TVABASH AND EDWAEDS COUNTIES. 57 



This seam has been opened by several parties in this neighborhood, 

 but the shafts have all been abandoned. This coal probably corre- 

 sponds to coal 11 or 12 of the general section. 



At Heeshey's old mill, on Eaccoon creek, there is an outcrop of the 

 same fossiliferous shales found at Lawrencevilie and Grayville, asso- 

 ciated with coal No. 11. The section here shows the following beds 

 outcropping in the bluffs of the creek : 



Feet. 



No. 1. Brown sandy shales and sandstone 8 to 10 



No. 2. Blue and gray shales, the lower part argillaceous 20 to 25 



No. 3. Blue fossiliferous shale, with iron nodules 3 



No. 4. Black laminated shale 1 to 2 



No. 5. Dark, hitnminous limestone to 2 



Ho. 6 Black laminated shale 1£ to 2 



No. 7. Blae clay shale 6 



The argillaceous shales No. 2 of the above section contain numerous 

 bands of argillaceous iron ore, which are more numerous in No. 3, and 

 contain the same species of fossils that occur in the shale. I obtained 

 here the following species : Pleurotomaria tabidata, P. sphwrulata, P. 

 Grayvillensis, Belleroplion carbonarius, B. per-carinatus, Polyphemopsis 

 per-acuta, Loplwphyttum proliferum, Dentalium obsoletum, Orthoceras 

 Rushensis, and Macrodon carbonaria. 



At Allendale this fossiliferous shale was found in a well sunk near 

 the railroad, overlaid, as at Hershey's mill, by sandy shales and sand- 

 stone, which is found in sinking wells in the higher portions of the 

 town. In one well near the summit level a thin coal 8 inches thick was 

 passed through, with 2 feet of clay shale above it, and about the same 

 thickness of fire-clay below. In the vicinity of Oriole the sandstone 

 above this thin coal is found at several places, and quarries have been 

 opened in it for building stone, flag-stones, etc. It probably underlays 

 all the highlands in the north-west portion of the county. 



At James McNair's well, one mile and a quarter north of Friends- 

 ville, the following beds were reported from memoranda furnished by 

 Mr. J. ZimiERHAN : 



Ft. In. 



Soil and clay 16 



Impure coal, (probably bituminous shale) 2 



Clay shale, with iron nodules - 3 



Hard sandstone 8 



Gray sandstone, in even beds, 4 to 8 inches thick 15 



Sandy shales . 11 



Hard sandstone in two layers 2 8 



Dark bituminous shale 3 



Coal, said to be good 2 



57 4 



At Mi\ Gilkerson's well, in the same neighborhood, after reaching 

 the coal found at the bottom of McNair's well, a boring was made to 

 the depth of 9 feet below the coal. The material obtained from the 

 boring was a milk-white substance resembling fire-clay.
