SDCL § 49-16A-59: Filing as vesting right to use--Duration of right--Forfeiture for failure to use.

The filing with the commissioner of school and public lands of the map required by § 49-16A-58 authorizes the railroad, for one year from the filing date, to enter upon the land so surveyed and selected and construct a road thereon. If the railroad does not construct its road across the land within one year after the filing of the map, it forfeits all rights acquired by the filing of the map.
