every person employed therein ; provided, that in the case of
old workings when the Mine Inspector shall deem it impracti-

each man, then he may reduce it to eighty feet per man per
minute for such old working.

Section 209 H of Article 1 and Section 164 G of Article 12-
It shall be the duty of the mine foreman to see that proper
cut-throughs are made in all the rooms and pillars at such
distances apart as the Mine Inspector may deem requisite, not
more than thirty-five yards in any instance for the purpose of
ventilation, and the ventilation shall be conducted through
said cut-throughs into the rooms by means of check doors
made of canvas or other suitable material, placed in the
entries or other suitable places, and he shall not permit any
room to be opened in advance of the ventilating current.
Should the Mine Inspector discover any room, entry or other
working places being driven in advance of the air current, or
shall discover any cross-cut or cut-through not properly closed
or bratticed contrary to the requirements of this section, he
shall order the workingmen working in such places to cease
work at once until the law is complied with.

to be made.

One year after the passage of this Act, every mine employ-
ing more than seventy-five persons must be divided into two
or more districts, and each district shall be provided with a
separate split of pure air and the ventilation shall be so
arranged that not more than seventy-five persons shall be
employed at the same time in any one current or split of air ;
provided, that a larger number, not exceeding one hundred
and thirty may be allowed by the Mine Inspector when, in
his judgment, it is impracticable to comply with the fore-
going requirements.

To be divided
into
districts.

In all mines the doors used in guiding and directing the venti-
lation of the mine shall be so hung and adjusted that they
will close themselves, or be supplied with springs or pulleys, so
that they cannot be left standing open, and an attendent shall
be employed at all principal doors through which cars are
hauled, for the purpose of opening and closing said doors when
trips of cars are passing to and from the workings, unless an
approved self-acting door is used, which principal doors shall
be determined by the Mine Inspector or mine foreman. A
hole for shelter shall be provided at each door, so as to protect
said attendant from being ran over by the cars while attending
to his duties, and persons employed for this purpose shall at
all times remain at their post of duty during working hours ;

How doors
shall be bung.
