an increase of about 30 per cent for the year, and the largest out- 

 put in the history of the industry. The demand for paving brick 

 has developed rapidly with the growing recognition that they are 

 one of the few materials which will withstand the hard usage of 

 modern street traffic. In the last few years particularly they have 

 come into general favor and are now being utilized for the rebuild- 

 ing of many highways throughout the State. In the year 1914 a 

 total of 49,374,169 paving brick were laid on State roads, or more 

 than the local production. Most of the output of the local yards 

 was shipped outside, less than one-fourth being used within the 

 State. The production of paving brick in the last decade is given 

 in the accompanying table.

 glazing. The output in 1914 had a value of $892,630, which as

 year, represented a decline of 10 per cent. The unsettled business
