Altogether 91 quarries reported an output, as compared with 104 

 in 191 3. There were 29 counties represented in the industry. 

 There were no new quarries of any importance opened during the 

 year. 



Erie county outranks all others in importance in this industry; 

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

 to $704,865. The products are chiefly furnace flux, crushed stone 

 and building stone. The principal quarries are at North Buffalo, 

 Clarence and Akron. 



Onondaga county is the second largest producer, having an out- 

 put last year valued at $385,335. Crushed stone is a large item 

 in its industry, and most of the remainder consists of limestone 

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

 manufacture. 



The other counties reporting values of over $100,000 in 1913 

 were Dutchess, Ulster, Niagara, Rockland, Genesee, Warren, Scho- 

 harie, Clinton and Albany counties, named in the order of their 

 output. 



Crushed stone. Limestone is crushed for road metal, railroad 

 ballast and for concrete. The larger quarries supplying this material 

 are in Erie, Genesee, Onondaga, Dutchess, Ulster, Rockland and 

 Westchester counties. The fines from some of the quarries are 

 sold for agricultural use, the sales being entered under " other 

 uses." The value of the crushed stone for 1914 showed a decrease 

 due to the smaller demand in the building trade, and totaled 

 $2,156,503, against $2,386,632 in the preceding year. The total 

 does not include stone crushed by contractors on the highway sys- 

 tem, but the value of such stone is relatively small. The actual
