MIDDLETOWN. G 5 . 121 



The rocks of the township belong to the Cat skill series, 

 with the exception of a narrow trench in the top of the C i Ile- 

 um i ig along the lower portion of Wyalusing, and also along 

 the North Branch of the same ; but while the top of the 

 Chemung is thus above drainage along the valley of the 

 Wyalusing and its branches, there is no locality in the town- 

 ship where any of the rocks of the series are exposed, be- 

 cause Drift covers everything along the channels of the 

 streams, and often far up the sides of the hills. 



The massive lower member of the New Milford group is 

 often seen skirting the tops of the hills on either bank of 

 the Wyalusing in bold cliff outcrops 200' to 250' above the 

 level of the stream. 



Just above Grangerville this New Milford Lower sand- 

 stone is seen on the north bank of the stream at an elevation 

 of 1100' A. T. and quite massive. 



At the cross roads, about one mile below Grangerville, the 

 same New Milford Lower sandstone is seen and there we 

 get the following : (Fig. 33.) 



Grangerville section. 



1. Sandstone, massive, gray, 25' 



2. Concealed, 75 



3. New M ilford lower sandstone, (base 1135' A. T.), .... 20' 



4. Concealed, 80' 



5. Red shale, seen, 25' 



6. Concealed to level of the Wyalusing, . . .... 80' 



No. 1 is the massive cliff-rock which so often comes 80' to 

 100' above the base of the New Milford Lower sandstone ; 

 it is here quite massive, current-bedded, and crops out in a 

 bold cliff along the hills. 



About two miles directly north from this last locality, 

 near Tupper's school-house, the New Milford Lower sand- 

 stone is seen at an elevation of 1150' A. T. at base ; it juts 

 of the hill out in a very massive ledge, and is also current- 

 bedded. 



Near the western line of this township, at the mouth of 

 the North Branch of the Wyalusing, the New Milford- Lower 

 sandstone comes in the hills 270' above the level of the stream 

 or 1140' A. T. Therefore if the Drift did not conceal every-
