peosseb.] LEHIGH RIVER SECTION. 17 
No. 1475 D— 1.— Hill southwest of Bartonsville, perhaps a half mile, 
is composed of coarse arenaceous shales in which fossils are very rare. 
As stated by Prof. White, the greenish gray sandstones of the Sta- 
rucca appear about 1 mile above Bartonsville, 1 and then sandstones and 
red shales alternate along the road until Tannersville is reached. 
No. 1475 D2. — The abrupt southeast side of Pocono Knob, northwest 
of Tannersville, is composed of red, arenaceous shales, No. 4 of Prof. 
White's Pocono Knob section. 2 
This shale belongs in the professor's "Cherry Bidge" group, and is 
in the upper part of his Catskill series. The arenaceous shale contains 
broken pieces of the fucoid ( ?) which is frequently found in the red 
arenaceous shales and sandstones of New York and Pennsylvania. 
Several specimens were seen on the talus below the brow of the knob. 
No. 1475 D3. — Above the shale is a conglomerate layer (White's 
lower conglomerate) followed by reddish sandstone and arenaceous 
shale, and then the upper conglomerate, which is a very massive 
stratum, containing quartz pebbles, and pebbles of the red and blackish 
shale. Prof. White reports u many fish fragments " from near the base 
of the lower conglomerate (No. 3 of the knob section); 3 but they were 
not found in my hasty examination of this locality. 
LEHIGH RIVER SECTION. 
In connection with the sections along the Delaware, Lackawanna 
and Western Kailroad, and the Pocono Creek through Bartonsville 
and Tannersville, it is interesting to compare one, farther southwest 
along the Lehigh Biver through Weissport and Bowmans station. 
Prof. White's geological map of Pike and Monroe counties 4 extends 
southwest of Monroe County into Carbon County and across the Lehigh 
Biver. Later, Arthur Win slow constructed a section from Wilkesbarre 
to the Lehigh Gap, mainly along the Lehigh Biver; and accompanying 
the report is a map, showing the geological formations along the line of 
the section. 5 
On Prof. White's map, Weissport is shown as situated mainly on an 
anticlinal of Hamilton rocks, just reaching the edge of the Genesee; 
the Chemung being exposed still farther to the southeast. In describ- 
ing the distribution of the Genesee shale, Prof. White states that one 
band reaches the Lehigh Biver, a short distance above Lehighton Sta- 
tion on the Central Bail road of New Jersey, and another crosses the 
river just below Lehighton Station on the Lehigh Valley Bailroad. 6 
The above description is repeated by Prof. Lesley in his final report. 7 
Mr. Winslow colored all of the central part of the anticlinal fold as
