 nearly tho same qualities b I Woodvillc, though what I 



gawsecmid to be solid charac I me specimens 



were furnished mo, however, for exhibition at the State Fair, 

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

 State. 



The geology of this vicinity is exceedingly complicated — tho 

 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 arc also situated on an outlier of the coal 

 basin, of but limited extent 



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

 the village of Barry East of here the coal 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 

 sen 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. SuporhYi.il materials 3 ft 



• •;dstone, white or slightly stained, banded below with 

 ferruginous and argillaceous streaks; contains Cala- 

 miles and carb matter 20 ft. 



E. Black bituminous shale with Linyula, 14 fL 



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

B. Bitum .1 2 ft. 



A. Finely arc . with abundance of Stig-

In the boring close by, the section continues downward 

 through 30 feet of arenaceous m ably representing 



the Parma Sandstone.
