 Atlantic coast, Hudson valley, Mohawk valley, Champlain valley, 

 St. Lawrence valley, Great Lakes and Central Lakes. 



The Western plateau includes the western portion of the central 

 plateau extending across the southern part of the State from the 

 Hudson valley to Lake Erie. This plateau extends from Lake 

 Erie to the valley of Seneca lake and to the point due south of 

 Seneca lake where the two main branches of the Susquehanna 

 river unite. 



The Eastern plateau includes the portion of the central plateau 

 to east of the valley of Seneca lake and the point due south of 

 Seneca lake where the two main branches of Susquehanna river 

 unite. It is terminated to the east by the Hudson river valley. 



The Northern plateau mcludes the region north of the Mohawk 

 valley, west of the Champlain valley and east and south of Lake 

 Ontario and the St Lawrence valley. 



The Atlantic coast region includes Long Island, New York city 

 and its neighborhood, to the northern part of Westchester county. 

 With the flat, sandy beaches and low ground surrounded by water, 

 with hills never rising more than one hundred feet, this region is 

 entirely open to the influence of sea winds. It has the highest 

 temperature and precipitation in the State. 



The Hudson valley is a narrow strip of land on both sides of 

 the river, surrounded by hills and tablelands as far as the High- 

 lands. Higher up, the valley widens into the extensive plains on 

 the west side of the river. Although this region is nearly at sea 

 level, its climate is generally much severer than the Atlantic 

 coast region, owing to the cold northern winds flowing from 

 Canada along the valley of Lake Champlain. 



The Mohawk valley extends along the Mohawk river to beyond 

 Borne. The rainfall is about two inches less than that of the 

 northern plateau. 



The Champlain valley includes the valleys "of Lakes Champlain 

 and George, only a few hundred feet above sea level for the whole 

 distance. On the east, in Vermont and Massachusetts, moun-
