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



seen by me in this rock throughout the country north of 

 Honesdale ; but going south and southeast it becomes a 

 regular conglomerate, as on the hilltop east of White's Mills. 

 Exposures can be found nearly up to the New York State 

 line ; its last outliers on the northward rise being in Scott 

 township. In Middle Susquehanna county I saw it occa- 

 sionally capping hills ; but not so readily distinguishable 

 from the other Catskill rock, as in Wayne county. 



Montrose red shale (11), 180' thick. — This is seen along 

 all the principal streets of the borough, wherever cuttings 

 have been made, and is especially well exposed on the road 

 descending the Wyalusing creek. It is equally evident on 

 the hill roads around Honesdale ; and the upper part of it 

 just under the sandstone cliffs makes a great red show from 

 afar. Two thirds of the mass, at least, in the Montrose 

 country consists of red shale ; the rest of several interca- 

 lated beds of gray sandstone. Around Honesdale there is 

 at least 150' of red shale ; the rest being intercalated gray 

 sandstones. 



The Honesdale ' ' copper and nickel shale' ' of the old re- 

 ports lies at the very top of the red shale mass. 



Paupack sandstone (12), 25' thick. — From large quarries 

 in this beautiful, bluish-green, serpentine-like rock, the silk 

 factory at the mouth of Paupack, and churches in Hones- 

 dale have been built. It is probably confined to Southern 

 Wayne county, for I found nothing to correspond to it else- 

 where in the region. 



About 200' of greenish -gray, current-bedded sandstones, 

 interstratified with green, olive, and occasionally red shales, 

 underlie the Paupack quarry rock, and spread throughout 

 the district in a manner so uncharacteristic that I hesitate 

 to propose a name for these deposits.
