and Susquehanna. His section for those counties, condensed and 
re-arranged is* 
CATSKILL. 
Cherry Ridge shales 110’ 
Honesdale sandstone 90’ 
CHEMUNG. 
Montrose red shales 180/ 
Paupack sandstone and shales, New Mil- 
ford flags and shales 585’ 
Shales and sandstones 244’ 
“Mansfield Reds” 90’ 
(Allegrippus) Cascade Creek sandstone 20 
Shale and sandstone 120’ 
The lower portions of the colfimn are not exposed in the coun- 
ties. The Paupack sandstone, immediately underlying the Mont- 
rose shales, occupies the position of the Lachawaxen conglom- 
erate, but it is not seen as a conglomerate except in eastern 
Wayne, on the border of Pike county. The Cascade Creek 
sandstone is the same with the Falls Creek sandstone of Brad- 
ford county, and with the <A/legrippus conglomerate of Bed- 
ford and Huntingdon counties, the Lower Chemung conglom- 
erate of Fulton county. A great part of the interval be- 
tween these sandstones is represented further east by the Dela- 
ware flags. For the most part, this is the section observed along 
the Delaware river in Pike county of Pennsylvania, and in the 
adjacent portion of New York; and the Honesdale sandstone is 
the Montrose sandstone of Vanuxem.t Prof. White made dili- 
gent search for fossils, but no mollusks were found at any hori- 
zon more than 130 feet above the Allegrippus; but Chemung fos- 
sils are sufficiently abundant below that rock.  Archwopteris 
jackson’ occurs in the Paupack or Lackawacxen., 
Tit. : 
We have come once more to the Delaware river, the last point 
reached in the tracing of the easterly outcrop. Clearly the 
series is one: the middle portion, that between and including the 
two conglomerates, is evidently persistent all the way round, except 
perhaps in McKean and Potter counties of Pennsylvania, where, 
however, the difficulty lies most probably not in absence of the 
sub-group but in the absence of records.

Harrisburg, 1881. pp. 56, 58, 59,73. In accordance with Prof. White’s 
suggestion (Geol. of Susquehanna R. Region, p. 52,) I have omitted the 
upper 375 feet of the section.
