ished for its sawmills,
gristmills, and mechanics' shops of various kinds. Billerica, Dracut,
and Tewksbury gave like encouragement. About the time of the Revolution
a sawmill was built below Pawtucket Falls and owned by Judge John Tyng.

Toward the close of the last century the lumbering industry on the
Merrimack grew into prominence; and, in 1792, Dudley A. Tyng, William
Coombs, and others, of Newburyport, were incorporated as "The
Proprietors of the Locks and Canals on Merrimack River." This canal,
which was demanded for the safe conduct of rafts by the Falls, was
completed in 1797, at an expense of fifty thousand dollars. The fall of
thirty-two feet was passed by four sets of locks.
The first bridge across the Merrimack was built, in 1792, by Parker
Varnum and associates; the Concord had been bridged some twenty years
earlier.

In 1793, the proprietors of the Middlesex Canal were incorporated.
Loammi Baldwin, of Woburn, superintended the construction. The canal
began at the Merrimack, about a mile above Pawtucket Falls, extended
south by east thirty-one miles, and terminated at Charlestown. It was
twenty-four feet wide and four feet deep and was fed by the Concord
River. It cost $700,000, and was completed in 1804,--the first canal
in the United States opened for the transportation of passengers and
merchandise. For forty years it was the outlet of the whole Merrimack
valley north of Pawtucket Falls.
The first boat voyage from Boston, by the Middlesex Canal and the
Merrimack River, to Concord, New Hampshire, was made in 1814; the first
steamboat from Boston reached Concord in 1819.
The competition of the Middlesex Canal ruined the Pawtucket Canal, as it
in turn, in after years, was ruined by the Boston and Lowell Railroad.
Navigation finally ceased on its waters in 1853, since which date its
channel has been filling up and its banks have been falling away.
In 1801, Moses Hale, whose father had long before started a fulling-mill
in Dracut, established a carding-mill on River Meadow Brook,--the first
enterprise of the kind in Middlesex County.
In 1805, the bridge across the Merrimack was demolished and a new bridge
with stone piers and abutments was constructed. It was a toll-bridge as
late as 1860.
The second war with England stimulated manufacturing enterprises
throughout the United States; and sev
