Now, therefore, by virtue of the authority so vested in me, and after investigation as provided in said Act as amended having found and hereby declaring that the abolition of the Board of Indian Commissioners created by Section 2039, Revised Statutes (U.S.C., Title 25, Sec. 21), is necessary to accomplish the purposes above set forth, I hereby abolish the said Board and order that its affairs be wound up by the Secretary of the Interior and its records, property, and personnel be transferred and/or remain under the supervision of the Secretary of the Interior.
This order shall take effect upon the sixty-first calendar day after its transmission to Congress unless otherwise determined in accordance with the provisions of Section 407 of the Act cited above, as amended as aforesaid.
