If the title examination shall disclose incumbrances upon the land, or other objections, which, in the judgment of the Department of Forests and Waters¹ or the Board of Game Commissioners, whichever is contemplating the purchase of the land, will render the title unmarketable or undesirable for the State to own, the county commissioners shall then proceed to remove such objections to title, and cure such defects, so far as it may be possible to do so, or may be required by the practice of the Department of Forests and Waters or the Board of Game Commissioners in the purchase of lands. The purchase of said land shall not be further proceeded with until the title shall be rendered acceptable to the department or commission contemplating purchase. In case the county commissioners neglect or refuse to remove objections to title when required by the department or the commission, whichever is contemplating the purchase of the land, such agency may, after a reasonable time, not exceeding six months, notify the commissioners that it refuses to consider the further purchase of the land so offered. The time for removal of objections may be extended by the department or commission for cause shown.
