FREDONIA, Kan.  -  One of the biggest grass fires to hit Kansas in the current spell of dry, windy weather has burned more than three square miles in the southeast.  Wilson County Emergency Manager Terry Lyons says the agency was alerted around 2:30 p.m. Thursday to hay bales and a field on fire south of Fredonia. Firefighters from several departments responded.
     The flames spread north over more than 1,900 acres before the fire was mostly contained around 6:30 p.m. Some areas were expected to burn at least into Friday.  Firefighters were able to protect houses, but several outbuildings were destroyed and pipelines from the many oil and gas wells in the area were damaged. Authorities said at least two firefighters were treated for smoke inhalation.
     The cause of the fire wasn't immediately known.
