The one new producer added to the list during the year was the 

 Knickerbocker Portland Cement Co., which began operation in 

 the summer at its plant near Greenport, Columbia county. The 

 mill is equipped with three rotary kilns, each 10 by 175 feet, and 

 under full headway is expected to turn out 3000 barrels a day. The 

 limestone quarries are situated on Becraft mountain close by and in 

 proximity to those of the New York-New England Company, in an 

 outlier of the Coeymans and Manlius formations. The clay is 

 obtained locally. 



CLAY 



The clay-working industries rank first in the value of annual out- 

 put among the mineral industries of the State. Their prominence 

 is chiefly due to the widely distributed deposits of common clays 

 suited for building brick, drain tile and materials of that class and 

 the very extensive local markets for such articles. As the whole 

 area of New York lies within the zone of Pleistocene glaciation, 

 residual clays are of rare occurrence and of little commercial 

 importance. 



Most of the clays that are utilized are modified glacial deposits.
