Lower Coal Measures.—Brown. 995 
near Eighty Cut, at 1860 ft, A. T., it passes into the air and is 
seen no more on the western side of the Allegheny mountains. 
The whole length of this section, embracing one great anticline, 
one syncline, and reaching to the crest of another anticline, is 
about 30 miles, and along it in several places complete sections 
of the Lower Coal Measures are exposed. 
Between the Mahoning sandstone and the Upper Freeport coal, 
near the river, there are usually about 40 ft. of dark colored 
shales, that in places yield numerous fossils, but on going east 
these shales rapidly thin out, and the sandstone then lies immedi- 
ately upon the coal, forming an excellent roof. 
On ascending White Day creek to Garlow’s mill we find the Lower 
Coal Measures fully exposed and the section shown in cut No.2 was 
obtained there. The Mahoning sandstone here lies immediately 
upon the Upper Freeport coal. The section reads as follows:
