terraces and deltas was less. The name of the lake is derived from 

 the town of Newman, the terminus of the railroad, where well- 

 preserved levels occur on the north and south. The drainage of 

 Lower Newman is assumed to be westward, perhaps following the 

 course now taken by the Chateaugay branch of the Delaware and 

 Hudson Railroad for some distance. 



On the map there is more area exhibiting the Lower Newman than 

 there is showing the upper. West of Paul Smith's station, about 

 Harrietstown, west of Bloomingdale, south of Lake Clear Junction, 

 and a mile southwest of Barnum pond are typical occurrences. 



The three glacial lakes above described all had, apparently, west- 

 ward drainage, but in the succeeding lake (or group of lakes) we 

 find a body of water whose outlets were to the east. 



Saranac Glacial Waters 



The series of sand plains, terraces etc., that come under this head 1 

 have such a wide range (1450 to 1660 feet) that they must have been 

 produced by a series of glacial lakes, or by deposition by aggrading 

 streams which no longer exist, or by a combination of both. Doctor 

 Cushing is of the opinion that ' ' these sands were probably deposited 

 as deltas in a large and irregular, shallow lake formed back of the 

 ice tongue which occupied the ' lake belt ' during its slow retreat 

 north, the material being furnished by the subglacial and englacial 

 streams flowing into the lake at the ice margin." 



As nearly two-thirds of the Saranac sheet exhibits terraces and 

 sand plains of this level, it was proposed that the name " Saranac 

 glacial waters " be applied to these levels. Perhaps this is not a 

 very happy choice in the present case in view of the large number of 

 names involving " Saranac," but it is thought best to retain it in 

 consideration of the general history of the glacial lakes of the Adiron- 

 dacks as a whole. 



Not all the areas indicated upon the glacial map were covered by 

 the waters of this series of lakes. Some portions represent outwash 

 plains from the glacier, deposited by the overburdened aggrading 

 streams from the melting ice, forming deltas in standing waters, the 

 surface of which, in many places, was above the water level. Such 

 a case is shown in the northern portion of the great sand plain that 

 stretches from Lake Clear Junction north to Paul Smith's station. 

 The district about the junction was probably under water, but the
