PHYSICAL GEOGRAPHY. 



Harrisville, thence into Marlow, around most of Alstead, and up the 

 valley of Cold river into Lempster. The line returns so as to pass south 

 of Acworth village, thence northerly, and north-easterly irregularly, nearly 

 to Sunapee lake. The line now runs back among the hills on the north 

 branches of Sugar river, even into Springfield, but meanders back to 

 Claremont, and then passes northerly on the flanks of Croydon and 

 Grantham mountains to East Lebanon, thence southerly to the Orange 

 railroad summit, thence to the north line of Canaan, and westerly nearly 

 to the gap between Moose and Smart's mountains, thence southerly to 

 the south end of Moose mountain, and thence northerly to the Swift 

 Water valley in Haverhill. Thence the line passes south-easterly towards 

 the Woodstock notch, and thence irregularly to Franconia iron works, to 

 North Lisbon, and up the Ammonoosuc river nearly to the Wing Road 

 station. The Whitefield summit (Boston, Concord & Montreal Railroad) 

 lies above one thousand feet ; and, therefore, this contour returns to Little- 

 ton, passes around Palmer hill, and thence into Whitefield through Dalton. 

 From the very bank of the Connecticut in South Lancaster the line runs 

 into Lancaster, Northumberland, around Mt. Lyon, and up the Grand 

 Trunk Railway into Stark and Milan. Returning, the line extends up the 

 Connecticut to Columbia, and up Nulhegan river in Vermont two or three 

 miles. Gardner's Mountain range in Lyman is the principal island west 

 of this looo-feet level on the Connecticut slope. 



The \i,oo-feet line. In the south part of the state this line appears 

 chiefly along the Merrimack-Connecticut water-shed, as a series of 

 islands. First there are the Barrett, Pack Monadnock, and Monadnock 

 series. Next, the heights in Nelson, Stoddard, Springfield, and the 

 Sunapee range. On the east Mt. Kearsarge, and on the west Croydon, 

 Grantham, Moose, Smart, Cuba, and Piermont mountains, reach above 

 this line. Other areas are connected with the Cardigan range, Groton 

 and Plymouth heights, Gunstock, Ossipee, and Green mountains. 

 Another prominent expanse above 1500 feet lies east of Baker's river, 

 in Wentworth, Warren, and Rumney. 



The entire White Mountain area is encircled by this contour line, with 

 very narrow strips of a lower level, marking off Pequawket and the Starr 

 King group. There are two areas to the north above this line, one east 

 of the Androscoggin valley, and the other north of the Grand Trunk
