THE MINING AND QUARRY INDUSTRY 1915 65 



Erie county has the largest industry of any; the value of the 

 output quarried in the county in 191 5 was $601,465. Its products 

 chiefly are crushed stone, furnace flux and dimension stone. The 

 quarries are situated in North Buffalo, Clarence and Akron. The 

 Kelley Island Lime and Transportation Co. sold its quarry at 

 Akron to the General Crushed Stone Co. 



Onondaga county is second in rank as a producer and last year 

 reported an output valued at $495,004, which was larger than in 

 191 5. The quarries are situated in the Onondaga and underlying 

 formations which stretch across the county south of Syracuse. One 

 of the largest quarries is that of the Solvay Process Co. which uses 

 the product largely in their alkali works at Solvay near Syracuse. 



Other counties reporting values of over $100,000 in 191 5 were 

 Niagara, Dutchess, Genesee, Rockland, Ulster, Warren and West- 

 chester, named in order of their rank. 



Crushed stone. This item includes road metal, railroad ballast 

 and concrete. The larger quarries supplying these materials are 

 in Erie, Genesee, Onondaga, Dutchess, Ulster, Rockland and West- 

 chester. The " fines " from some of the crushing plants are sold 

 for agricultural use, the sales being entered under " other uses." 

 The value of the crushed stone for 191 5 showed a small decrease, 

 as compared with that reported for 1914, and totaled $2,072,852, 

 against $2,156,503. The total does not include stone crushed by 

 contractors on the highway system, but the value of such stone is 

 relatively small. The quantity of stone reported by the crushing- 

 plants was 2,985,347 cubic yards, against 3,306,325 in 1914. 



Lime. The value of the lime made for the market last year was 

 $387,083, as compared with $370,377 in 1914. In quantity the 

 product amounted to 83,627 short tons, against 82,944 short tons in 

 1914. The greater part of the output w T as building lime, but a 

 considerable proportion consisted of material for paper and 

 chemical purposes and agricultural lime. A new T feature of the 

 trade was the inquiry for magnesian limes to supply the place of 

 imported magnesite, especially for the manufacture of refractory 

 furnace linings. The supply of magnesite which formerly came 

 from Austria and Greece has been practically cut off by the 

 European War, and manufacturers have resorted to dolomite as a 

 substitute. One quarry in the Adirondack region made a speciality 

 of magnesian lime for the purpose named. The principal lime 

 burners are in Warren, Washington, Clinton, Fulton, Lewis and 

 Dutchess counties.
