put of 958,763 cubic yards valued at $607,107. The other leading 

 counties were Dutchess, Rockland, Ulster, Onondaga, Genesee and 

 Albany. 



Lime. The value of lime made for market last year was $452,002 

 as compared with $400,396 in 191 1. In quantity, it amounted to 

 93,176 short tons. In addition there was a large output made in 

 connection with chemical manufactures, such as alkali, carbide etc., 

 which, as it was not sold as such, has been included under " other 

 uses." The principal quarries for lime manufacture are in Warren, 

 Clinton, Washington, Lewis and Jefferson counties. 



Building stone. The limestones found in the State have a lim- 

 ited 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 seems to be due to the fact that the 

 limestones are prevailingly of grayish color in medium to dark tints, 

 whereas the present demand is for white or very light gray stone 

 such as the Bedford stone. 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 total product of building stone, according to the returns 

 for 1912, had a value of $108,581. This was a little larger than 

 the value for 191 1 which amounted to $99,049, but considerably 

 less than the totals reported in some of the earlier years. Erie 

 county as usual was first in this branch of the trade; its output was 

 valued at $67,912. Cayuga, Onondaga, Montgomery, Warren and 

 St Lawrence counties contributed smaller amounts. 



Furnace flux. The output of stone for use in blast furnaces, 

 foundry furnaces and other metallurgical operations has assumed 

 large proportions. For such purposes, a relatively pure material is 

 desired, though the presence of magnesia may not be detrimental 

 to some applications as in iron smelting. The principal quarries of 

 flux are in the Onondaga limestone of Erie and Genesee counties 

 and the Clinton limestones of Niagara county. Smaller amounts 

 of flux are obtained from the Precambric crystalline limestones in 

 St Lawrence and Essex counties, the Chazy limestone in Clinton 

 county, and other formations. 



The production of flux in 1912 was valued at $542,154, represent- 

 ing a total of 1,032,481 tons. The corresponding figures for the 

 preceding year were $454,800 and in quantity 792,248 tons. Niagara 

 county had the largest production, with Erie in second place.
