THE MINING AND QUARRY INDUSTRY I9I4 55 



workings are in the vicinity of New York, Buffalo and Rochester. 

 New York derives its principal supply from the beach sands on the 

 north shore of Long Island, mainly from Nassau county. They 

 are dredged from shallow water and conveyed to market in barges. 

 They are among the best sands of their type, consisting of nearly 

 pure quartz sand, well sorted and fairly coarse. Buffalo is supplied 

 from the beach sands of Lake Erie. Glacial sands, modified by 

 stream action, are the sources of supply in Albany and Rochester 

 and many of the interior towns. 



The output of building sand in 1914 was returned as 3,710,796 

 cubic yards worth $1,151,521, about the same as was reported in 

 the two previous years. The output, however, included some filter 

 sand which previously was listed under another head. 



Molding sand. The production of molding sand was 310,727 

 short tons valued at $310,727, showing a large decrease for the year. 

 The falling off was the result of the depression in the metal trades 

 which curtailed the market. This grade of sand is produced in a 

 single district which includes the section along the Hudson river 

 from Saratoga and Washington counties on the north to Kingston, 

 Ulster county. The sand is a deposit formed in the glacial Lake 

 Albany, that has been sorted by wind action and modified by 

 weathering influences. The main production comes from the ter- 

 raced lands just north and south of Albany. The industry is 

 represented by a relatively few companies and individuals who 

 maintain continuous operations from year to year. The sand is 

 remarkable for its fine, even grain. 



SAND-LIME BRICK 



The manufacture of sand-lime brick was carried on last year by 

 three plants, one less than in 1913. The companies represented 

 were the Paragon Plaster Co. of Syracuse, the Buffalo Composite 

 Brick Co. of Buffalo, and the Rochester Composite Brick Co. of 

 Rochester, all of which have been in the business for several years. 

 The Glens Falls Granite Brick Co., the first to erect a plant in the 

 State for commercial production, did not operate during the past 

 season. 



The production for the year amounted to 17,696,000, valued ait 

 $111,326, against 22,225,000, valued at $143,345 in [913. The 

 average selling price was $6.29 a thousand as compared with $6.40 

 in the preceding year.
