eight firms, one each in Albany, Erie, Kings, Monroe, New York, 

 Oneida, Onondaga, and Rensselaer counties. The value of the out- 

 put was $256,820 as compared with $166,025 in the preceding year 

 when six firms reported as active. The use of clay fireproofing is 

 growing very rapidly, and with the extensive markets to be found 

 in the State and bordering territory, the local industry should de- 

 velop to large proportions. Clays suitable for fireproofing are found 

 in various sections. 



Building tile, inclusive of roofing tile, vitrified floor tile and terra 

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

 Oneida counties, by a total of six firms. The output was valued at 

 $65,190 against $54,397 in 1909. This is another department of 

 clay-working which deserves greater attention than it has received 

 in the past. 



Architectural or ornamental terra cotta showed a good gain, with 

 a reported value of $1,062,017 against $962,497 in 1909. Its manu- 

 facture is carried on by three firms in Queens, Richmond and 

 Steuben counties. The Staten island Cretaceous clays are used in 

 part for this product. 



The miscellaneous clay materials accounted for a value of $134,- 

 752 against $101,497 in 1909.

POTTERY 



New York State is deficient in clays suitable for the finer grades 

 of pottery such as china and porcelain ware. The clay beds of 

 Long island, Staten island and Onondaga county have supplied 

 some stoneware clays, and slip clay of excellent quality is obtained 

 at Albany. Common earthenware clays also are abundant. There 

 are no commercial deposits of kaolin, so far as known, and the en- 

 tire requirements of this material are met by purchases from south- 

 ern mines or by importations from abroad. 



Notwithstanding the limitations of resources, the pottery indus- 

 try has shown a fairly steady growth. The output last year was 

 valued at $2,136,518 and was the largest that has ever been recorded. 

 The gain over the preceding year exceeded $300,000. The number 

 of potteries that contributed to the total was twenty-two, of which 

 all but one reported their production. Porcelain and semiporcelain 

 wares constituted the largest items in the total, with a value of 

 $1,027,249. Electric and sanitary wares, which are classed together 

 so as to conceal the individual figures, contributed $991,131 to the 

 total. The value of the electric supplies does not include the metal
