COAL. 113 
In Somerset Township, on North Branch of Pigeon Creek, the coal 
outcrops with the following section : 
Section of Waynesburg "A" coal in Somerset Toumship. 
Ft. in. 
Sandstone 10 
Coal 10 
Clay 4 
Coal, slaty 5 
Clay 2 
Coal and shale 1 4 
The Second Survey states that the Waynesburg "A" was once 
opened in West Bethlehem Township 1^ miles northwest of Scenery 
Hill, but the thickness was only 15 inches. 
WAYNESBURG "b" AND LITTLE WASHINGTON COALS. 
These names have been applied at various times to thin coals occur- 
ring between the Waynesburg "A" and Washington beds in various 
parts of Greene and Washington counties. It is true that blossoms 
have frequently been found in this interval, and in one or two instances 
thicknesses as great as 1 to 2 feet have been reported, but it can be 
safely said that neither of the beds is of any value. 
WASHINGTON COAL. 
The Washington coal is known from the locality of its typical occur- 
rence. It is 110 to 160 feet above the Waynesburg coal and directly 
below the Lower Washington limestone. This coal is much more per- 
sistent than any other coal bed of the Dunkard group, and reaches in 
many places a thickness of several feet, although on account of its 
numerous shale partings it is of little commercial value. At no point 
in the Amity quadrangle is the bed now worked, but conspicuous blos- 
soms usually occur wherever its horizon crosses a road. 
THICKNESS. 
In the vicinity of Washington the coal is exposed at a number of 
points and locally reaches a thickness of 7 feet. It usually consists of 
many divisions of coal and shale. One of the best exposures to be seen 
is that in the Baltimore and Ohio Railroad cut just off the quadrangle 
in the western part of Washington. The coal is here 7 feet 1 inch 
thick and is overlain at a few feet by the Lower Washington limestone. 
The coal is subdivided by bands of clay, as shown in fig. 6, No. 14,
