PHYSICAL GEOGRAPHY. 



from the east line of the Merrimack basin in Wolfeborough, and passes 

 east through the north corner of Brookfield and near the centre of Wake- 

 field to the Maine line, which it crosses between Balch and East ponds. 



Nearly the whole of Carroll county is comprised within the Saco basin, 

 which has in New Hampshire an average width of about eighteen miles, 

 and a length, measured on our eastern boundary, of forty-six miles. 



Piscataqua River. The south-east boundary of this district starts from 

 the Merrimack river water-shed at East Kingston, and passes east through 

 Kensington village, thence north-east through the east corner of Exeter, 

 thence east and north-east through North Hampton to Breakfast hill 

 between Greenland and Rye, from which it passes north-east through 

 Rye to Odiorne's point at the south side of the mouth of the Piscataqua. 



This basin includes in New Hampshire nearly all of Strafford and half 

 of Rockingham counties, averaging about eighteen miles in width, and 

 forty-five miles in length, measured from Wakefield to East Kingston. 

 From the sources of the Pawtuccaway river to the mouth of the Piscat- 

 aqua is thirty miles, from which point the width of this district diminishes 

 northward, being ten miles at Farmington. 



Hamptojt Falls River, &c. The portion of New Hampshire south of 

 the last described water-shed and east from East Kingston and South 

 Hampton, forming our sea-coast slope, is drained directly into the ocean 

 by Hampton Falls and Taylor's rivers and numerous smaller streams, not 

 being included in either of the principal hydrographic districts adjacent. 



The most distant point of this area from the ocean is in the south-east 

 corner of Exeter, six miles from the coast. Its length from Odiorne's 

 point to the Massachusetts line is thirteen miles. 



The accompanying map shows the dimensions and relative areas of 

 these hydrographic basins, and the course of water-shed lines. 



Connecticut River System. 



The basin of the Connecticut comprises about 3,060 square miles in 

 New Hampshire, or three tenths of the area of the state. The line of 

 low water on the west side of this river forms the boundary between this 

 state and Vermont ; and Hall's stream, the third considerable tributary 

 from the right below its source, continues this boundary between our 

 state and the province of Quebec. In addition to this area drained from
