DRAIN TILE 



The production of drain tile in New York State is carried on by 

 thirteen firms who operate on a small scale. The output barely suf- 

 fices to supply local markets. It is made mostly from soft plastic 

 clays by a stiff mud process under the same conditions as those de- 

 scribed for hollow brick and fireproofing. The output in 19 13 has 

 a value of $134,199. 



POTTERY 



Pottery stands second in the list of clay products in importance, 

 and the industry has shown a steady growth. The crude materials 

 for the finer grades are mainly imported from abroad or from other 

 States, although the red earthenware products contain local clays. 

 The following table gives the values of the different poitery mate- 

 rials as reported by the individual producers. The value assigned 

 in the porcelain electric supplies includes also the value of the metal 

 fixtures which amounts in the average to about 30 per cent of the 

 whole.

THE MANUFACTURE OF PAVING BRICK IN NEW YORK STATE 



With the activity in State, county and municipal road construction, 

 there has developed an insistent demand for a paving material that 

 will stand the hard usage of modern traffic. Various methods of 

 construction have been tried on the highways, and it may be said 

 that the test of experience is favorable to the use of vitrified paving 

 brick whenever the traffic is sufficient to warrant the high first cost 

 of the material. When properly laid, paving brick give good satis- 

 faction as to durability, appearance and low repair cost. Their use 

 in this country does not date back much further than 30 or 40 years, 

 but they have steadily gained in popularity and no doubt are des- 

 tined to play a much more important part in future road construc- 

 tion than in the past.
