it is of good quality, but the deposit has not yet been shown to be very 

 extensive. The shale over this coal contains a great number of very 

 beautiful impressions of fossil plants. 



AUSTINTOWN. 



This has been proved to be one of the richest townships of the county 

 in both coal and iron. It contains the southern extension of the Min- 

 eral Ridge belt of mines, which have now produced a large amount of 

 coal and blackband ore for many years. The principal mines of this 

 series are : 



Todd & Wells Coal Co.'s shaft, the Junction Coal Co.'s shaft, Baldwia 

 Bros, slope, Harris, Maury & Co.'s shaft, the New Lisbon Coal Co.'s shaft, 

 and Harroff Coal Co.'s slope. 



The sections of the strata overlying the coals as reported by the owner 

 of the different shafts, present some interesting variations which are 

 given below. The structure of the blackband basin, as indicated by the 

 sections of the shafts of Morris and Price, Todd and Wells, and the Junc- 

 tion Coal Company, is similar throughout, but the sections reported of the 

 Pennell and HarrofF slopes differ considerably from each other, and from 

 those of the mines further north.
