the rods from the water wheel into vertical motion in
the shaft still survives.
