A SURVEY OF THE FERTILIZER INDUSTRY.

therefore, the stocks on June 30 are at a low ebb. One of the items 

 worth noting in connection with the stocks is the increase in the stock 

 of potash in 1918 as compared with 1917. The production of potash 

 in this country had increased decidedly and the stocks on hand were 

 much larger than a year earlier. The stocks of sodium nitrate were 

 greater in January, 1918, than in January, 1917, but the stocks of 

 ammonium sulphate had declined and the stock of cyanamid was very 

 low owing to the fact that cyanamid was practically all requisitioned 

 by the Ordnance Department. The supply of tankage and of dried 

 blood was lower in 1918 than in 1917, owing to the great demand for 

 these materials as feed. On the other hand, cottonseed meal was 

 represented by a larger stock in 1918 than in 1917.
