The Secretary of Agriculture is authorized, where the public interest justifies, to cooperate with or assist public and private agencies, organizations, institutions, and persons in performing work on land in State, county, municipal, or private ownership, situated within or near a national forest, for which the administering agency, owner, or other interested party deposits in one or more payments a sufficient sum to cover the total estimated cost of the work to be done for the benefit of the depositor, for administration, protection, improvement, reforestation, and such other kinds of work as the Forest Service is authorized to do on lands of the United States:
Cooperation and assistance on the same basis as that authorized in subsection (a) of this section is authorized also in the performance of any such kinds of work in connection with the occupancy or use of the national forests or other lands administered by the Forest Service.
Moneys deposited under this section shall be covered into the Treasury and shall constitute a special fund, which is made available until expended for payment of the cost of work performed by the Forest Service and for refunds to depositors of amounts deposited by them in excess of their share of said cost:
