Tlie Lower Mahoning Sandstone is not pebbly at this locality, and is 

 rather inclined to-be flaggy, though some portions of it are quite massive. 



Tlie Upper Freeport coal lies about 10' below the level of Cheat river at 

 the mouth of Bayles' run, where our section ends. On the east baijk of 

 the stream, it rises above drainage and was once mined as fuel for the 

 Laurel Iron Works, situated one-half mile below. The coal is reported 

 four feet thick and of good quality. 



In passing up the river south-eastward from the ferry, the rocks rise 

 very rapidly toward the Chestnut Ridge axis, and the top of No. XII makes 

 its appearance above river level in a massive dam-like wall, just below 

 Mr. Ley's, and not quite a mile above the ferry. 



The intervening Lower Coal Measures are not well exposed, being con- 

 cealed by the immense heaps of talus under the clifls of Mahoning sand- 

 stone, but a vertical measurement from the outcrop of the Upper Fi'eeport 

 coal where seen along the Bruceton turnpike opposite Mr. Ley's, down to 

 the top of the No. XII Conglomerate makes their thickness 250'. The 

 only coals in these measures here are the Upper Freeport, and one that 

 comes about 160' below it, being \^'-2' thick, and very excellent coal. It 

 is either the Middle or Lower Kittanning, most probably the latter. 



Continuing on up the river above Mr. Ley's, the rocks rise about 400'- 

 450' to the mile, and bring the top of the Mauch Chunk shales (No. XI) 

 above river level at the mouth of Quarrj^ run, a small stream that empties 

 into the east bank of Cheat, one mile and a half above Ice's Ferry. It 

 cuts a fine exposure through No. XII and in descending to the river along 

 its right bank this section was got. Sec. 3 :
