be beneath the railroad. A massive sandstone occurs below grade at this 

 point, and this may cut out the lower coals; the exposures are too imper- 

 fect to decide this question. 



POBT HOMER. 



At Port Homer the following section was obtained on the farm of Mr. 

 Desellems : 



1. Shale and sandstone 50 feet. 



2. Crinoidal limestone 4^ feet. 



3. Oliveandredshales, with some sandstone 158 feet. 



4. Coal 6 inches. 



5. Shale 40 feet. 



6. Coal IHo. 7 - 18 inches to 3 feet 8 inches. 



7. Sandstone, clay, and shale.. 40 feet. 



8. Non-plastic fire-clay, with plastic clay 1^ to 3 feet. 



9. Shale and sandstone 47 feet. 



10. Coal No. 5 20 inches. 



11. Fire-clay 1 foot. 



12. Concealed - 75 feet. 



13. Gray shale, with nodular iron 15 teet. 



14. Coal No. 3 — "clay seam" — 3 inches of cannel 



at bottom 3^ to 4 feet. 



15. Fireclay 8 feet. 



Cleveland and Pittsburgh Bailroad 45 feet above river. 



Port Homer is the first point below the mouth of Yellow Creek where 

 the " Clay coal" ("Creek Vein," or Coal No. 3) has been identified. It is 

 here worked for household purposes, but is a very inferior coal. A trace 

 of No. 4 is found twenty to thirty feet above it, but it is not well seen 

 here, and is probably thin. A twenty inch seam ninety feet above Coal 

 No. 3 is probably Coal No. 5, although the exposures are insufficient to 

 determine this. The seam ninety feet above that last mentioned, is ap- 

 parently Coal No. 7, the place of No. 6 being half way between the visible 

 coals. No traces of it were discovered, and it may be wanting. The in- 

 terval is too incompletely shown to decide the question. 



// m'coy's station. 



From Port Homer the strata are nearly horizontal to McCoy's. They 

 slightly rise towards the south, indeed, as the fire-clay under No. 3, on 

 the grade at Port Homer, is at McCoy's five or six feet above the railroad. 



As shown in the section made at Port Homer, a hard non-plastic fire- 

 clay, similar to the Mineral Point and Mt. Savage clays, occurs about one 

 hundred and fifty feet above the railroad. It is associated with plastic 

 clay and recurs -in many of the sections taken in this vicinity. Its thick- 

 ness is variable, reported from eighteen inches to ten feet, but no good
