William O. Douglas,
United States v. Union Pacific Railroad Company…
“ We would have to forget history and read legislation with a jaundiced eye to hold that when Congress granted only a right of way and reserved all 'mineral lands' it nonetheless endowed the railroad with the untold riches underlying the right of way. Such a construction would run counter to the established rule that land grants are construed favorably to the Government, that nothing passes except what is conveyed in clear language, and that if there are doubts they are resolved for the Government, not against it. ”
