No. 12.] Fifth Bituminous District. 407
is worked ou the double-entry system. Fan ventilation which has not
been very satisfactory on account of the air not being- carried forward.
November 5, 1891, I measured a volume of 24,000 cubic feet at the fan
and only 7,600 cubic feet in the dip, showing- great loss by leakage. A
new haulage way is being opened into this mine which I hope wdll very
much improve the ventilation. Owing to the unsatisfactory condition
of the mine, I have visited it live times during the year and I think there
is now a fair prospect that it will be put in good order. One hundred
new ovens have been added to this plant making 314 in all. Mining-
boss, David Young-.
Steioart Mine No. 1.—Located on the B. & O. K. B,., near Evans station.
Slope opening, rope haulage and double-entry system. Ventilated by
a Guibal fan 20' in diameter which produced, July 14, 1891, a volume of
74,580 cubic feet with a water gauge of four-tenths of an inch, thus showing
that the airways were large and in good order. The split air current
system is used and ou first flat I measured 17,920 cubic feet. All the
provisions of the mining law are strictly enforced and I consider this
mine one of the best in the region. Mining-boss, I. G. Boby.
Scottdale Iron and Steel Company.—Located at Scottdale, Pa. Drift
opening and for the first half of the year there was natural ventilation,
but in August the air became so bad that they consented to put in a 12'
fan and I am sure that neither the operators nor employes have regretted
it. November 10, 1891, I measured 31,860 cubic feet of air in circulation
which was well distributed to the workmen. The mine is now in good
condition. Mining-boss, Henry Suttle.
Sprhig Grove Mine.—Located on the Dickenson Bun branch of the
Pittsburg-, McKeesport and Youghiogheuy railroad near Vanderbilt.
Owners, Brown & Cochran. Drift opening and natural ventilation.
This is a new mine opened during the year. Preparations are being
made to build a furnace soon. Condition of the mine fair. Mining-boss,
Frank Pickard.
Steivart Mine No. ,"?.—Owned and operated by the Stewart Lon Com-
pany. Drift opening into the Sewickley vein Avhich is about 4| feet thick
and 152 feet above the Connellsville vein. The coal is a little harder
than the big- vein and is of a very fair quality. This mine has two openings,
with considerable difference of elevation and is ventilated by natural
forces. General condition and drainage good. Mining-boss, Charles
Boberts.
Statler and Standard.—Drift openings and natural ventilation which
is not very g-ood. November 25, 1891, I measured a volume of 9,120
cubic feet. This is not enoug-h, as there is a great deal of powder used,
consequently it requires more air. The di'ainage and haulage roads
were in fair condition. Mining-boss, Orlando Flesher.
Snider Mine.—Located on the National pike two miles west of Union-
town. Drift opening and natural ventilation. The production of this
