by John Marshall Harlan, United States v. Oregon California Railroad Company…
“ The right it acquired in virtue of the act making the grant, and of the accepted map of its general route, was to earn such of the lands within the exterior lines of that route as were not sold, reserved, or disposed of, or to which no pre-emption or homestead claim had attached at the time of the definite location of its road. That act did not violate any contract between the United States and the railroad company, for the reason that the contract itself recognized the right of Congress, at any time before the line of road was definitely located, to dispose of odd-numbered sections granted. ”
