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



The uppermost member of the section, together with the 

 dam at Wilsonville, makes a cascade of 20' at that locality, 

 and then the stream descends in a series of rapids until the 

 top of No. 7 is reached, when in three successive leaps, in- 

 cluding the rapids between, it descends a vertical height of 

 145' in a horizontal distance of about 100 yards. As the Pau- 

 pack carries a considerable volume of water at all seasons of 

 the year, this is the finest site for water power in the coun- 

 ty. Strange enough it has hitherto been allowed to run to 

 waste with the exception of a small modicum utilized by a 

 tannery and nouring-mill. There is now, however, a large 

 silk manufactory in process of construction, which takes its 

 water power from the top of the first cascade, and thus gets 

 the pressure of a column of water 50' high on its turbine 

 wheel. There is still plenty of room and power for other 

 factories on each bank of the stream. 



The only member of this section to which any especial at- 

 tention need be called is the stratum which I have designated 

 from this locality, the Paupack sandstone, a greenish gray, 

 or sometimes bluish green rock, extensively quarried along 

 the banks of Paupack one fourth mile above the first cas- 

 cade. It comes in layers 4" to 8" thick and was used in build- 

 ing the silk factory at the "falls ; " it very much resembles 

 the quarry rock in the hill opposite Honesdale. and is doubt- 

 less the same stratum ; elevation 1050' A. T. ; (25 / higher than 

 the top of the Honesdale rock, ) but this is in favor of their 

 identity, since there is a slight rise in the rocks southward 

 between Honesdale and Hawley . It makes a beautiful build- 

 ing and from a short distance very much resembles the Ser- 

 pertine structures of Philadelphia. 



A short distance below Wilsonville a great bed of Drift is 

 seen at the roadside 1090' A. T.
