ME. F. Z. SCHELLENBERG—The furnace acts by
the heating of a column of air, and the higher
that column is. the greater the motive power.
MR. SAMUEL DIESCHER—It is rarifying the air in
the column.
MR. F. Z. SCHELLENBERG—I will take a short cut
and say that to my mind the right way to ventilate
an ordinary mine is to open up to the fresh
air as many places as practical and draw out at
at one place with slow speed. )ou may draw
out very slowly if you have a good many fresh air
openings.
MR. SAMIEL DIESCHER—There must be a difference
in that. The pressure produced must be
greater by powerful fans than by a furnace.
MR. WILLIAM CLIFFORD—The furnace is more
economical in deep mines than in shallow ones.
MR. SAMUEL DIESCHER—Suppose you make a
mine fan as large as there was ever one built,
how much of a furnace wou'.d it take to produce
an equal ventilation?
MR. WILLIAM CLIFFORD—Murton colliery furnaces
probably use as much coal as would be needed to
run ten of the largest fans in Pennsylvania.
MR. F. Z. SCHELLENBERG—You see at our depths.
that we have here, ordinarily the temperature is
about fifty-six degrees Fahrenheit. That is about
the average temperature of the air outside here
and is about the temperature of spring water. It
is the temperature of our shallow mines wdien
they are ventilated. Of course, if (he air is stagnant
in the mine, it gets warmer, but the condition
we do not have here is of great depths where
for every sixty, or eighty, or a hundred feet,
another degree Fahrenheit is added and there is
greater disposition for ascension. Ascensional
ventilation is natural ventilation that we can
take advantage of in aid of a machine or a furnace,
but with the vicissitudes of the seasons there
is baffling and reversing of natural draft. Now
in deep western mines, where explosive gases are
not made, it is all natural ventilation.
In the history of this matter, tnere was a time
not very long ago when a mine was run without
the use of steam power. Then we built the furnaces
as we had no need of steam power for other
purposes. Now we are at the stage generally
where steam is required, and of course we naturally
put in the fan. Besides that, the fan is undoubtedly
the best macnine for shallow mines,
and we are not contemplating any such very deep
mines as they have in England.
Commencing November 7th, the Missouri Paciffc Ry.
Will operate semi-weekly Tourist Car Service between
St. Louis and Los Angeles, via the San
Pedro Route. The cars will leave St. Louis every
Tuesday and Thursday at 9:00 A. M.
PROPERTIES OF BUFFALO
CBi, SUSQUEHANNA CO.
Dealing with its coal properties the annual report
of the Buffalo & Susquehanna says: "In the
last annual report reference was made to the acquisition,
by the Buffalo & Susquehanna Coal &
Coke Co., of a large tract of coal in the Plumville
region. Since that time additional purchases of
adjoining land and mining rights conservatively
estimated to contain 14,000.00(1 tons of excellent
bituminous coal have been made. Further options
are now held on considerable land and mining
rights in the Plumville field, the larger part of
which will probably be acquired. With the completion
of the purchases now contemplated it is
conservatively estimated that the Buffalo & Susquehanna
Coal & Coke Co. will own coal lands containing
about 120,000,000 tons of coal. This does
not include the lands estimated to contain 25,000,-
000 tons of coal owned by the Powhatan Coal &
Coke Co. With the completion of the plants at
Plumville and Big Run the annual capacity of all
the plants of the Buffalo & Susquehanna Coal &
Coke Co. will be about 2,500,000 tons; that of the
plants of the Powhatan Coal & Coke Co. will be
in excess of 250,000 tons, and that of other shippers
tributary to our line should not be less than
250,000 tons. This makes the annual coal and
coke tonnage that should pass over the lines of
the Buffalo & Susquehanna railroad about 3,000,-
000 tons. In time this tonnage should be largely
increased by the development of properties, owned
by other operators, that will naturally be tributary
to our road."
LITTLE KANAWHA PROPERTY SOLD.
The Little Kanawha syndicate's property has
finally been turned over to the Pittsburgh
& Lake Erie Railroad Co. in New York
October 28. This disposes of the project in a
manner not foreseen when the enterprise started,
but will serve the same end in giving to Pittsburgh
an additional outlet to tidewater and making
an aggressive campaign for export trade the
more feasible on that account. It also forms a
new 'Lake to Seaboard" route. The'plans of the
Pittsburgh & Lake Erie, probably in conjunction
with the Pennsylvania, provide for a scheme of
new construction which is the largest undertaken
in many years in trunk line territory. An expenditure
of many millions of dollars will be required
to carry out this plan, which involves a
new railroad from West Economy, 20 miles west
of Pittsburgh, to Staunton, Va.. where connection
will be made with the Chesapeake & Ohio railroad.
Over this railroad the seaboard will be reached at
Newport News, where the C. & O. has magnificent
terminals, built during the regime of Collis P.
Huntington.
