THE CLAY INDUSTRIES 



Clay-working plants are widely distributed over the State and 

 their products include a large variety of wares. Brickmaking is 

 the largest branch, both in regard to the number of enterprises and 

 the value of their aggregate annual output. Common building 

 brick constitutes the main item of production, but front and orna- 

 mental brick and vitrified paving brick are manufactured in smaller 

 quantities. Next to this branch in importance is the pottery 

 industry which accounts for a considerable proportion of the annual 

 total, and has shown such progress in the last few years that it 

 promises to become the leading department in regard to value of 

 the product although restricted to a few centers and dependent 

 largely upon outside supplies of rav/ materials. 



The accompanying table exhibits the figures of production for 

 the leading branches, as well as the aggregate output for the entire 

 industry during the period 1904-19 18. The figures for the last 

 three years were compiled by this office in cooperation with the 

 United States Geological Sui'vey; for the earlier years they were 

 collected by this office independently by canvass of the whole trade.
