Forest Paper Co. smokestacks, Yarmouth, ca. 1900
Workers on rotating shifts produced soda pulp for making paper 24 hours a day. The process included slicing poplar logs into small chips that were put into large digesters that pressure cooked them. Soda or lye was added at high heat to reduce the chips to pulp. The pulp was then strained or dried and sent off to papermakers all over the world.
