Further in the drift we observed : 



Coal, 6 inches. 

 Clay, I foot. 

 Coal, lo inches. 



One and a half miles north the coal is separated by five inches of blue clay 

 shales, and a thin limestone band is insinuated in the overlying clay shales. 

 Sandstone crops out above. Twenty-five feet below the coal we here observed 

 layers of ferruginous limestone conglomerated in three layers of 6 inches, 4 

 inches and 8 inches with 4 feet of clay shales beneath. One mile still further 

 north the coal and its associated rocks appear thus : 



1. Thin layers of deep blue limestone. 



2. 2 inches roughly bedded limestone. 



3. I foot of drab calcareous shales. 



4. 20 inches of deep ash-blue pyritiferous limestone, containing re- 



mains of crinoidea including fragments of Zeacrinus microspinus. 



5. 2 to 6 inches brown calcareous shale. 



6. 10 inches coal. 



7. 4 inches blue laminated shales. 



8. 9 inches coal. 



9. 2 feet fire-clay. 



A quarter of a mile west observed as follows : 



1. 4 feet blue clay shales. 



2. 6 inches blue limestone. 



3. 6 inches brownish gray calcareous shales. 



4. 4 inches of limestone — No. 4 of last section. 



5. 5 inches brown shale. 



6. 9 inches coal with thin coal seams. 



7. 4 inches blue clay. 



8. 5 inches coal. 



A quarter of a mile northwest we still find some changes with the following 

 section : 



1. 2 feet brown and drab limestone. 



2. 6 feet of dark shale, the lower i ^ feet thinly laminated bitumin- 



ous shales. 



3. o to I foot blue concretionary limestone. 



4. 10 inches thinly laminated calcareous shales and concretionary 



limestone. 



5. 3 feet sandy and clay shales. 



6. 6 inches blue clay shales. 



7. 10 inches coal. 



8. 4^ inches clay. 



9. 6 inches coal.
