WASHINGTON COAL. 



The Washington Coal, first described by White 9 as the 

 Brownsville Coal from a town of that name in Monongalia

 the subject of "Coal." Its outcrop is shown on Map II. 



WASHINGTON FIRE CLAY SHALE.

 and Gilmer. It is usually about 30 feet thick, yellow and some- 

 what sandy in the lower portion, but having a decidedly green- 

 ish tinge at the top, just below the Washington Coal, making 

 a valuable marker in searching for the latter horizon. In 

 Chapter IV it is noted in the sections for Bennett, Cedarville, 

 Conings, Copley, Gaston, Gillooly, Hurst, Latonia, Newberne,
