All moneys received from royalties and rentals under the provisions of this chapter shall be deposited in the Treasury of the United States, and disposed of in the same manner as rentals and royalties under the provisions of section 191 of this title.

The Secretary of the Interior is hereby authorized to perform any and all acts and to make such rules and regulations as may be necessary and proper for the purpose of carrying this chapter into full force and effect.
