The direction of air currents in
the natural ventilation of mine is
determined by the relative weight of
two columns of air. One may be in
shaft, the other outside, or there
may be two shafts connected below
their mouths having different eleva-
tions. During the day the air in
the shaft and level, being colder
than the outside air, has tendency
to fall and the deeper shaft becomes
a"down cast" At night the outside
air may become cooler than that in
the mine, and the shorter shaft be-
come down cast" At a time
when the mine air and that outside
have about the same temperature
and density the ventilation of the
workings becomes poor, az the air
currents are almost at standstill.
1t is for this reason that the smoke
often hings in mine workings when
shots arr fired in the early evening,
or about sunrise in the morning,
when th, air currents are sluggish.
Shots fled at midnight or at noon
in the sane working will usually
clear away rapidly, except on days
wien he atmospheric conditions
render the temperature in the mine
and oltside about equal.
The bessemerizing of copper

lshed by blowing air into the molten
matte which has been drawn from
