Rufus Wheeler Peckham, Peabody v. United States (175 U.S. 546…
“ That act stated that those who are placed in possession are not 'authorized to exchange, sell, or alienate the same until they shall have acquired title,' etc. A grant, therefore, would not be presumed even upon proof of exclusive and uninterrupted possession, so long as it was entirely consistent with the evidence produced in the case, which shows that it originated in a mere license, and there is no proof from which it can be claimed that its character changed from that of a licensee to that of one in possession adversely and under a claim of title by a grant from the government. ”
