448 REPORT OP THE INSPECTORS OF MINES. Off. Doc.
Turks.—The ventilatioii produced by a small fui'uace is fairly well
c:onducted through the miue, but the power of the furnace is insufficient
to produce proper ventilation, as it becomes farther extended,
but, owing to the coal area being uncertain, caused by numerous
faults, the company does not feel justified in enlarging it or sinking
a new shaft and building a furnace as was suggested. They have
promised to build a new small furnace near No. 2 opening for the
present emergency. An average of G,900 cubic feet of air was returning
to the furnace. The roads were generally dry. John Baker,
foreman.
Queen, or Leland No. 2.—The average volume of 0,700 cubic feet of
air circulating through this mine keeps the ventilation in very fair
condition for the number of men employed. The main haulage way
Vv'as poorly drained; other places were fair. E. Brubaker, foreman.
Beading.—If the furnace was kept going in "E" seam, this mine
would be well ventilated. A natural current of 3,240 cubic feet was
passing out at the furnace. Roads were generally dry.
''D" seam was poorly ventilated owing to the power of furnace not
being confined to the workings, which defect was caused by imperfect
brattices. On one occasion, I requested the foreman to improve
the condition of brattices, but was informed that it was hard to get
the necessary material, but no such report appeared in his report book.
In December, I
wrote the company that the brattices had been neglected
to such an extent that it would pay them to put in a new shaft
and furnace; also, stating that they had not previously furnished the
necessary material. They replied by stating that the foreman, who
also acts as superintendent, had never asked for any material that
he did not get. I expect that it will be improved in the near future.
C. Maher, foreman.
Sterling No. 2.—Has reduced the force to nine men, so that it
not come under the provisions oi the law.
Sterling No. 3.—On my last visit the ventilation was insufficient,
owing to a large fall in main airway, but previous to that time it was
in fair condition. Drainage was rather deficient on main heading.
An average of 10,375 cubic feet of air was measured at furnace return,
being conducted through the mine in one current. W. Craig, foreman.
Schwinn No. 1.—This mine did not come under the provisions of the
law during the year, employing only a few men.
Schwinn No. 2.—At my request a new shaft has been sunk, and a
furnace was directed to be built, but is not yet commenced. The
ventilation was deficient during the summer months, and when I
directed that some changes be made they reduced the force to nine
men. A sufficient natural current is circulating in cold wcatlK^r.
Hillside, formerly Steiner.—Has not come under the provisions of
