128. View from the mountain to the southwest of it down the fish tail double red shale valley, 

 eplit by the great mass of the Pocono rocks, is fine and instructive. 



129. Passing out of the gap Hole Mountain stands on the left (east) a curious synclinal outlier 

 of Oneida capping a ridge of Hudson River, proving that no nonconformobility exists. 



130. A line of great collieries on the mammoth vein extend westward. The gap of the west 

 branch Schuylkill above Minersville, shows a superb arch of the conglomerate. 



131. Making down grade from the conglomerate along the southern and western sides of the 

 red shale valley of the Catawissa Creek crossed by numerous anticlinals from between the Beaver 

 Meadow, Hazleton and Black Creek basins, to the east, and crenulating the (Pocono) Catawissa 

 Mountain to the west. 



132. A curious little oval mountain basin of anthracite lower coal beds (McCauley) stands out 

 on the red shale plain to the right. Notice the rift in its southern side and its fortress like outline.

 the Mountain Creek Valley, with its range of old and extensive limonite mines, open quarries; 

 ore heavily charged with manganese. Ride^to the left (E.) over the divide, on which is Stickler's
