166 G 5 . REPORT OF PROGRESS. W. O. PL ATT. 



Just west of Tylerville a band of calcareous conglomer- 

 ate, 2' thick, is seen about four hundred feet below the last. 



Just across the Delaware river, on the New York side, at 

 Narrowsburg, a hole was once bored for oil to a reported 

 depth of 800' ; its top was on the bluff about 25' above the 

 channel of the stream. No record could be obtained of 

 it, and very contradictory statements were given me con- 

 cerning its depth ; all that can be safely asserted, is that 

 some gas was struck at an uncertain depth, since all the re- 

 ports agree in this. If the well were really drilled to a depth 

 of 800' it must have penetrated the Chemung rocks to a con- 

 siderable depth unless the Catskill greatly thickens south- 

 ward. 



As we pass westward from Narrowsburg up on to the high- 

 lands, many bold outcrops of massive cliff sandstones occur. 

 One, more massive than usual, is seen near Branningville 

 with its base at 1015' A. T. ; it is grayish- white in color and 

 about 3(r thick. 



Farther east from Branningville, we see the same stratum 

 45' thick, and above it (at 1105' A. T.) we see the base of a 

 coarse gray sandstone, in which occur many small angular 

 pebbles of white quartz. 



West from this near J. Sprook's we see a cliff sandstone 

 beginning at 1375' A. T. and extending up to 1425' at the 

 summit of the hill.
