 Not content with the sawmill, Mills devised a way for the same wheels to power the North Star Mill, a gristmill that Oren Hutchinson had built at the town of Thorp in 1883, to provide feed for livestock and flour for the local residents.The mill was best known for its leading brand "Tip Top".The Pleasant Grove post office was moved in 1880 to a site near the mills and changed its name to Milton post office to reflect the name of the small settlement that had sprung up at that location, which was named for Milton Young.
