 It is probably thin.

SPENCEE TOWNSHIP. 



This township lies in the south-western part of Guernsey county. It 

 is drained for the most part by Buffalo Creek, a branch of Wills Creek. 

 The only coal worked is the Cumberland seam. The blossom of the 

 Pomeroy seam was seen, but so far as could be learned the seam is not 

 mined. It is probably quite thin. The following section contains the 

 Cumberland coal seam found on the land of Mr. H. C. Hunter, a mile 

 from the town of Cumberland, on the road to Caldwell :
