Stone, which Is so largely employed for flagging and house 

 trimmings In New York city, and to some extent In all of 

 our middle Atlantic coast cities and towns. "The belt of 

 country In which It is quarried is nearly one hundred miles 

 long in New York, stretching from the south-western towns 

 of Albany county, across Greene and Ulster and the western 

 part of Orange and eastern part of Sullivan counties to the 

 Delaware river. In Albany and Greene counties It Is nar- 

 row, as also in Saugertles In Ulster county, making the foot 

 hills, as it were, on the east and east-south-east of the Cats- 

 kill mountains, and bounded on the east by the older lime- 

 stone formations. It widens in the towns of Kingston, 

 Woodstock, Hurley, Olive and Marbletown, and In them 

 the quarries are distributed over the 500-foot plateau which 

 borders the mountains on the south-east. To the north- 

 west, and in the valley of the Esopus creek, many localities 

 near the line of the Ulster and Delaware railroad have been 

 opened and worked. They are a part of the blue-stone dis- 

 trict geographically, although the geological formations 

 are not the equivalent of the main belt at the south-east. 

 There are scattering localities in the towns of Rochester and 

 Wawarsing and thence south-west. In Sullivan county which 

 furnish blue-stone for local markets, and for exportation 

 where they are situated near enough to lines of shipping." 



The belt, as above described, has in It outcrops of shales 

 and sandstones, belonging to the several geological forma- 

 tions, from the Hamilton period to and Including the Cats- 

 kill, In short, rocks of the Upper Devonian age. There 

 are quarries along the Hudson river at New Baltimore, and 

 thence southward, at Coxsackie and Catsklll and near Ron- 

 dout, but they are not In the typical blue-stone, but In the 

 sandstone of the Hudson river slate formation. The quar- 

 ries of Palenvllle and vicinity, of West Saugertles, High 

 Woods, Boicevllle, Phoenicia, Woodland Hollow, Shandaken, 

 and Fine Hill are above the horizon of the Hamilton forma- 

 tion and probably all in the Catsklll group of rocks. The
