Here is a colorized post card from the Ada Public Library collection. On the back side it reads: "Oil wells were in the vicinity of County Road 20 and Tonwship Road 25." One was on the Stober farm in the 1920s.

Oil wells were also drilled in Orange Township and other rural sections around Ada and Bluffton. At the height of the oil boom there were 500 oil wells in rural Bluffton and Ada.

When driving on State Route 103 between Bluffton and Arlington, each time you see a brick farmhouse that is a sign that an oil well was drilled on that property.
