THE MINING AND QUARRY INDUSTRY IQIO O5 



Crushed stone. Limestone finds its principal application as 

 crushed stone in which forxii it is extensively employed for road 

 metal, concrete, and railroad ballast. There are large quarries in 

 Erie, Genesee, Dutchess and Rockland counties, besides a great num- 

 ber of smaller ones elsewhere that are equipped with crushing plants. 

 The recent canal and highway improvements have furnished a large 

 market for the material and the production has shown a steady in- 

 crease. The fine product that results from crushing is finding use 

 as a fertilizer for soils deficient in Hme. 



The value of the crushed limestone for 19 lo was reported as 

 $1,815,809 as compared with $1,744,314 for the preceding year. The 

 amount of the product was about 2,800,000 cubic yards. Erie 

 county led with a production valued at $476,490 against $447,605 in 

 1909. The other counties reporting values over $100,000 were 

 Dutchess, Rockland, Onondaga, Albany, and Genesee. 



Lime. The total value of lime made in 1910 was $365,839. This 

 branch of the industry experienced a poor season owing to the dull 

 conditions in the building trades. In the preceding year the value 

 was reported as $452,874. The lime made by the Solvay Process 

 Co. and the Union Carbide Co. has not been included in the totals, 

 but classed under " Other uses." The leading' counties in the manu- 

 facture of lime for the trade were Warren with a total value of 

 $140,576; Jefferson with $55,837; and Clinton with $48,823. 



Building stone. The limestones found in the State have only a 

 limited sale for building purposes, and few quarries supply more 

 than a local demand, so that their output fluctuates greatly from 

 year to year. The restricted market is probably due largely to the 

 fact that the limestones are prevailingly of dark or somber colors, 

 whereas the present demand is for the lighter colors like those of 

 the Bedford limestone and Ohio sandstone. The extending use of 

 concrete has also been a factor in the recent decline of the cut stone 

 trade, though it has increased the sale of crushed stone. 



The returns for 1910 indicated a total product of building stone 

 valued at $99,049 as compared with a value of $217,109 for the 

 preceding year and $245,655 for 1908. The loss was distributed 

 among various counties, but it was most apparent in Erie where 

 the output showed a falling off from a value of $119,134 in 1909 

 to $53,881 last year. The quarries in Schoharie and Herkimer 

 counties which have been notable producers in earlier years were 

 either inactive or were operated on a small scale.
