QUARTZYTES AND SANDSTONES. 73 



should have been so productive a region. And if a part be of the 

 Oneonta or Portage, the remarkable fact comes out that they are in 

 the same geological horizon as the great quarries of Ohio stone 

 (Berea and Amherst). 



Beginning at the north-east, there are small quarries at Reidsville 

 and Dormansville, seven miles west of the Hudson river, and in Al- 

 bany county. They have furnished a great deal of stone for nagging 

 in the city of Albany. The stone of these quarries is gray in color 

 and rather coarser-grained than the typical blue-stone of the Hudson 

 river quarries. 



In Greene county there are several small quarries near Leeds, 

 which are worked mainly for the Catskill market. In the vicinity of 

 Cairo stone is quarried at several places, and shipped by rail. On 

 the line of the Stony Clove & Catskill Mountain railroad and along 

 the Kaaterskill railroad quarries have been opened, from the mountain 

 houses to Phoenicia. The quarries at Kiskatom and Palenville are 

 not so actively worked as in former years. Their stone goes to 

 Maiden, seven to nine miles distant. 



Ulster county is the largest producer of blue-stone, and the aggre- 

 gate output of its many quarries exceeds the combined product of all 

 the other counties in the belt or blue-stone territory. Its quarry dis- 

 tricts may be grouped as follows : 



1. Quarry ville, in the northern part of the town of Saugerties. 



2. West Saugerties, in the western part of the town of Saugerties. 



3. High Woods, in the town of Saugerties. 



4. Dutch Settlement, in the town of Kingston. 



5. Hallihan Hill, in the town of Kingston. 



6. Jockey Hill, in the town of Kingston. 



7. Dutch Hill, in the town of Kingston. 



8. Stony Hollow, in the town of Kingston. 



9. Bristol Hill, in the town of Hurley. 



10. Morgan Hill, in the town of Hurley. 



11. Steenykill, in the town of Hurley. 



12. West Hurley, in the town of Hurley.
