No. 10. SEVENTH BITUMINOUS DISTRICT. 403
Beck's Run.—This mine was not in operation during the year.
Ormsby.—The general condition of this mine is satisfactory. Average
quantity of air passing near the face of the different butt entries
is about 9,000 cubic feet per minute, and 50,000 cubic feet at the
furnace upcast shaft. The coal is mined by hand labor, and the
hauling is done, partly, by steam locomotive and partly by the head
and tail rope method. There are about seven miles of wire rope
connected to the haulage plant. The coal in this mine is of excellent
quality and is

Quantity of air passing at the
furnace, 23,000 cubic feet per minute, and the quantity passing near
the face of the workings varied in the different entries from 4,000 to
9,000 cubic feet per minute. The mine is worked by the single and
double entry systems. The coal is mined by hand labor and it is
hauled from the mine by animal powder.
Knoxville and Rankin.—The coal produced at these mines is used
for domestic purposes. At the time of my last visit there were not
a sufficient number of persons employed in either mine to bring them
under the provisions of the law.

First Pool Nos. 1 «nd 2.—Both the double and treble entry systems
of working are adopted at these mines. The coal is undermined by
the use of mining machines, of the Harrison type. Haulage is done
by the head and tail rope system. Vetilation is produced by a 2.5-foot
Vulcan fan. The same fan ventilates both mines. The workings are
at all times kept in a safe, healthful condition as far as possible.
The quantity of air passing at the outlet, when last measured, was
90,000 cubic feet per minute, which is well distributed to the working
parts of the mine.
Lick Run.—When last examined was in reasonably good condition,
excepting that one of the butt entries was driven too far in advance
ci the air current. Quantity of air passing at the inlet, 18,800 cubic
feet per minute, and from 6,000 to 7,000 cubic feet is circulating
through the various butt entries. The coal is mined by hand labor;
haulage is done by a steam locomotive, and a 10-foot Brazil fan is
used to produce ventilation.

condition. Quantity of air near the face of the workings, as measured
in the different entries, varied from G,000 to 14,000 cubic feet per
