Saccarappa Falls and Congin Falls provided water power for early mills within the city. In 1829, a sawmill was built at the former which made the mill town noted for its lumber. Other industries followed, manufacturing grain bags, machinery and water wheels, carriage and harness, boots, shoes and moccasins, tinware, leather board, bricks, wooden boxes, box shook, meal and flour. The Portland Manufacturing Company built a cotton textile mill at Saccarappa Falls for making "sheetings, stripes and ducks." A paper mill was built at Cumberland Mills, once an Indian planting ground known as Ammoncongin. By 1859, it produced 1,000 tons of paper annually. In 1867, the factory's name would change to the S. D. Warren Paper Mill.
