Uses of tho barometer and Their
mometer as they pertain to coal
mining were explained at The Fair
mont mining extension school last
evening at the Faifmont High
school annex When the second les
son IN ventiiatton was taken up.
Gales that blow against one
when Walking and the fact that
warm air arises from d lamp while
tho cold air rushess in below to
rcstore edui ibribm hdtcates clear
" that air has weight and conse-
quenas pressure Is present. The
barometer Is an instrument used
10 determining the pressure Of the
atmospheric. The rule laid down
70 ind the pressure OF the atmos-
phere. The rule laid down to find
he pressure Of the atmosphere to
take the Weight Of "a cubic inch Of
mercury times the barometric
reading in inches!
Barometric pressure applies 10
mining IN that when the pressure
decreases radically II gives warn
Ing OF the expansion OF the volume
Of gaaes IN the event Of such a
dow explosions may occur. In
many countries Il is necessary to
make barometric readings daily.
Next the study Of the thermo-
meter and It's application TO min
Ing was taken up, this instrument
beins used 70 measure the temper
ature. Details 81 the principles Of
the Fahtenheit and Centigrade
scales were explained. Uses Of.
Inc thermometer as applied to min
ing might be summed up as fol-
lows: To Determine the relative
humidity; To- determine the tenn
perature Of heating gobs; to deter
nine the Temperature of sealed
areas. Rising Temperatures In
dealed areas indicate OF course that
