GUERNSEY COUNTY. 539 



The coal in this section, called the Anderson seam, from the owner of 

 a bank near Campbell's Station, is mined to a limited extent. The fossil- 

 iferous iron ore is doubtless the geological equivalent of the Cambridge 

 fossiliferous limestone found in the hills west of the town of Cambridge. 

 Near Hartford the following section was taken :

1. Limestone (Ames limestone), fossiliferous 1 



2. Notseen 18 



3. Blossom of coal.

5. Sandstone 20 



6. Shale 4 



7. Coal (Anderson seam) 2 6 



8. Not exposed 72 



9. Blossom of coal. 



(See Map XII., No. 17.) 



The Anderson seam of coal has been mined to supply a local demand. 

 The seams of coal of which only the blossoms were seen are elsewhere 

 generally quite thin, but they should be investigated. 



There is a strong antecedent probability that the Cambridge seam of coal 

 extends under all this township, and can be reached by shafts of incon- 

 siderable depth. . The only trial boring reported is one a little north of 

 Point Pleasant. Here, at a depth of fifty feet below the valley, the Cam- 

 bridge seam was reached, and reported to be six feet thick. 



BICHLAND TOWNSHIP. 



This township is situated east of Jackson.. It is drained by Wilis 

 Creek and its tributaries. The following section, taken at Senecaville, 

 shows many of the strata which make up the hills :
