English: Map B is substituted therefor as the official segregation sheet by which the government determine, what land is patented, what land is subject to patent and what land belongs to each respective patent; it is constructed on theoretical lines entirely, based upon original records. Map A is practice, map B is theory; map A is discarded by the land department, map B is adopted. Claims are thereby shifted about and officially anchored out of position. Land which is patented is thrown open to acquire- ment and may be patented to outsiders. Ground which is actually unpatented and open is construed to be patented to claims which occupy entirely different tracts....and as to every land section in all the mineral districts of Colorado and every other mining state.
