OUR CORRESPONDENCE.
The Anemometer Impeached.
FRosTBURG, Nov. 25, 1879.

tROSTBURG, NOV. 70, 1879.
Mr.. Editor In your last issue
there appears An article heaoed "a
Dash at Mr.. Riordan's Report" from
your Lonaconing correspondent, "1he
Umbrella Man." Let me congratu-
late your correspondent upon his spicy
and we'll written article. It WAS we'll
received by the readers of the JOUR.
NAL in tho Frostburg mining district,
and assure your correspondent that
q majority of the miners Of this reg
ion do not understand Mr.. Riordan's q
report and would like to have some
explanations on the same points set
forth by him.
But as your correspondent only re-
fers to the mines on Georges Creek
whore the ansmometer has wrought
such wonderful improvements in the
salubrious climate of the mines of
that district, I beg to say thaa inst-n
ment does not seem to havs ha,. Tie
same effect on the venti.asioA u he
mines at the northern end of our coal
basin. Not being versed in Latin
definitions or Greek roots, and not
having twenty-five years experience
as mine conductor and mining engi-
ne er, / cannot account for the diHer-
ence. (Mr. Riordan, please explain.)
find on page Eve that the Borden
Pit has only "a cubic feet per man
per minute by the anemometer. This
was found insufficient for the miners
to work in and new ventilating fur
mace had to be built to properly von-
tilate this mine, although Mr.. Rior-
dan states in his report that tois Pit
was as we'll ventilated as any other
mine in the region. Let me here ask
Mr.. Rio-dan question: If the Bor-
den Pit was as well ventilated as any
other mine in the region what was the
nee Ct the company going to the ex-
pense of building a new ven.ilsting
| furnace? M. Inspector, explanations
are in order.
Then find on another page that
the Na.'oaal rn;ne OF the HamI shire
and Baltimore coal comnany has an
air c;,rrcnt Of 1876 cubic rect per man
! per minute. Now, it i. a well estab-
l;sled fact that the miners in this
mine are half of the time they are
working cboked with black darp.
Exp anstions are in order IN regard
to this mine. Either the thermometer
or new ventilsting furnace is re-
quired.
In the table I find the Consolida-
tion coal company's mines mentioned.
All appear to be up to the standard
of 66 cubic feet per man per minute
vita tie exception of the Ocssn mine,
which is fraction below it. The New
Hope mine has nearly double the re-
quired quantity. If brother Ben
keeps on improving the ventilation of
this mine the miners employed there
in will have to take the advice of your
correspondent, "The Umbrella Man,
to the miners of Jackson mine, and
"look out for their anchor chains" :"
The next in order are the Hoffman
and Pompey Smash mines. There is
| scme things connected with the ane-
mometer Measurement of the air of
these mines that also war. soua ey'
PLANTATION. IL the first pace there is
no "Ponpey Slaash mine, No. shJ
2" as set forth in the Inspectors re-
port. For the Information of your
correspondent, "The Umbrella Man,
ard the readers of the JOURNAL, that
the air was measured on the down
cast air-way and found to register on
the anemcnetsr. according to the re-
port, 1922 cubic feet; it was then
measured at the up-cast shaft and
there the sans number Of feet, 1872,
were found returning. So the read
ers of the JOURNAL will see at a
glance that ths air was measured
ts0sce and Pompey Smash mine credit
ed with double the amount of air
passing through it. If this was the
method adopted at the mines Of
George Creek With their three and
four air-ways, "Ihe Umbrella Man
can easily account for the great gale
blowing through .heir mines. The
Hoffman mine was me assured It the
up-cast and registered on the ane-
nometer 1879 cubic feet. Where
the other 5000 feet were gotten from
is more than I can inform your read
