The shales resting on the coal are dark and contain a small quantity 

 of blackband, but ijisufficient to prove of economical value. The coal is 

 fairly compact and free from impurities, and is used in the village. It 

 varies in thickness from two feet six inches to two feet nine inches. 

 The sandstone of the section is exceedingly hard, and at times becomes 

 conglomerate. 



Madison Township. — In this township No. 7a is seen in the "bottom" 

 just east from Antrim, and there has been worked by stripping. It is 

 seen also in the bed of the run in section 11, at the township line. A 

 small amount of kidney ore is seen over it. At Antrim the Crinoidal 

 limestone lies at the level of the village, but no ooal is seen under it. 

 Near Winchester, on top of a ridge south of the village. Coal No. 8 has 

 been struck in wells. It showed a thickness of three feet, but is rotten. 

 No. 7a is not seen here, owing to the sharpness of the westward dip, 

 which carries it at least thirty feet under the creek at Winchester. 



No. lb is better developed here than in any other portion of the county, 

 and is worked to considerable extent. In the neighborhood of Winches- 

 ter it has been opened by G. W. Burson, J. H. Carlisle, Eli Titerick, and 

 others, and at a short distance south by P. Weyer and G. Yeo. At these 

 openings the coal lies at an average of five feet below the Crinoidal lime- 

 stone, and has a limestone not far below it. At Mr. Burson's opening 

 the following section was obtained: 



FT. IN. 



1. Crinoidal limestone 3 o 



2. Shale 4 



3. Cannel coal 11 



4. Bituminous coal 2 6 



5. Fire-clay 4 o 



6. Limestone 1 



7. Sandstone (seen) :.. 20 



The cannel coal varies from eight to eleven inches, and is full of avicu- 

 loid shells, which are so flattened and distorted that identification is 

 almost impossible. This material burns well and makes a good fire, but 

 leaves nearly half its weight of white, powdery ash. The bituminous 

 portion not infrequently attains a thickness of three feet four inches.
