98 NEW YORK STATE MUSEUM 



of .Rochester. Mr J. J. Clearwater of Highland, N. Y., and 

 Messrs P. H. and J. Conlon of Newark, N. J., have kindly 

 furnished the records of a number of wells bored by them. In 

 the preparation of this report the following books and 

 periodicals have been consulted : The Clay Worker, the Brick- 

 maker, Brick, Tiles and Terra cotta by C. T. Davis, Engineering 

 News, Engineering Record, and the Encyclopedia Britannica. 



The increasing value of clay for the manufacture of brick, 

 tile, terra cotta, pottery, etc., and the ever growing demand for 

 these products have given rise to an industry which is rapidly 

 assuming vast proportions, and will in the near future become 

 one of the most extensive and important in the country. Scat- 

 tered over New York are extensive deposits of clay, many of 

 them capable of being used for the manufacture of terra cotta, 

 roofing tile and the coarser grades of pottery. To add to their 

 value the most extensive beds of clay are situated in close 

 proximity to the water ways and railroads which lead to the 

 principal cities of the state. The commoner kinds of clay pro- 

 ducts, such as building brick, are marketed within the state, but 

 the higher grades, such as terra cotta and roofing tile, have 

 found good markets outside of New York. 



The following table gives the receipts derived from the 

 various branches of the clay industry during the year of 1892: 



Building, front and paving brick $8 , 500 , 000 



Terra cotta 100,000 



Sewer pipe 260,000 



Fire brick* 50,000 



Stoneware clay 10 , 000 



$8,870,000 



As will be seen from the above statement bricks are the chief 

 source of income. That the other branches of the clay industry 

 are not further advanced is probably due in a large measure to 

 the fact that the clay deposits of the state have been so little 

 exploited or otherwise examined. Though many of the deposits 

 have been opened up and are still being worked, there are numer- 

 ous others scattered over the state which are still untouched. 



! *This does not include those manufactured In the state from clays obtained in other 

 states.
