New London county. This town was taken from Preston in 1815, and is separated from Lisbon by Quennebaugh river. The Pochaug, a sluggish stream, passes through the town. The principal village, which is very neat and pretty, containing about 900 inhabitants, is called Jewett City. The city lies on the east side of the Quennebaug, at this place a very powerful stream, and contains three extensive cotton factories, a church, bank, and a number of handsome buildings.—This little city is said to be very prosperous in its manufacturing and commercial concerns. It lies 8 miles N.E. from Norwich and 46 E.S.E. from Hartford. There are other manufactories of cotton in this town, and some of wool. The surface of Griswold is hilly; its soil a gravelly loam: some produce is sent to market, and about 3,000 sheep are kept. Population, 1830, 2,212.
