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 1911. 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 1911 when 7 companies were active. Local clays 
are employed for these articles.

cotta tile, was reported from Allegany, Kings and Monroe counties 
by 3 firms. The output had a value of $42,575, against $82,217

Architectural or ornamental terra cotta showed a large increase 
last year, reaching a value of $1,139,291, as compared with $718,700 
in 1911, 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.
