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 

 recent developments. The slate, marl 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 1905 amounted in the aggre- 

 gate to $6,107,147. The value of the limestone quarried was 

 $2,411,456. The sandstone was valued at $2,043,960, the greater 

 part reported by companies engaged in the bluestone trade. The 

 output of trap, mostly from the Hudson river Palisades, was valued 

 at $623,219. Marble accounted for a value of $774,557. The value 

 of the granite produced was $253,955. Classified as to uses, build- 

 ing stone was one of the leading items in the production with an 

 aggregate value of $1,488,009. It was exceeded only by the value 

 of crushed stone which aggregated $1,902,623. Curb and flagstones 

 amounted to the sum of $1,037,210, represented almost entirely by 

 bluestone. The monumental stone, principally marble, was valued 

 at $187,988. The value of the stone quarried for purposes other 

 than those given, including lime, furnace flux, paving blocks, 

 rubble etc. was $1,491,317. . 



A comparison of the above totals with the corresponding figures 

 for 1904 shows that there was a large expansion in the quarrying 

 industry last year which was shared by all branches. The aggregate 

 increase amounted to $937,206, or about 18 per cent. This was 

 distributed along the different varieties of stone as follows: lime- 

 stone, $307,361; sandstone, $147,263; marble, $295,786; granite, 

 $32,073 ; and trap $154723.
