In all cases when county agricultural societies neglect for two years to hold a county fair or cease to exist, in any county where payments have been made for real estate or improvements upon such real estate for the use of a county agricultural society, then all such real estate and improvements shall vest in fee simple in the county, and the district court of the county, upon proof thereof, shall, upon petition of the county board, make a proper decree vesting the title of such property in the county.
