The people of the State, through their legislative authority, accept the provisions and benefits of the act of Congress known as the "Migratory Bird Conservation Act," approved February 18, 1929. Upon approval by the commission, they consent to the acquisition by the United States, by purchase, lease, gift, or devise, of such areas of land, water, or land and water, within the State, as the United States or its properly constituted officers or agents may deem necessary for migratory bird reservations in carrying out the provisions of such act of Congress; saving and reserving, however, to the State such full and complete jurisdiction and authority over all such areas as are not incompatible with the administration, maintenance, protection, and control thereof by the United States under the terms of such act of Congress, and saving and reserving to all persons within such areas all rights, privileges, and immunities under the laws of the State, insofar as they are compatible with the administration, maintenance, protection, and control of such areas by the United States under the terms of such act of Congress.
