under the stream. Along this road the following section was observed, 

 which is very imperfect above, but fully exposed below: 



FT. 



1. Shales and sandstones, badly exposed 110 



2. Goal, blossom, 



3. Sandstones, with some limestone 100 



4. Limestone and calcareous shale , 60 



5. CoalKo.So — shale,2feet; coal, 2 feet 4 



6. Sandstone 20 



7. Limestone 15 



8. Coal No. 8a 1 



9. Limestone and calcareous shale.. 30 



10. Shale 5 



11. Coal No. 8. 



In the little stream running by the plank road, Coal No. 8c has been 

 taken out. The available thickness is about fourteen inches, and the coal 

 is of moderately good quality, though much injured by numerous thin, 

 slaty partings. The faces are covered by thin films of carbonate of lime. 



Going norlh-west from Mt. Pleasant, on the Cadiz pike, we find the fol- 

 lowing section, which presents some interesting variations from the last : 



FT. 



1. Arenaceous shale 15 



2. Coal No. 12, blossom. 



3. Arenaceous shale 50 



4. CoalNo. 11, blossom 2(J) 



5. Concealed in part, but most sandstone, with occasional layers of flaggy 



limestone 115 



6. Limestone and calcareous shale 40 



7. Argillaceous shale 3 



8. Coal No. 8c, blossom 1 



9. Thinly laminated arenaceoas shale.. 18 



10. Limestone, gray, ferruginous — weathers yellow 15 



11. Coal No. 8a, blossom 8 



12. Limestone and shale 18 



13. CoalNo.8 6 



In these sections, Coal No. 8&, of the Belmont county section, which 

 should overlie No. 7 of the first and No. 9 of the second, is absent, as is 

 also Coal No. 9, which should rest on No. 4 and No. 6 of the two sections. 

 It is well worthy of note that the limestone under Coal No. 9 has lost 

 twenty feet of its thickness within three miles, while the interval between 

 8 and 8c has lessened about thirteen feet. 



On Long Run, where the base of the last section is reached, Coal No. 8 

 has been mined quite extensively, but many of the openings have been 

 deserted, or are now lying idle. In the banks of Messrs. Orubbs, Kith-
