1. Near Ryerson Station, western Greene County. Sample taken according to standard method (see 
p. 95); analyzed at fuel-testing plant, St. Louis 1 , Mo., by E. E. Somermeier. 
2. Near Taylorstown, Buffalo Township, Washington County; analyzed by A. S. McCreath (Second 
Geol. Survey Pennsylvania, Rept. K, 1876, p. 376). 
These analyses show a coal comparing very favorably with the 
Waynesburg bed. Usually, however, the quality is inferior to this, 
in respect both to ash and sulphur. 
JOLLYTOWN COAL. 
The name Jolly town was used by Stevenson in 1876 a for a coal 40 
to 50 feet below the Upper Washington limestone, and by I. C. White b 
in 1891 for a coal and limestone above the Upper Washington lime- 
stone. In the Waynesburg folio ( 1905) R. W. Stone followed Steven- 
son's use of the word, and that usage is maintained, as Stevenson had 
the right of priority. In the Amity quadrangle this coal is not known 
except at a few points in Amwell and West Bethlehem towmships, 
where it appears as a faint blossom 60 to 80 feet below the Upper 
Washington limestone. It has been reported up to 20 inches in 
thickness. 
TENMILE COAL. 
About 30 feet above the Upper Washington limestone there occurs 
in many places a thin coal bed which was erroneously called by I. C. 
White the Jollytown, but it is not equivalent to the Jollytown of Ste- 
venson, which occurs below the Upper Washington limestone. The 
name Tenmile coal is here suggested for this bed. The coal has been 
noted at a number of localities throughout West Bethlehem and 
Amwell townships, but is best developed south of Tenmile Creek. At 
several points it has been opened and found to reach a thickness of 1 
to 3 feet. About 2.2 miles w^est-southwest of Tenmile village a thick- 
ness of 38 inches was measured. The coal contains thin partings and 
occurs between a black shale and shaly sandstone.
