The Millers River serves as a town line between Erving and Wendell, both in Massachusetts.  Manufacturers in Erving produced mostly lumber, with a business that made children’s carriages and another that made parts for pianos, organs, and melodeons. Prominent on this map is the “Erving Castle or Hermit’s Cave” where a cliff formed a natural cave that was inhabited in the late 1860s by John Smith, a Scotsman, who became something of a celebrity for his rugged lifestyle. He lived there for more than twenty years before being taken into a Montague home, where he died in 1900. Wendell was more rural, with just 10 businesses listed.
