The preceding statements of area above certain elevations are 

 rather general — time has not been taken for detailed estimates. 

 There are, however, from 8000 to 10,000 square miles available. 

 From all these centers, uncontaminated streams of great natural 

 purity issue. There are also several minor points throughout the 

 State for which the same statement is true. 



The Adirondack water center is separated from the Catskill by 

 the valley of the Mohawk river, which receives drainage from 

 both — the East and West Canada creeks and other tributaries of 

 the Mohawk on the north side of the valley rising in the Adiron- 

 dack center, while the Schoharie creek on the south side is an 

 important tributary from the Catskill center. 



In addition to the Mohawk river, other important streams of 

 the State issuing from the Adirondack center are the Black, Oswe- 

 gatchie, Grasse, Raquette, St Regis, Chateaugay, Great Chazy, 

 Saranac, Ausable, Bouquet and Hudson rivers. 



From Catskill center, in addition to Schoharie creek, we find 

 issuing the headwaters of the Susquehanna, Delaware and Wall- 

 kill rivers and Esopus creek. 



The Allegheny center supplies the headwaters of Cattaraugus 

 creek, Genesee, Chemung, Canisteo, Tioga, west branch of the Sus- 

 quehanna and Allegheny rivers. 



From Rensselaer center issue Hoosic river, Kinderhook creek, 

 Claverack creek, the Jansen kill and Croton river. 



From Chenango center issue the Chenango and Tioughnioga 

 rivers and Oriskany, Oneida and other small creeks, flowing north. 



From Lowville center Salmon river issues, together with Sandy 

 creek, Fish creek and other small streams. 



Generally speaking the main river valleys of New York are at 

 comparatively low elevations, as may be sufficiently appreciated 

 by considering the elevation of a few of the principal streams. 

 The main Black river valley is less than 800 feet above tide water; 

 Oswego river, with its principal tributaries, the Oneida and 

 Seneca, is less than 500 feet ; main Mohawk river is less than 500 

 feet; Genesee river, between Rochester, Mount Morris and Dans- 

 villo, is about 500 to 600 feet; main Hudson river, below Glena 

 Falls, is less than 200 feet; main Susquehanna river is less than 

 1.000 feet, as is also lli< k main Delaware; main Allegheny river in 

 the State of New York is about 1,000 feet; Lake Erie is 573 feet;
