No. 10. SECOND BITUMINOUS DISTRICT. 279
The capacity of the mine is about 250 tons of coal daily, all of
which is made into coke. The main opening is on a level with the
ovens, which allows the coal to be taken direct from the mine and
charged into the ovens from the mine wagons. A tipple is not
needed. The mine mouth has been neatly timbered with twenty-one
sets of 8x10 inch oak timbers. The ventilation, at present, is produced
by a temporary furnace which will be replaced later by a ventilating
fan.
Thirty-three houses of four rooms each have been built in connection
with the works. The officials are Mr. L. F, Ruth, of Oonuellsville,
general manager, and Mr, Robert Gordon, of Greensburg, superintendent
and mine foreman.

Greensburg No. 2 slope.—On each visit to this mine, I
found the
ventilation and drainage very good; 14,800 cubic feet of air was in
circulation when last measured.
Among the improvements contemplated at this mine are a new set
of haulage engines, that are now on the ground and in course
of erection, which, when completed, will take the place of the old ones,
that are too small, owing to the development of the mine and the
increased trade. Mine foreman. John Mclntyre.
Arona Slope.—When last examined, the general condition of this
mine was favorable. The quantity of air in circulation was 54,000
cubic feet per minute, well distributed to the various working places.
The drainage on the north side of the mine was very good, but on the
south side it was somewhat defective. The water course in that part
is almost on a level with the creek bed, and the water from the creek,
when it rises, enters that part of the mine.
Among the improvements during the year was the erection of a
ventilating fan. 10 feet in diameter, with blades 0| feet wide, driven
by an engine 10x30 inches, which was built by the Connellsville Machine
and Car Company, of Connellsville, Pa. Mine foreman, William
Nesbit.
Madison Slo])e.—Among the imi)i"V('nients made at this mine during
the year was the changing of the haulage from the old roadway
to a new one. Ky this change, a farthei- point in the mine was reached
by a more direct route. At the time of my last visit, I observed that
in some of the entries the velocity of the air current was not sufficient
to keep the workings free from smoke. This was caused by changing
the haulage, which inteifcivd with some of the doors and brattices
