White.] 480 . [Oct. 20, 



At this ferry, the road leading from Morgantown, W. Va., to Union- 

 town, Pa., crosses the river which, emerging from the canon of No. XII, 

 one mile above, now flows between low hills of the Barren measures witli 

 the Mahoning sandstone making bold cliffs along the immediate banks 



About one-fourth mile above the ferry, a small stream puts into the west 

 bank of Cheat over the Mahoning sandstone cliffs, and descending it from 

 the jMorgantown road near Mr. Bayles, the following succession may bo 

 seen, Sec. 1 : 



1. Coal (crinoidal) 1' 



2. Shales, gray 10' 



3. Shales, red 25' 



4. Shales and concealed 45' 



5. Shales, brown, sandy 10' 



6. Coal, Bakerstown , 2'^ 



7. Sandy shales and shaly sandstone 50' 



8. Upper Mahoning sandstone, very massive and pebbly. 30' 



9. Shaly sandstone, intermingled with slaty coal and 



representing Brush creek coal of Pennsylvania 3' 



10. Sandy Shales 7' 



11. Loicer Mahoning sandstone, visible 85' 



12. Concealed to level of Cheat river. 10' 



No. 1 is the coal which so frequently occurs directly under the Oreen 

 Crinoidal limestone in south-west Pennsylvania and the adjoining regions 

 in West Virginia. It is quite impure and is well exposed at the roadside, 

 some distance north-west from Mr. Bayles'. 



No. 3 is the very persistent bed of red, marly shales which so constantly 

 underlie the Crinoidal limestone in Pennsylvania and West Virginia, even 

 retaining their place unfailingly in the series when the latter disappears. 



The Bakerstow7i coal, No. 6, occurs along the Morgantown road near the 

 toll-gate at Mr. Bayles*, and is of fair quality. I have identified' it with 

 the coal bed occurring 100' below the Crinoidal limestone, described as the 

 Bakerstown coal in my Report Q, on North Allegheny county, Pennsylvania. 

 These coals of the Barrens are of course sporadic and irregular in distri- 

 bution, and their identification over wide areas would seem at first thought 

 hazardous in the extreme, but as the principal beds always come in at cer- 

 tain well defined stratigraphical horizons there can be less objection to 

 such identification than to a constant multiplication of local names to repre- 

 sent the same geological horizon, hence as the coal in question comes 

 about 100' below the Crinoidal limestone, I have thought it preferable to use 

 the Bakerstown name even though the coal marshes in which each was 

 formed may never have been connected with one another. 



The Upper Mahoning sandstone. No. 8, is very conglomeratic at this lo- 

 cality, so much so that it was once extensively quarried for mill stones on 

 the opposite side of the river. 



The Brush creek coal is feebly represented in the section by a bed of 

 black coal slate interstratified with thin layers of sandstone, immediately 

 under the Upper Mahoning sandstone.
