manufacturers in the Hudson valley, who sell in the New York 
market. The average prices in that important center were con- 
siderably above those reported for 1910 and 19gIT. 
Among the other branches of the clay-working industry, those 
of pottery and terra cotta also showed good increases, the produc- 
tion of pottery being much the largest ever reputed. The remain- 
ing products, inclusive of paving brick, fire brick, drain tile, sewer 
pipe and fireproofing were manufactured on a reduced scale. 
The actual value of the production of clay materials of all kinds 
in 1912 was $11,947,497 as compared with a value of $9,751,659 
in I9IZ and $11,518,982 in 1910. The gain for the year was 
$2,195,838 or about 23 per cent. The largest value recorded for 
any year was in 1900 when it amounted to about $14,000,000.
