THE MINING AND QUARRY INDUSTRY IQIO 



73 



The production of trap in 1910 amounted to 1,185,780 cubic 

 yards valued at $909,006, an increase of quantity but a decrease in 

 value as compared with the totals reported in the previous year. 

 Of the production a little less than 90 per cent was sold for road 

 metal and the remainder for concrete work and ballast. Eight 

 firms were represented in the industry, seven of which operated 

 quarries in Rockland county, and one the quarry at Greenfield, 

 Saratoga county. The Ramapo Trap Rock Co. of Suffern, Rockland 

 county, was a new producer. 



During the past year plans were formulated for the establish- 

 ment of a State park which will include the Palisades from the 

 New Jersey state line north into Rockland county. By a legislative 

 enactment it is proposed to acquire by purchase or condemnation 

 the lands lying between the base and top of the Palisades and also 

 such unimproved lands on the top from the New Jersey state line 

 to Piermont creek in Rockland county, as are necessary to preserve 

 the scenic features from further injury. The execution of this plan 

 was placed in charge of the commissioners of the Palisades Inter- 

 state Park. The quarries of the Manhattan Trap Rock Co. have 

 already been acquired and it is reported that the others will be taken 

 over in the near future. In that event the trap industry which for 

 many years has supplied a large part of the crushed stone to the 

 lower Hudson region will be reduced to small proportions if not 

 definitely ended. •
