center of the coal basin, and there the dip begins to flatten 

 very fast, so that when we come to the Elk mountains at the 

 northern line of the township and only five miles away, the 

 strata have become almost horizontal. 



The Sonth knob of the foregoing range, is just at the north- 

 ern edge of Clifford, and descending its summit the follow- 

 ing section was made : (Fig. 43.)

Nos. 2 and 4 make cliffs around the knob ; some pebbles 

 occur in the latter ; both exhibit much false bedding. 



The Mt* Pleasant conglomerate runs out in a broad bare 

 projecting cliff at the southern point of the mountain and 

 forms a great bold ledge along its entire south-western face. 

 It is from its upper surface that the remarkably line view 

 of the country to the southward is obtained, and from which 

 it has received the name of "Prospect Hock." 



Near its base we find a layer 2' to 3' thick filled with quartz 

 pebbles, many of which are one inch in diameter. The most 

 of them are reddish or rose colored and very irregular in 

 outline. 



Not all of the Mt. Pleasant red shale was exposed, but 

 enough was seen at several horizons in it to show that the 

 whole interval is of the same material ; it is of a dark-red 

 color and looks very much like the same stratum at Mt. 

 Pleasant in Wayne county.
