"Quascancunquen" means "waterfall," referring to the falls in Byfield where Central Street crosses the Parker River. In 1636, the first water-powered mill was established at the falls. Gristmills and sawmills were built, and in 1794, the first textile mill in Massachusetts. At Byfield in 1763 was founded the nation's first boarding preparatory school, Dum'r (Dummer) Charity School, known subsequently as Dummer Academy, Governor Dummer Academy, and now The Governor's Academy. It was also site of the first female seminary, founded in 1807. Byfield developed into a mill village, and once had six water-powered mills, manufacturing various products from woolens to snuff.
