and lowering them with the hoisting engines.

The hoisting speed is therefore slower, and as less engine power is required for a given load the cylinders.

The possibility of hoisting and pumping from great depths has been discussed, and it remains now to consider the other conditions which will tend to limit mining operations in depth - namely, increase of temperature and increase of rock pressure.

Hoisting engines are provided with powerful brakes and frequently with reversing gear.

Tanks operated by the main hoisting engines, and of capacities up to 50o gallons or more, are applicable under several conditions: (1) When the shaft is deep, the quantity of water insufficient to keep a pump in regular operation, and the hoisting engine not constantly employed in raising mineral, the tank is worked at intervals, being attached temporarily to the hoisting rope in place of the cage.

A mine should always be opened by drift or entry if practicable, as thereby the expense of hoisting and pumping is avoided.
