The machinery used in the mines is of the best and latest pattern; the electrical power station gives just under 1,000 h.p.; and the water is pumped out of the mines by a treble ram pipe, which discharges 600 gallons of water per minute at the surface, from a depth of nearly 800 feet.
There are 8,315 persons working in the mines — 6,406 below and 1,909 above, and during the two past years 38 fatal accidents have occurred.
