The proportion of asli is generally large, but the coal is reported to 
burn freely and to be marketable. In West Virginia it is a valuable 
coal. 
UNIONTOWN COAL. 
The Uniontown coal is a bed occurring at an average interval of 230 
to 260 feet above the Pittsburg and 40 to 80 feet below the Waynes- 
burg, just above a characteristic yellow limestone. It is present in 
many places as a distinct blossom, but is everywhere thin and is not 
persistent in this quadrangle.
