 siderable quantitywas sold to dry mixers who used it in preparing the 

 final product. The quantity of acid phosphate used by dry mixers in 

 1917 was 494,261 tons, leaving about 1,500,000 tons of acid phos- 

 phate sold for direct application- to the soil. The quantity of mixed 

 fertilizer produced was 4,443,000 tons in 1917 and 4,958,000 tons 

 during 1918. Certain quantities of bone, tankage, blood, fish scrap, 

 and cottonseed meal were sold in their original state; also some 

 nitrate of soda, but beginning with July, 1918, practically no nitrate 

 of soda was sold as such.
