No lease issued under the authority of this chapter shall be
assigned or sublet, except with the consent of the Secretary of the
Interior. The lessee may, in the discretion of the Secretary of the
Interior, be permitted at any time to make written relinquishment
of all rights under such a lease, and upon acceptance thereof be
thereby relieved of all future obligations under said lease, and
may with like consent surrender any legal subdivision of the area
included within the lease. Each lease shall contain provisions for
the purpose of insuring the exercise of reasonable diligence,
skill, and care in the operation of said property; a provision that
such rules for the safety and welfare of the miners and for the
prevention of undue waste as may be prescribed by said Secretary
shall be observed, including a restriction of the workday to not
exceeding eight hours in any one day for underground workers except
in cases of emergency; provisions prohibiting the employment of any
child under the age of sixteen in any mine below the surface;
provisions securing the workmen complete freedom of purchase;
provision requiring the payment of wages at least twice a month in
lawful money of the United States, and providing proper rules and
regulations to insure the fair and just weighing or measurement of
the coal mined by each miner, and such other provisions as he may
deem necessary to insure the sale of the production of such leased
lands to the United States and to the public at reasonable prices,
for the protection of the interests of the United States, for the
prevention of monopoly, and for the safeguarding of the public
welfare. None of such provisions shall be in conflict with the laws
of the State in which the leased property is situated.
