rock in Onondaga and Schoharie counties. The purer limestones 

 of the group are employed in Onondaga county for lime making. 



At the base of the Devonic system, the Helderbergian group 

 is prominent for its limestones. The latter are strongly developed 

 along the Hudson river in Albany, Columbia, Greene and Ulster 

 counties. The Coeymans or Lower Pentamerus formation affords 

 rock suitable for lime, building stone and road material, while the 

 Becraft or Upper Pentamerus is employed as an ingredient of 

 Portland cement and for furnace flux. There are quarries at 

 Hudson, Rondout, South Bethlehem and Catskill. 



Of the remaining formations represented in New York, the 

 Onondaga is the only one that is of much importance for lime- 

 stone quarries. It outcrops in Orange, Ulster, Greene and Albany 

 counties, and is exposed quite continuously through the middle 

 and western part of the State. Building stone and lime are the 

 principal products. Quarries have been opened at Kingston, Split- 

 rock (near Syracuse), Auburn, Waterloo, Seneca Falls, Leroy and 

 Buffalo, and many other places. 



Production of limestone 



The value of the limestone quarried in New York during 1904 

 amounted to $2,058,405. This is exclusive of the limestone used 

 in making Portland and natural cement, for which no statistics 

 have been collected. There were 35 counties that reported an 

 output with 157 quarries in all.

Crushed stone, for road metal, concrete and other purposes, 

 represented the largest item in the production, the value of this 

 material being $994,475, or 48% of the total. The manufacture 

 of lime was second in importance with a yield valued at $678,225. 

 Building stone was quarried to the extent of $248,647. The re- 

 maining uses reported for the product were furnace flux, which
