Production of limestone . 



Limestone is quarried in 35 counties of the State with a total of 

 about 160 active quarries. The value of the production last year 

 amounted to $2,411,456. This is exclusive of the limestone used 

 in the manufacture of Portland and natural cement, for which no 

 statistics have been collected. Compared with the preceding year, 

 there was a gain of $307,361 in the production.

Crushed stone for road metal, railroad ballast, concrete and other 

 uses, represents the largest item in the output. The value of this 

 material was $1,193,800, against $994,475 for 1904. The manu- 

 facture of lime is second in importance with a product valued at 

 $702,684 and $678,225 for the respective years. The building 

 stone quarried amounted in value to $246,300, against $248,647 in 

 1904; furnace flux to $198,168, against $121,109; rubble and riprap 

 to $40,664, against $22,230 ; flagging and curbing to $7297, against 

 $6253 ; and miscellaneous materials, not classified in the returns, 

 to $22,543, against $33,156 in the preceding year. 



Distributed according to the counties in which the limestone was 

 quarried, the largest producer last year was Erie county which had 

 an output valued at $383,411, consisting principally of building 

 stone, crushed stone and furnace flux. Onondaga county which 

 was first in 1904 ranked second last year with an aggregate of 

 $310,322, mainly represented by lime manufacture. The remaining 

 counties which reported a total value of over $100,000 each were 

 Dutchess, $234,578; Genesee, $227,087; Rockland, $220,596; War-
