The Upper Frccport coal given iu this section, has been opened along the 

 road on the land of Mr. Graham, about one mile south-west from the top 

 of the river bluff at No. 3, so that the interval of 200' between the coal and 

 No. XII, given by the barometer, should very probably be increased by 

 50'-7o', since the beds decline in that direction (S. W). 



As we pass on south-eastward up Cheat river from the Falls, the rocks 

 still continue rising gently for about two miles, when they turn over in 

 the broad arch of Laurel Hill, and descend, carrying the limestones and 

 shales of No. XI below river level, and finally submerging No. XII 

 itself at Albright, in the centre of the trough, where the western blufi of 

 the river reveals the following section (14) of the Lower Coal measures : 



1. Sandstone, somewhat massive, Mahoning ? 30' 



2. Concealed 55' 



3. Shale, drab 15' 



4. Sandstone 2' 



5. Shale and fireclay 8' 



6. Shale, green, sandy 10' 



7. Sandstone, gray, massive, Freeport 30' 



8. Shale, drab 15' 



9. " dark blue 8' 



10. Coal, Middle Eittanning {Darlington) ,. .2'-3' 



11. Concealed 5' 



12. Limestone, nodular, {Johnstown cement bed) 2' 



13. Concealed 23' 



14. Sandy shale 7' 



15. Sandstone, greenish 13' 



16. Shale, visible 5' 



17. Concealed to level of Cheat river at Albright bridge 



(1200' A. T. Bar), and to top of No. XII, here in 

 bed of river 25' 



Total height of section 255 



From the thickness of the measures in the above section, it would 

 seem that the Upper Freeport coal should be looked for immediately 

 under the base of No. 1, which according to this identification would be the 

 Lower Mahoning sandstone, but still it is possible that the Lower coal meas- 

 ures are here thicker than usual on Cheat river, and in that event the 

 Upper Freeport coal would overshoot the top of this section. 



No. 7 is undoubtedly the representative of the Freeport sandstone of 

 Pennsylvania, while the coal. No. 10, would seem to be the Middle Kit- 

 tanning, or Darlington led of Western Pennsylvania, if Mr. Franklin 

 Piatt's identification of the latter with the coal overlying the Johnstown 

 cement bed be correct ; for the coal in question is here underlain by a 

 grayish, nodular limestone that would well represent the "cement bed." 



The coal is quite good and has been gouged out of the hill to the depth
