the product of building stone reached a value of $245,655. Erie 

 county contributed a value of $77,689 to the total last year. The 

 industry in Schoharie and Herkimer counties, once quite important,

Furnace flux. The value of the limestone used in furnaces for 

 flux is second only to that of crushed stone. The principal quar- 

 ries of this material are in the Onondaga limestone of Erie and 

 Genesee counties and the Clinton limestone of Niagara county. 

 They supply the iron furnaces at Buffalo and vicinity. Some flux 

 is obtained in the Gouverneur marble region for use in the furnaces 

 at Charlotte. The furnaces in the Lake Champlain section derive 

 their flux from quarries in Clinton and Essex counties. 



The production of flux in 191 1 was valued at $454,80x3 repre- 

 senting a total of 792,248 tons. The shipments were smaller than 

 in the preceding year, owing to the dull conditions in the iron 

 market. Erie county contributed the largest value, $268,082, and 

 Niagara county ranked second with $141,824.
