ries comes into the section and skirts the hills with a very 

 bold outcrop on the south side of the river, and is often 

 seen jutting out far up the slopes in a line of massive cliffs. 

 In the steep bluff, about one mile and a half below Sus- 

 quehanna Depot, the following section was obtained in de- 

 scending the hill on the left bank of the river : (Fig. 18.) 



Susquehanna Depot lower section. 



1. Massive sandstone, 12' 



2. Shales, grayish, sandy, 30' 



3. Massive sandstone, 35' 



4. Concealed, 70' 



5. Massive sandstone, (New Mil ford Lower,) 1250' A. T.,) . 10' 



6. Concealed to level of the river, 380' 



Nos. 1 to 5 represent the lower half of the New Milford 

 sandstone group, and the base of No. 5 has an elevation of 

 1250' above tide. 



All of these sandstones are of a greenish-gray color, and 

 much current bedded ; large blocks of the same lie strewn 

 over the hillside almost from top to bottom. 



A very red shale, 10' thick is seen along the road a short 

 distance below Susquehanna Depot and 275' below the base 

 of the New Milford Loioer sandstone. This is about 75' 

 below the top of the Chemung, and very possibly represents 

 the Mansfield iron ore horizon ; since a short distance above 

 Susquehanna, and along the Erie E.R. many nodules of iron 

 ore are seen which have come down from the bluff above 

 out of this same horizon. 



About one fourth mile above Susquehanna Depot, the 

 following section is seen in a cutting along the Erie RR. : 

 (Fig. 19.) 



Susquehanna Depot upper section. 



1. Somewhat massive sandstone, 10' 



2. Shales, 4' 



3. Sandy shales, olive, 8' 



4. Reddish shales with iron ore, 10' 



5. Flaggy sandstones to track, fossiliferous, 10' 



This series is in the top of the Chemung and in No. 5 are 

 seen many specimens of JRhychonella contracta. The bot- 

 tom of this stratum comes at 940' A. T. and it is probably
