If it shall appear, upon the completion of such adjustments,
respectively, or sooner, that lands were, from any cause, prior to
March 3, 1887, erroneously certified or patented, by the United
States, to or for the use or benefit of any company claiming by,
through, or under grant from the United States, to aid in the
construction of a railroad, it shall be the duty of the Secretary
of the Interior to thereupon demand from such company a
relinquishment or reconveyance to the United States of all such
lands, whether within granted or indemnity limits; and if such
company shall neglect or fail to so reconvey such lands to the
United States within ninety days after the aforesaid demand shall
have been made, it shall thereupon be the duty of the Attorney
General to commence and prosecute in the proper courts the
necessary proceedings to cancel all patents, certification, or
other evidence of title prior to March 3, 1887, issued for such
lands, and to restore the title thereof to the United States.
