generally throughout both counties in oil well records where 

 it is called the "Little Dunkard Sand" by the drillers. In 

 northern Lewis it crops only at Jackson Mill where 5 feet 

 of its top is exposed above drainage, as shown by the section 

 for that place published in this Chapter. In southern Lewis 

 it crops generally throughout Collins Settlement District. In 

 this region it is usually gray, hard, massive and coarse. 



The Morgan Galford Quarry, located on Right Fork of 

 West Fork River, 1.2 miles south of Walkersville, shows the 

 following section :

Shale, variegated ..................................... 10 



Here the stone is coarse, and only medium hard, massive 

 and gray, having irregular joint and bedding planes. The 

 quarry is 50 feet long and extends into the hiil 30 feet, its 

 product having been used for bridge abutments. 



The Buffalo Sandstone is a prominent feature along the 

 Coal and Coke Railway grade between Wymer and French- 

 ton, the railroad grade and the eastward rise of the strata 

 being almost equal. The numerous cuts reveal good exposures 

 of the sandstone and the underlying Brush Creek Limestone 

 and Coal. 



THE BRUSH CREEK LIMESTONE AND SHALE. 



The Brush Creek Limestone of White 21 and the Brush 

 Creek Shale of Hennen 22 , occupying about 10 feet of the mea- 

 sures between the Buffalo Sandstone and the Brush Creek 

 Coal, crop only in the eastern part of Collins Settlement Dis- 

 trict, Lewis, where they are of frequent occurrence, most of 

 the exposures revealing only shale. This shale, which is dark 

 gray or black, usually carries marine fossils, crinoids being 

 much in evidence. It is well exposed along the Coal and Coke 

 Railway grade between Wymer and the Frenchton Tunnel. 

 The following section, measured 0.8 mile east of Wymer, 

 shows the succession :
