Flower Pots 



There is a deposit of mottled blue clay on Long Island between 

 Southold and Greenport, which is used for manufacturing flower 

 pots at the latter place. The clay at Oakland Valley on the land 

 of O. B. Wheeler has also been used for this purpose. {See 

 detailed account of brick yards.) 



Hollow Brick and Terra Cotta Lumber 



A clay that will make a good building brick or drain-tile can
