much farther east. It is characteristic, and forms one of the series 

 of the sahferous group, which underiies the whole of the Ohio val- 

 ley. It is most abundant in the vicinity of salines, except on the 

 Kenawha, ,where it terminates at the mouth of the Elk, a few miles 

 below. A trace of its general outlines, is given on the map of the 

 coal region. At all the places in which I have examined this rock, 

 (and they are many, and at remote points,) it has contained vegetable 

 impressions, and more or less imbedded nodules of the red oxide of 

 iron, which mineral, probably, imparts to it the rich brown, or red hue.
