BRICK YARDS

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 

 generally be used for the manufacture of hollow brick. The 

 same sort of machine is used in their manufacture as is used for 

 drain-tile, a different shape of die being of course needed. The 

 brick are made in various sizes and of rectangular cross section. 

 They are manufactured by the following firms : 



Wyandance Brick and Terra Cotta Co., Wyandance, Long 

 Island, 



J. E. Mecusker & Son, Jamestown, 

 Adams Brick and Terra'Cotta Co., Buffalo, 

 Onondaga Vitrified Brick Co., Warners, 

 John Lyth & Sons, Angola. 



Terra cotta lumber differs from the above in having about fifty 

 per cent, sawdust added to the clay. This is burned out in the 

 kiln giving a porous product. It is used for partitions and nails 

 can be driven into it. Only two firms in New York are making 

 it, viz. The Onondaga Vitrified Co. and John Lyth & Sons. 



Stoneware — Clay 



Deposits of clay suitable for the manufacture of stoneware are 

 found on Staten Island and Long Island. Those of S. L are 

 located at Kreischerville. The L. I. ones are found at Elm Point 

 on Great Neck, Glen Cove and Little Neck near Northport. 

 They are shipped to Poughkeepsie, Rochester, Utica and Ellen- 

 ville in N. Y.; also at New Haven, Stamford, Norwalk and Hart- 

 ford, Conn ; Newark, N. J.; and Pittston, Pa. 



The Long Island clay is usually mixed with the Jersey clay in 

 proportion of one to three. These latter clays, if used alone for 

 the manufacture of stoneware, are apt to crack in burning, due 

 to the unequal shrinkage and warping, while the Long Island
