Description of Mines.
Bessie.—This mine is in good condition, and is being well looked
after. Considerable developments have been made during the year.
Two new overcasts were built, which carry the ventilation well up to
and around the working places. Mining boss and superintendent,
George Whyel.
Berlin.—This mine has not employed a sufficient number of persons
to bring it
under the provisions of the law at any period during the
year.
Casselman.—The air current in this mine is not vigorous enough to
properly ventilate the workings. Ventilation is produced by the
radiation of heat from steam pipes, which enter the slope to supply
steam to a hoisting engine underground, and also to the mine pumps.
The motive column produced by this heat is not large enough to
give sufficient power to overcome the resistance of the mine, hence,
the air current is feeble and sluggish, and the powder smoke hangs
in clouds in the working places. I have repeatedly called the attention
of the mine superintendent to this condition of affairs, and
he has just as repeatedly promised to remedy them, but as yet these
promises have not been fulfilled. The mine boss has done all in his
power to conduct a current of air up to and around the workings, but
it unable to accomplish it simply because there is not power enough
in the ventilating force. What is needed is a fan placed over the
inlet shaft.
Mining boss, John Connor,
Cumberland.—This mine has been very much improved in its condition,
being very rapidly developed into new territory, where a good
system of mining has been adopted. The old work has all been
exhausted and the new work is well ventilated on the double entry
system, and the mine is well looked after as to healthfulness and
safety. A new chute has been built during the year, which improves
