Taking four years to build, Jacob Tapola Davidson, a Finnish immigrant, finished the wind-power gristmill in 1904, the octagonal shape inspired by his coffee pot. The grinding stones, which came from rock near Amnicon Falls, could grind 300 pounds of grain an hour. By using long poles attached to the green section, the grinding speed was controlled by rotating the mill’s upper section with its 17 foot long sails.
