Crushed stone. The use of crushed limestone for road metal, 

 concrete and railroad ballast is constantly increasing. Large, well 

 equipped crushing- plants in Erie, Genesee, Dutchess and Rockland 

 counties are turning out enormous quantities, while smaller plants 

 are located throughout the rest of the limestone areas. The rail- 

 roads at the present time are largely using crushed stone in place 

 of gravel as ballast ; the agitation for good macadam roads has also 

 aided in the demand, while the barge canal and other concrete con- 

 structions have increased the use of concrete. In the barge canal 

 contracts, the quarries and crushers are located but temporarily 

 and part of the stone thus used is probably not included in our 

 tabulations. 



The total value of the production of crushed stone for the year 

 was $1,744,314, the largest yet recorded for any year. In 1908 the 

 value was $1,647,629. Erie county leads in production with a value 

 of $447,605 against $369,754 in 1908. It is followed in order by 

 the following counties, the production for 1908 being inclosed in 

 brackets; Dutchess $365,661 [$233,261]; Rockland, one large 

 producer; Genesee $123,784 [$122,310]; Onondaga $110,886 

 [$108,768]. 



Lime. Since the earliest days of the State, the manufacture of 

 lime has been carried on ; and many active or abandoned lime kilns 

 are found in all limestone sections. The prevailing economic con- 

 ditions, however, have tended toward a consolidation of the indus- 

 try and the manufacture is now mainly carried on from large well 

 equipped plants. Warren county alone produces 38 per cent of the 

 State's production, while the counties of Warren, Jefferson, Clin-
