THE MINING AND QUARRY INDUSTRY I9II 



91 



The production of trap in 191 1 amounted in value to $899,414, a 

 small decrease from the total of $909,006 reported in the preceding 

 year, Alost of the output was employed for road metal and the 

 quantity thus used was 850,322 cubic yards valued at $696,367. 

 Crushed stone for other purposes chiefly concrete and railroad 

 ballast amounted to 267,930 cubic yards valued at $199,797. The 

 building stone had a value of $3250. Altogether there were 7 firms 

 represented in the industry, of which 6 operated quarries in Rock- 

 land county, and i the quarry at Greenfield, Saratoga county. The 

 Manhattan Traprock Co. of Nyack discontinued operations during 

 the year having disposed of its quarry property to the Palisades 

 Park Commission. 



The future of the trap industry in the PaHsades region is involved 

 with the plans for the creation of the park which has received legis- 

 lative approval in both New York and New Jersey. It is possible 

 that all quarrying operations may eventually be brought to an end. 

 Thus far the only company that has withdrawn from business is the 

 one mentioned, which worked quarries on Hook mountain, north of 

 Nyack.

TALC 



The talc mines in the Gouverneur district were quite active last 

 year, though their output was somewhat curtailed by the im]:>air- 

 ment of mill capacity incident to the long period of dry weather in 

 the late summer and fall, a condition that has" been repeated during 

 each of the last three seasons. The production amounted to about 

 65,000 short tons, all shipped in ground form and mainly, as here- 

 tofore, for use io paper rnanufacture. Prices .averaged nearly the
