104 G 5 . REPORT OF PROGRESS. I. C. WHITE. 



In the northwestern corner of this township, the New Mil- 

 ford upper sandstone is seen near the house of Mr. C. Ste- 

 vens. It forms a line of cliffs around the hill and is 40' 

 thick, its base having an elevation of 1600' A. T. This is 

 most probably the same rock as the u Hinkerma Ledge" 

 north of Great Bend Depot, for its top comes here about 400' 

 above the base of the Catskill sandstone series, since, two 

 miles and a half north, the base of the New Milford Lower 

 sandstone is seen at 1250' above tide, and there is probably 

 very little dip in the intervening distance. 



Just south of the New Milford Upper sandstone ledge at 

 Mr. Stevens', we come to the base of another massive sand- 

 stone at 1785' A. T. a grayish-white rock and much current- 

 bedded. 



On the hill west from the Baptist Church near B. Lara- 

 bee' s, the outcrop of a white sandstone is seen capping the 

 summit at an elevation of 1840' A. T. ; it most probably be- 

 longs to the Honesdale sandstone group ; this is about the 

 elevation at which it should be found. Two hundred feet 

 lower, at this locality, we see the base of another massive 

 greenish gray sandstone. 



About one mile and a half north from this, near Yale 

 School House, a great sandstone mass is seen extending from 

 1625' to 1725' A. T. in several beds inters tratified with shales. 



Near the western line of the township, at Mr. L. Perry's, 

 a grayish-green sandstone is seen cropping out at 1600' A. 

 T. and extending up to 1650' at top. It would seem to rep- 

 resent the New Milford Upper sandstone but may possibly 

 be one somewhat higher in the series. 



Barometric elevations in Jackson.
