Before a more complete description of
the mine itself, we must continue our
account of the appliances used in obtaining the terrific force used against the
indurated gravel. We have seen how

mine, and poured into a "bulkhead-box."
This "bulkhead," at the top of the bank,
from which point the water is drawn
directly for use at the mine, is usually
the point where the hydraulic pressure
begins. Indeed, the water-way is often
