212 PHYSICAL GEOGRAPHY. 



New Boston, Lyndeborough mountains, the hilly area of south-west 

 Lyndeborough and Mt. Wilton, and the Rattlesnake hill granitic range of 

 Concord. Perhaps the hilly character of Mt. Vernon, Amherst, Mason, 

 and other localities may be worthy of notice. 



On the east side of the Merrimack are several hilly groups, as Bean 

 hill, Northfield, spreading into Canterbury on the south and into Gilman- 

 ton on the east; the somewhat isolated peaks of Grant, Bradford, and 

 Cogswell hills, in the east part of Gilmanton ; scattered summits in south- 

 west Gilmanton and eastern Loudon, Catamount mountains in Pittsfield, 

 Brush hill, McKoy's Fort, and Nottingham mountains in Epsom, with 

 high land in the west part of Deerfield. Farther south the elevations 

 are of less consequence. There is high land in Allenstown, extending in 

 a range to Hooksett, and terminating in Campbell's hill near the Merri- 

 mack. There are minor ridges following the course of the two bands of 

 quartzite, referred to on p. 50. The Manchester ridge runs a little east 

 of north into the west part of Auburn and Candia, connecting with the 

 abandoned railroad summit at Rowe's Corner, and the Allenstown range 

 beyond. We can also trace an important ridge from Candia through 

 Auburn, Chester, Derry East, and Windham, lying between Corbett's 

 and Policy ponds just before entering Massachusetts. 



The Lowland Country. There are no swamps nor low meadows of any 

 consequence anywhere along the Merrimack river. The clay banks, 

 when present, are usually high up, covered by sand. The high sandy 

 plains commence in New Hampton. Here they are undulating and nar- 

 row. At Bristol they are cut off, and there is no correctness in Dr. 

 Jackson's map, representing the great bend opposite Bristol as composed 

 of drift. They skirt both sides of the river in Sanbornton, Tilton, Hill, 

 and Franklin. In Northfield, Canterbury, Boscawen, and Concord we 

 find the most extensive development of the elevated sandy plains. In 

 the east part of Concord the plain is about one hundred and twenty-five 

 feet above the river, and two miles wide. The plains are contracted to a 

 line at Hooksett, widening in the south part of the town. The Piscata- 

 quog river develops this sandy plain several miles back into Bedford and 

 Goffstown, from Manchester. Litchfield is chiefly a sandy plain. Merri- 

 mack, Amherst, Nashua, and Hudson possess large areas of the same, 

 but the land so far down the river is everywhere low, and is mostly
