THE MINING AND QUARRY INDUSTRY I9II 6^ 



mately 2,900,000 cubic yards and of gravel 1,013,470 cubic yards, 

 as compared with 3,838,976 cubic 3^ards of sand and 1,037,026 cubic 

 yards of gravel produced in 1910. Nassau county from which 

 much of the sand used in building operations in New York is ob- 

 tained, contributed alone a total of 1,874,837 cubic yards of sand 

 and 659,106 cubic yards of gravel last year. 



SAND-LIME BRICK 



The manufacture of sand-lime brick last year was somewhat 

 larger than usual. Five companies reported as active and con- 

 tributed a total of 15,178,000 bricks with a value of $92,064. This 

 was but little short of the record production which was reported in 

 1907 and which amounted to 16,610,000 valued at $109,677. The 

 outturn in 19 10 was 14,053,000 with a value of $82,619. The sell- 

 ing price of the brick, fixed at the yard, averaged $6.05 a thousand 

 last year, against $5.88 a thousand in 1910. 



The following were the active plants : Composite Brick Co., 

 Rochester; Dyett Sand-Lime Brick Co., Port Jefferson; Buffalo 

 Sandstone Brick Co., Buft'alo; Paragon Plaster Co., Syracuse; 

 Granite Brick Co., Glens Falls. 



The Grant Brick Co. of Brooklyn and the Sandstone Brick Co. 

 of Schenectady reported as active in 19 10 but did not manufacture 

 last year. 



STONE 



The quarrying of stone and its preparation for the varied re- 

 quirements of building, engineering construction, etc., hold a 

 prominent place in the industrial activities of the State, and the 

 value of the annual contribution ranks second only to that of clay 

 among mineral materials. No other mineral industry includes so 

 many individual enterprises or is so widely represented in the 

 different sections. The resources are abundant and varied, com- 

 prehending all the principal varieties known to the trade. The 

 greater number of quarries, however, are opened in the limestones 

 and sandstones and supply material chiefly for engineering work, 

 highway improvement and such purposes which do not entail any 

 considerable amount of elaboration previous to shipment. In the 

 development of the building, monumental and ornamental branches 

 the local industry has not attained the relative importance that it 

 deserves by reason of the natural weaUh of materials adai)ted to 

 those uses and the advantages for marketing; herein lies, it would 

 appear, the principal field for future enterprise.
