No. 10. FOURTH BITUMINOUS DISTRICT. 329
found good in some parts and not so good in the other parts. An
electric haulage plant has been put in operation during the year.
Glen Fisher.—Was idle during the entire year.
St. Mary's Mines.—The general condition of each of these mines is
fair.
Shawmut Mines Nos. 1 and 2.—The general condition of both mines
was fair in regard to ventilation and drainage. In No. 1, I measured
1(5,500 cubic feet of air passing per minute, which is well distributed
throughout the workings. In No. 2, I measured 15,J)00 cubic feet of
air passing per minute, which is also well distributed.
Mead Run Mines Nos. land 2.—These mines are in much better condition
than formerly. The ventilation has been considerably improved
by the erection of stopijings and doors to conduct the air
current around the working places. More attention is being given
to the requirements of the law with the result that better conditions
exist throughout the entire mine.
Shawmut No. 4.—This is a new opening made during the year.
Shawmut No. 8.—This is a new opening which was made about the
beginning of the year and is equipped with mining machines of the
Harrison type.

County Mines.
Coal Glen Mines, Nos. 2 and 3.—The general" conditions of these
mines has been very good during the year. Another drift is being
opened into the lower vein, which looks very favorable at present.
The coal is four feet eight inches in height. This makes the second
opening to this vein. The ventilation is now produced by a Clark
fan five feet in diameter. A larger fan is being erected, which will
be driven by a twenty-five horse power gas engine.
Kurtz Mine.—This mine was not in operation when last visited.
Walston No. 1.—Mine not in operation when last visited.
Walston Nos. 2 and 3.—These mines are in good condition. Everything
is being done to keep them in a healthful and safe condition.
They have put in a new haulage engine, and sunk a shaft near theface
of the workings for drainage and ventilation. They are building
a very large washer for preparing coal for coke, which will soon
be completed.
Brock Mines.—These mines are not in the best condition. The
drainage and ventilation need improvement. The management oi
these mines was changed on the first of this year and it is hoped tha^
better results will follow soon.
Adrian Mine.—The (juantity of air in circulation in this mine when
last measured was 129,000 cubic feet per minute, which was being
fairly well distributed throughout the workings. On some occasions
considerable volumes of explosive gas are encountered in the seventh
