plants. The Waynesburg A and Washington coal beds are both thin, 

 and the latter is 160 feet above the Waynesburg at the only locality 

 for direct measnrenient. The section is longer in Perry township. The 

 Waynesburg passes under Dunkard creek at 8 miles west from the Monon- 

 gahela, and at barely 3 miles farther west, where the Waynesburg A 

 has passed under this succession, was found :

to the Washington coal bed, of which only the blossom was seen. The 

 interval between the Franklin limestone and the Washington coal bed 

 is about 280 feet; in Jefferson township, 9 miles east of north, it is 

 220 and in Franklin township, 9 miles west of north, it is 240 feet. The 

 Jollytown coal bed is very thin, not more than 6 inches. Doctor White 

 has published a section obtained two miles farther east, on Colvin run, 

 in which the Franklin limestone is 10 feet thick and 35 feet above the 

 Jollytown coal bed, which is 1 foot 6 inches; the Franklin is 281 feet 

 above the Washington coal bed. He finds a limestone 9 feet thick at 

 135 feet above the Franklin, which is evidently the same with that seen 

 in Jeiferson. As at that locality, the rock resembles the Nineveh in 

 several features, but the lessening interval in this direction seems to be 

 related to the conditions seen in western Wayne and in Gilmore, so that 

 on a preceding page this highest limestone has been referred tentatively 

 to the Jollytown horizon. In this section Doctor White finds 10 feet 

 of red shale very near the place of the Middle Washington limestone. 

 The Washington A coal bed, seen at several places here, as well as in 

 Whitely township, at the north, is 2 to 4 feet thick and so much broken 

 by shale as to be unimportant. The limestones are all thin and even 

 the Colvin is irregular, being only 3 feet on Colvin run. The Washington 

 coal bed, 5 feet 8 inches thick, is triple and its coal is poor. 



Doctor White measured a section on Dunkard creek, in Wayne town- 

 ship, which is almost the same with that obtained by Stevenson in Perry.
