valued at $31,500 in the previous year. The remainder of the out- 

 put came from Erie county. In all there were nine plants active, 

 or three less than in 1905. The Buffalo Cement Co., of Buffalo 

 and the Potter-Brown Cement Works at Manlius, Onondaga co.,. 

 were inoperative and will probably not resume the manufacture of 

 natural rock cement. The Akron Cement Works also suspended 

 operations.

CLAY 



The manufacture of brick and other clay products is the most 

 important branch of the mineral industry in New York. Clay 

 deposits suitable for making the common wares are distributed 

 throughout every section in practically inexhaustible quantities. The 

 rapidly growing market for these products has led to the establish- 

 ment of numerous manufacturing plants in recent years, so that 

 now there is scarcely an industrial center of any size in which they 

 are not produced. This is particularly true with regard to the 

 manufacture of building materials, which are being employed more 

 and more widely as an element in permanent construction. Owing 

 to their cheapness, durability and the convenience with which they 

 can be adapted to meet the varied architectural requirements, the 

 use of these materials will doubtless continue to expand for a long 

 time to come.
