Statistics of Quarries. 



According to the statistical tables of quarries and their production, 

 in Volume X, pp. 46-49, tenth census of the United States, 1880, 

 New York had 55 marble and limestone ; 181 sandstone ; 3 crystalline 

 siliceous rock : and 12 slate quarries, which did a business, each of 

 over $1,000, during the year that the census was taken. There were 

 3,302 laborers employed in these quarries and the value of the 

 product was $1,261,495. 



The survey for this report shows that in 1887 the number of 

 working quarries was 342 ; and distributed as follows : 



1. Granite and gneiss 11 quarries. 



2. Marble 7 quarries. 



3. Sandstone _ 235* quarries. 



4. Limestone 73 quarries. 



5. Slate _ _ 16 quarries. 



342 



The total number of laborers employed, including quarrymen and 

 stone-cutters at quarries, was5,400,f an increase of one-third over the 

 number reported by the United States census. 



The value of the equipment or plant is estimated to be not less 

 than $1,600,000. It represents the machinery, tools and sheds 

 necessary for quarry work, and excludes mills for cutting and dress- 

 ing the stone. 



The value of the product (estimated at) $3,500,000$ 



The value in 1880 (United States census) $1,261,495 



*Including 144 quarries in the Hudson River blue-stone belt, of territory, as 

 reported in the United States census for 1880. 



f The number of men employed in the quarries and in the quarry districts is from 

 individual statements of owners or managers in great part ; a few localities are 

 estimated ; and the Hudson River blue-stone district estimate ,of 2,000 men, is from 

 Wm. B. Fitch, of Kingston, Ulster county. 



| The total value is made up of statements for the several, larger quarry districts, 

 obtained from managers well acquainted with the extent of this industry, sup- 

 plemented by estimates made in the office, and based on the comparative number 

 of men employed.
