Clark Paper Mill site is purchased.

George Clark purchases 14 acres of land from the Town of Dorchester at today’s 864 River Street. After he subsequently builds a factory there, it becomes the longest paper manufacturing site in continued operation in the U.S. The mill is taken over by William Sumner in 1796 (1786), by Tileston & Hollingsworth in 1836, operated by James River Company from 1983 to 1987, by the Hyde Park Paper Company beginning in 1989, by Bay State Paper Company in 1995. It closes in 2004, and the site is subsequently developed as a shopping center.
