Pittston, 44 573' 



Level of Susquehanna river, (Pittston,) 44 535' 



Rate of fall: 1488' in 44 miles ; or 33'. 9 per mile*. 



The profile across the center of the east and west divide 

 is given by the levels on the Del. Lack. & West. R. R. as 

 follows : 



Delaware, Lackawanna and Western railroad levels. 



Miles. A. T. 



Binghampton in New York, 843' 



Conklin in New York, 8> 849'

New York and Pennsylvania State line, .... 12 860' 



Great Bend, 14 876' 



At this point the R. R. leaves the Susquehanna valley and 

 turns south up Salt Lick creek, the rise of whose valley is 

 shown by the following : 



New Milford, 2(H 1084' 



Summit cut at bead of Salt L. creek, 22(Bar.)1150 



The R. R. here passes through a great gap in the divide, 

 the summits of the hills on either side rising 500' higher 

 than the railroad bed. From this summit (1150') the R. 

 R. descends the valley of Martins creek with the following 

 slopes : 



Montrose Depot, 27| 1050 



Oakley's, 32£ 942' 



Foster, 34£ 890' 



Nicholson, 40| 766 



Level of Tunkhannock, mouth Martin's creek, . — 700' 



At this point the line of the D. L. & W. R. R. leaves the 

 water-way, and ascending the divide between Tunkhannock 

 waters and the Lackawanna, passes across the Lackawan- 

 nock mountains through a gap into the Lackawanna coal 

 basin, thus : 



Tunnel, 44| 963' 



Factoryville, 46| 917' 



Abington, 51? 1055' 



Clark's Summit, 54? 1239'
