designed to produce cement by a dry method. Under the 'new 

 management changes in methods of operation have been made and 

 the production will be by wet method. Several attempts have been 

 made on a small scale to produce cement with potash as a by- 

 product. It is understood that during the present year construction 

 work will be begun on a plant to be operated along this line. 



During 191 5 there was a decline in the output of natural cement 

 although on account of the portland cement market conditions the 

 price per barrel realized at the New York market was higher than 

 for 1914. The output amounted to 223,564 barrels with a value of 

 $134,138 as compared with 232,076 and a value of $115,117 for 

 1914. Nearly the entire output comes from the Rosendale region. 

 There were three active plants in the State.
