CLAY 



BY ROBERT W. JONES 



Due to the decrease in building construction during the year 

 1914 the production of clay products, along with other building 

 materials, fell off considerably from that of the preceding season. 

 In four of the principal cities of the State that depend largely 

 upon local materials for building purposes, the falling off in con- 

 struction during 1914 as compared with 191 3 amounted to an 

 average of 22.1 per cent. In New York City alone, building con- 

 struction fell off 16.8 per cent. 



The following table gives the production of clay materials in the 

 State during the last three years :

One hundred ninety companies or individuals were active during 

 the year as compared with 204 during the season of 191 3. One 

 hundred thirty-three reported a production of common soft-mud 

 building and 13 a production of wire-cut building brick, or all to- 

 gether 145 as compared with 159 for the preceding year. The 

 aggregate number of common building brick manufactured during 

 the season amounted to 932,759,000 as compared with 1,090,506,000 

 for 1913; their value was $4,597,856 against $5,938,922 for 1913. 

 Of the number of common building brick produced, 55,071,000 

 were made by the stiff-mud, wire-cut process with a value of $365,- 

 159 as compared with a value of $424,894 during 1913. All clay 

 products, with the exception of vitrified paving brick, fell off in 

 value. Paving brick made an increase of 15.1 per cent in value and 

 23 per cent in quantity over 191 3.
