and road making, as building stone, and for construction purposes 

 generally, and in addition is an important material in chemical manu- 

 facturing and metallurgy. A large and increasing demand for lime- 

 stone has recently developed in connection with agriculture for 

 which purposes it is either burned into lime or ground into a fine 

 powder. 



The output of limestone has shown a steady gain during the last 

 four years and in 1913 it amounted to a value of $3,852,678, much 

 the largest on record. The total for 1912 was $3,510,445. These 

 figures do not show the value of the stone consumed in portland 

 cement manufacture which is a large item, or of any material quar- 

 ried by contractors on road improvement work, for which no reliable 

 data are obtainable. 



The statistical canvass for 191 3 showed a total of one hundred 

 four active quarries distributed among twenty-nine counties of the 

 State.

Erie county outranks all others in importance in this industry ; the 

 value of the limestone quarried in the county last year amounted to 

 $832,579. The products are chiefly furnace flux, crushed stone and 

 building stone. The principal quarries are at North Buffalo, Clar- 

 ence and Akron. 



Onondaga county is the second largest producer, with a total value 

 of $501,506 in 1913. A large proportion of the product is quarried 

 by the Solvay Process Co. for use as a reagent in the manufacture 

 of alkali. The quarries operated by the company at Jamesville are 

 very extensive and supply crushed stone as a by-product. A new 

 producer in 1913 was the Lackawanna Stone Co. with quarries in the 

 town of Onondaga.
