The Secretary of the Army, in expending appropriations in the
preparation for and construction of works for the restraining or
impounding of mining debris in the State of California, is
authorized to enter into an agreement that the contractor shall
look solely to the State of California for one-half of such
expense, to be paid out of said State's appropriation, and the
United States shall in nowise be liable for said one-half.
The Secretary of the Army, in carrying out the provisions of any
Act of Congress, providing for the restraining or impounding of
mining debris in California, may, in his discretion, when in his
judgment the aggregate of appropriations already made by said State
and Congress and available therefor are sufficient to complete the
same, undertake the works necessary thereto by hired labor and by
purchase of supplies and materials therefor, and may accept
payments on account thereof as the work progresses under and
according to the provisions of the acts of the legislature of said
State for such purposes.
