RIVER SYSTEMS OF NEW HAMPSHIRE. 3<DI 



across Strafford. Thence it extends south through Northwood to Saddle- 

 back mountain, thence a little south of west through Deerfield to Aliens- 

 town line, near Shingle ponds. Thence it passes on a curve through the 

 west and south portions of Candia to Patten's hill. From this point it 

 follows nearly the west and south boundary lines of Chester, next passing 

 through the north part of Hampstead, between Island porid and Phillips 

 pond, Sandown, thence north-east to near the Town hall in Danville, 

 thence east through Kingston village, the large ponds of Kingston 

 being tributary to Powwow river on the south. Thence its course is 

 south-east, passing through East Kingston village, and the south-west 

 corner of Kensington; to the Massachusetts line, near the boundary 

 between South Hampton and Seabrook. 



The width of the Merrimack basin at its source, measured from Mt. 

 Willey to Cannon or Profile mountain, is about fifteen miles. This 

 increases to the section from Brookfield across Winnipiseogee lake to 

 Orange, which is forty-three miles. Thence southward to Manchester it 

 remains very nearly the same. From near Manchester this area widens 

 on the east, bending in the direction of the river's mouth at Newbury- 

 port. Its greatest width in New Hampshire, from the west line of Sea- 

 brook to Monadnock mountain, is sixty miles. Its length, from Profile 

 lake south to the Massachusetts line, is ninety-eight miles. 



Androscoggin River. The water-shed between the Androscoggin and 

 Saco extends from the summit of Mt. Washington to Pinkham notch, 

 passing between Huntington's and Tuckerman's ravines, and thence 

 nearly east, through Bean's purchase to the Maine line. Its course is 

 across high mountain ranges, which extend north and south, and are 

 covered with unbroken forest. 



By reference to our hydrographic map, it will be seen that Coos county, 

 north from Mt. Washington, is nearly equally divided between the Con- 

 necticut and Androscoggin basins. The latter, as far as included in New 

 Hampshire, averages about eleven miles in width, being sixteen miles 

 wide at its southern end, and fifteen at the sources of the Swift Diamond 

 river, while it is narrowed to almost nothing at Mt. Carmel. The length 

 of this hydrographic district, measured on the eastern boundary of the 

 state, is seventy-one miles. 



Saco River. The water-shed between the Saco and Piscataqua starts
