The town grew primarily around the Manhan River, both through its phase as a strictly agricultural community and later, through the Industrial Revolution, when mills and factories were first built in Easthampton, mainly in connection with textile manufacturing and its offshoots. The first of these, the Williston-Knight Button Company, was established in 1847 by Samuel Williston, son of the town's first minister, a Congregationalist named Payson Williston. The company specialized in cloth-covered buttons – a coveted item at the time – and to facilitate the operation of the machinery, a local brook was dammed, creating Nashawannuck Pond. Other mills soon opened nearby, a number of them specializing in elastic and rubber thread manufacturing.
