RIVERS IN NEW-HAMPSHIRE.    595

Salmon Falls or Newiehawannock River, the principal branch
of the Piscataqua, takes its rise in ponds in Wakefield, and forms
the eastern boundary of New-Hampshire, from the north-east corner
of Milton to its confluence with the Piscataqua, at Hilton’s Point.
It borders on the towns of Milton, Farmington, Rochester, Somers-
worth, Rollinsford and Dover. Its waters flow from the whole or
part of twelve towns, in New-Hampshire, and it drains a surface of
over 130,000 acres. Some of the largest manufacturing establish-
ments in the State are located on this river, which has an improved
horse water power of over 4,200.

Soucooh River has its source in three ponds, lying in the south-
erly part of Gilmanton, whence it flows, in a southerly course,
through Loudon, receiving several branches, and forms the bound-
ary line between Concord and Pembroke, falling into the Merri-
mack River below Garvin’s Falls.

Souhegan River has its principal source from a pond in Ashburn-
ham, Massachusetts ; thence it passes through Ashby into New
Ipswich, through the north-west corner of Greenville, in a north-
erly course, thence in an easterly course, through Wilton, Milford,
Amherst, and Merrimack, falling into the Merrimack River.
Babboosuc Brook, flowing from a pond of the same name in Am-
herst, becomes a tributary, in Merrimack. It drains a part or the
whole of eleven towns, comprising an area of about 150,000 acres,
having an improved water power of 2,300. (See Merrimack.)

Spiggot River takes its rise in Hampstead, and the south-east part
of Derry, whence it flows southerly, through Salem and Methuen,
Massachusetts, and joins the Merrimack in the city of Lawrence.

Squamseot River. (See Exeter.)

Suncook River rises in a pond between Gilford and Gilmanton,
near the summit of one of the Suncook Mountains, elevated 900
feet above its base. The water from this pond, passes through two
others at the foot of the mountains, thence it flows a southerly
course, through the north easterly part of Gilmanton, to Barnstead
Center; thence westerly, through Pittsfield, edge of Chichester,
Epsom, and between the towns of Allenstown and Pembroke, and
falls into the Merrimack, near Suncook village. It is about thirty
miles in length, and its waters flow from thirteen towns, and drain
a surface of over 130,000 acres. Its improved water power is about
2,975. Little Suncook has its source in Northwood and Deerfield,
from seven ponds and flows west, through Epsom, into the Suncook.
