of tinners was thus engaged in the bottoms, the chief miners (called
Captains) took the bearing of the lode with a well-approved needle
(which they call dialling the ground), and funk another fliaft at B,
as more convenient for getting at the lode at Z, and neceffary to give
air to the workmen, and draw the water, lode, and deads from the
workings below at P and ibmetimes there are'three mafts or
more finking on the lode at one time. Whilft the fliaft B is defcend-
ing to P £, tire bottoms are carried forward in a ftep-like manner,
wherefoever the lode invites, and the water permits; § It will occur
to the intelligent, reader, that the fiflhre being cleared1 of lb much
ore, many vacancies in the mine muft enlue; in thefe vacancies by
pütting timbers brofs the fiflure like beams, and laying planks of
