with him in business. In 1821, the firm opened Whipple's Canal. The
business was enlarged from time to time and was at its zenith during the
Mexican War, when, in one year, nearly five hundred tons of powder were
made. The manufacture of powder in Lowell ceased in 1855. In 1818, also,
came Thomas Hurd, who purchased the cotton-mill started by Whiting and
Fletcher and converted it into a woolen-mill. He soon enlarged his
operations, building a large brick mill near the other. He was the
pioneer manufacturer of satinets in this country. His mill was destroyed
by fire and rebuilt in 1826. About this time he built the Middlesex
(Mills) Canal, which conveyed water from the Pawtucket Canal to his
satinet-mills, thus affording additional power. His business was ruined
in 1828 by the reaction in trade; and two years later the property
passed into the hands of the Middlesex Company.

The year 1818 also brought Winthrop Howe to town. He started a mill for
the manufacture of flannels at Wamesit Falls, in Belvidere, and
continued in the business until 1827, when he sold out to Harrison G.
Howe, who introduced power-looms, and who, in turn, sold the property to
John Nesmith and others in 1831. In the year 1819 a new bridge across
the Concord River was built to replace the old one built in 1774. About
this time the dam across the Concord at Massic Falls was constructed,
and the forging-mill of Fisher and Ames was built. The works were
extended in 1823, and continued by them until 1836, when the privilege
was sold to Perez O. Richmond.
