STATE GEOLOGIST. 117 



A little further west,' at the village of Barry, the coal is 

 found again outcropping and has been worked to a considerable 

 extent by the Jackson City Coal Company. The coal possesses 

 nearly the same qualities here as at Woodville, though what I 

 saw seemed to be of a less solid character. Some specimens 

 were furnished me, however, for exhibition at the State Pair, 

 which, in physical characters, appeared equal to any in the 

 State. 



The geology of this vicinity is exceedingly complicated — the 

 carboniferous limestone and overlying Parma Sandstone appear- 

 ing at points north-east and north-west of the mines, at a higher 

 geographical position than the coal. There can be no doubt 

 that these mines are also situated on an outlier of the coal 

 basin, of but limite"d extent 



An outcrop of coal is said to occur about half a mile west of 

 the village of Barry, East of here the eoal is seen again out- 

 cropping in the bank of the Grand River at the mill-dam in the 

 ■ city of Jackson, and indications of its approach to the surface 

 are seen at several other places in the neighborhood. Borings 

 and excavations have been made at various points, with no uni- 

 form results. In the shaft which was sunk by the Jackson City 

 Coal Company, the following section was passed, according' to 

 the statement of Mr. William Walker: 



G. Superficial materials, 3 ft. 



F. Sandstone, white or slightly stained, banded below with 

 ferruginous ancfr argillaceous streaks; contains Cala- 

 mites and carbonaceous matter, ' 26 ft. 



E. Black bituminous shale with Lingula, 14 ft. 



D. Black band iron ore, with abundance of Lingula, 3 ft. 



C. Cannelcoal, 2 ft. 



B. Bituminous coal, 2 ft. 



A. Finely arenaceous fire clay, with abundance of Stig- 



marice, T ft. 



In the boring close by, the section continues downward 

 through 30 feet of arenaceous materials, probably representing 

 the Parma Sandstone. 



Numerous explorations have been made in the. vicinity of the
