pross'er.1 POCONO SECTION. 15 
Chemung, between the Montrose sandstone above and the Montrose 
red shale below, 1 which is at a part of the series not distant from the 
horizon in which the Spin/eras were collected above Henry ville. 
Above this horizon coarse, gray sandstones and shales alternate with 
reddish shales. A thick mass of the red shale is well exposed in the 
railroad cut just west of Oakland. The cut below Mount Pocono shows 
coarse, gray sandstone with fragments of fossil plants, thin, bluish, 
argillaceous shales, breccia, and red shales, while in places the coarse, 
gray sandstone contains quartz pebbles, and is probably near the hori- 
zon of Prof. White's Cherry Ridge conglomerate, about 500 feet below 
the top of the Catskill. 2 
In general structure and lithologic appearance, these rocks are very 
similar to the typical Catskill of the Catskill Mountains. 
On the summit of the.Pocono plateau, about 2h miles north of Toby- 
hanna, is a massive conglomerate which is considered by Prof. White 
as the Mount Pleasant conglomerate at the base of the Pocono. 3 
POCONO CREEK AND POCONO KNOB SECTION. 
After the section along the line of Brodhead Creek and the Dela- 
ware, Lackawanna and Western Railroad had been studied, another 
one was made from Stroudsburg along Pocono Creek, through Bartons- 
ville and Tannersville to Pocono Knob. The same series of formations 
was crossed by this latter section as by the former; but in general the 
exposures are not so good, and the conditions not so favorable for a 
careful study of the stratigraphy and palaeontology of the region. 
However, the general results were about the same, as will be seen 
from the lists of fossils and descriptions of different localities. 
No. 1475 D — 2. — On the highway from Stroudsburg to Bartonsville, a 
little below the Tanite Company's mill, is an outcrop of bluish, arena- 
ceous shale, which is quite fossiliferous, Tellinopsis subemarginata (Con.) 
Hall, being the most abundant species.
