A cheese factory was built in Pittston in the late-1800s. By 1885, an addition was added to the cheese factory which housed a grain crusher and planing machine, diversifying operations. The cheese factory burned down twice, once in the late-1800s and once in 1900, and was rebuilt after both fires. By 1900, the factory had reached its peak, producing 20 cheeses a day. The cheese was transported to Spencerville where it was then shipped to Montreal to be exported internationally. The factory closed in the 1940s.
