30. Each of such district mine inspectors shall be as-
signed by the Bureau, and at need reassigned, to a pre-
scribed inspection territory. The districts, covering the
mining area of the State, shall be divided and from time
to time redivided so as to be approximately equal in extent
of labor and expense of inspection imposed upon each of
such district mine inspectors. Each of such inspectors shall
reside within the territory to which he may respectively
be assigned. Each of such inspectors shall devote his
entire time to the duties of his office, and shall have no
interest, direct or indirect, in any mining operation or
mining investment in this or any contiguous State.

33. It shall be the duty of every district mine inspector not
less frequently than six times in each year in the case of
mines engaged in continuous operation and in the case of
mines not engaged in continuous operation at least once
every two-month period during operation, to enter into and
thoroughly inspect every working place and other excava-
tion, machine, facility and process and all outside works,
ways and plants of every coal mine in his inspection district
or to which he may be assigned, to see that the mine laws
and regulations are strictly observed and carried out; and
at need to make additional visits to such mines to investi-

inspection or investigation may be made at any hour, but
not so as to impede unnecessarily the proper working of
such mine. The inspector shall immediately after each
visit make out a report in triplicate, one copy to be for
the operator to be by him posted under glass for thirty days
at or near the principal mouth of the mine, convenient for
observation by employees, and to be preserved there-
after for one year; one for the Chief Mine Engineer; and
one to be retained by the district mine inspector. Such
report shall state the conditions found in every part of
the mine, in detail; and may include suggestions and rec-
ommendations looking toward improvement of conditions
and better law observance; and shall especially bring to
the attention of the operator or any other person concerned,
and be notice to them and any of them, of any instance of
violation of law or regulations observed, at, in or about
such mine, and such report shall include a statement by
the District Mine Inspector setting forth the number of
persons employed in or about the mine and whether or not
the operator has complied with the law providing work-
men's compensation insurance for all such employees, and
if the operator is a self insurer, the inspection report shall
contain the number of his certificate and further if he is
