h shall be carefully
examined once each twelve hours. Not more than four persons shall be
lowered or hoisted in or on a bucket at one time, and no person
shall be permitted to ride on a loaded bucket. The bucket used in
lowering or hoisting persons shall be equipped with proper safety
devices, so that same cannot become detached from the rope or cable,
and cannot tip or turn upside down while being so used. The chief
inspector of mines, and the district inspector of mines, shall have
jurisdiction over such mine when the shaft or slope reaches a depth
of twenty-five feet, and such person, firm or corporation shall
comply with any order issued by either or both of them with respect
to the safety of persons employed. Other than the provisions herein,
the provisions of this act shall not apply to the opening of a mine
until such opening reaches the seam, and the entry or landing be
extended beyond a breakthrough, or other place driven at right
angles thereto. (Penalty, Sec. 976.)

Sec. 950. [=Additional openings; when and how provided for.=] When
in the opinion of the district inspector of mines together with the
chief inspector of mines, the ways and means of egress in any mine
under their jurisdiction, from the interior working places to the
surface, as provided for in this act, are inadequate as a safe and
ready means of escape in case of probable emergency, and there are
extra hazards of a permanent nature that cannot be removed either
from long distance from the interior working places to the exterior
openings for egress, from danger of fire at any point, or any other
cause that probably will result in the entombment of persons working
therein, they shall jointly give notice in writing to the owner,
lessee or agent of such mine, and require an additional opening by
shaft, slope or drift, from the surface; the location of the
interior end of such shaft, slope, or drift, to be sufficiently near
the interior working places in that part of the mine where such
persons are endangered, to afford such persons safe and ready means
of escape, free from such hazards. (Sec. 932; Penalty Sec. 976.)

=RELATING TO SUPERINTENDENT, MINE-FOREMAN AND OVER-SEER.=

Sec. 951. [=Duties of superintendent.=] The superintendent in charge
of a mine shall see that the provisions of this act are carried out,
and shall, in case of an accident resulting in the death of or
injury to persons, carefully investigate such accident, and report
