I could not detect any trace of them in the bottom shale, and 

 so far as we can rely on the observations of the workmen, they 

 never occur there. Except Stigmaria, no fossil plants are 

 found in or near this bed of coal of Zanesville. But in the 

 Sandstones above and below the position of the coal bed, we find 

 many prints of well-preserved large Calamites and Lycopodendra, 

 from which, however, the carbonaceous matter has frequently 

 disappeared. 



In one bed of coarse Sandstone, these prints are remarkably 

 distinct, even in their minutest details. In a bed of while, soft 

 Sandstone, below the coal, and also in a stratum of ferruginous 

 Shale beneath the upper limestone bed, I found many fossil 

 forms of the same species with those met with in the Anthracite 

 Basins of Pennsylvania, namely. Aster opliyllites equisetiformis^ 

 Annularia, Neiiropteris cordifolia^ PecojJteris ccqualis, SjjJie- 

 nopteris, and others. The relative positions of these beds are 

 shown in the accompanying Sections, taken around Zanesville. 



FIRST SECTION. 



1. The highest strata capping the hills, Sandstone and Shales. 



2. Coal 4 to 6 feet thick, roof and bottom clays 1 to 2 feet thick. 



3. Coarse shaly Sandstone with prints of Lepidodendron, 3 to 5 feet. 



4. Ferruginous Shale 8 to 15 feet. 



5. Limestone 1 to 2 feet, with Terebratula, underlaid by a bed ofcoal or black 

 Shale 6 inches to 1 foot thick, containing prints of Calamites and Neuropteris 

 cordifoliai. 



6. Sandstone 6 to 8 feet. 



7. Limestone 1 to 2 feet. 



S. Sandstone rather thick ; this goes under the stream, west of Zanesville, on 

 the banks of the Muskingum River. 



SECOXD SECTION. 



1. Coal, traces of a bed capping the surface. A thin bed of soft, white Sand- 

 stone with many fossil plants. 



2. Sandstone 15 to 20 feet. 



3. Shaly Sandstone, Iron Shales, black and friable. 



4. Limestone 1 to 3 feet thick. 



5. Black slate and traces of a coal bed 6 inches to 1 foot thick. 



6. Shaly Sandstone 15 to 20 feet. 



7. Limestone 1 to 2 feet. 



8. Hard Sandstone 30 to 40 feet. 



9. Ferruginous Slates and Limestone passing under the water. 



Except in the thickness of the beds of Sandstone the corre- 

 spondence between the two sections is clear.
