THE MINING AND QUARRY INDUSTRY ICH2 23 



The output of drain tile was contributed by nine counties, of 

 which Albany had the largest product. The value of the year's 

 manufacture amounted to $122,571 against $202,292 in 191 1. Re- 

 ports were received from 16 active plants, or the same number as 

 reported in the previous year. The value of the sewer pipe pro- 

 duced was $77,644 as compared with $138,258, all from Monroe 

 county. 



Fireproofing, including terra cotta lumber, hollow brick and 

 various other kinds of hollow clay ware used for fireproofing, was 

 made last year by six companies with plants situated among the 

 counties of Erie, Kings, Monroe, New York, Oneida and Rens- 

 selaer. The total value of the output was $230,833, as compared 

 with $229,627 in 191 1 when 7 companies were active. Local clays 

 are employed for these articles. 



Building tile, including roofing tile, vitrified floor tile, and terra 

 cotta tile, was reported from Allegany, Kings and Monroe counties 

 by 3 firms. The output had a value of $42,575, against $82,217 

 in 191 1. 



Architectural or ornamental terra cotta showed a large increase 

 last year, reaching a value of $1,139,291, as compared with $718,700 

 in 191 1, the largest that has ever been reported. Its manufacture 

 is carried on by 3 companies in Queens, Richmond and Steuben 

 counties. 



The miscellaneous clay materials accounted for a value of $13,828, 

 against $20,179 in the preceding year. 



POTTERY 



The manufacture of pottery has become one of the larger branches 

 of the clay-working industry, showing a steady gain of output dur- 

 ing the last several years until it now ranks second only to brick- 

 making in importance. The materials used are mostly brought 

 from outside sources as there are no deposits of white-burning 

 clays suitable for china or porcelain within the State. Feldspar, 

 quartz and stoneware clays, as well as an excellent grade of slip 

 clay, exist in large deposits, but except for slip clay, the local re- 

 sources are not utilized to any extent for pottery. The recent 

 growth of the home market seems to afford opportunity for develop- 

 ment of some of those resources, especially those of feldspar and 

 quartz. 



The products of New York potteries include porcelain and china 

 tableware which are made chiefly by the Onondaga Pottery Co.
