A SURVEY OF THE FERTILIZER INDUSTRY. 
17 
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 
ereater 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.
