THE MINING AND QUARRY INDUSTRY 951 



The McCormick Red Slate Co., the Bonanza Slate Co., and the

 have opened quarries and will work them during the present year. 

 The Welsh Red Slate Co. of Poultney, Vt., which formerly operated 

 quarries at Hampton, has retired from business. 



STONE 



All of the principal building and ornamental stones are quarried 

 in New York and most of them on a large scale. In the following 

 pages a brief description is given of their occurrence throughout 

 the State, together with information relating to production and 

 developments during the past year. The slate and millstone 

 industries which might properly be included here have been treated 

 under separate headings owing to their somewhat special character. 



Production of stone 



The value of the quarry products for 1904 amounted to $5,124,251. 

 This sum covers the output of all varieties of stone excepting 

 slate and millstones and that portion of the limestone which was 

 used for the manufacture of hydraulic cement. It represents the 

 aggregate product of over 600 quarries. 



The value of the limestone production was $2,058,405. The 

 sandstone quarried amounted in value to $1,896,697, of which the 

 greater part was reported by companies engaged in the bluestone 

 trade. The output of trap rock, mostly from the Hudson river 

 Palisades, was valued at $468,496; marble at $478,771; and 

 granite at $221,882. Classified as to uses, crushed stone was the 

 most important item in the production. The value of this material 

 amounted to $1,557,974, representing approximately 2,224,000 

 cubic yards. Building stone accounted for $1,254,548, while 

 curb and flagstone were produced to the value of $908,280. The 

 monumental stone quarried was valued at $165,935. The value of 

 the stone quarried for purposes other than those given was 

 $1,237,514. 



As noted in the accompanying table, the totals for building 

 stone, crushed stone and curbstone do not include certain items 

 which should be classified under these heads, but the results are 

 not appreciably affected thereby.
