Upon payment of the purchase price, the Secretary of the Interior is authorized by appropriate deed to convey all the right, title, and interest of the United States of, in, and to said lands to the purchaser at said sale, subject, however, to such reservations, limitations, or conditions as said Secretary may deem proper: Provided, That not over one hundred and sixty acres shall be sold to any one person.
