If, in the adjustment of said grants, it shall appear that the homestead or preemption entry of any bona fide settler has been erroneously canceled on account of any railroad grant or the withdrawal of public lands from market, such settler upon application shall be reinstated in all his rights and allowed to perfect his entry by complying with the public-land laws: Provided, That he has not located another claim or made an entry in lieu of the one so erroneously canceled: And provided also, That he did not voluntarily abandon said original entry: And provided further, That if any of said settlers do not renew their application to be reinstated within a reasonable time, to be fixed by the Secretary of the Interior, then all such unclaimed lands shall be disposed of under the public-land laws, with priority of right given to bona fide purchasers of said unclaimed lands, if any, and if there be no such purchasers, then to bona fide settlers residing thereon.
