Ammonia 2.99 % X 20=59.8 lb in ton, @ 19c= $11.36 



Available phosphoric acid 8.02 % X 20=160.4 lb @ 8c= 12.83 



Insoluble phosphoric acid 2.24 % X 20= 44.8 lb @ 2c= .90 



Potash soluble in water 1.68 % X 20= 33.6 lb @ 6c= 2.02 



Market value, equals $27. LI 



The whole value of a ton of superphosphate seems to be determined by 

 a little less than 300 pounds of the material. The remaining 1,700 pounds 

 may be considered as made up as follows: 



The 205 pounds of phosphoric acid would require 447^ pounds of 

 bone phosphate, or tricalcic phosphate, and this converted into 

 superphosphate and sulphate of lime would make 782-J- pouuds 



of lime salts 782.5 



The nitrogen would require 374 pounds albumenoids 374.0 



The potash as sulphate 66.5 



Bones contain 25 7c carbonate, etc., of lime, as sulphate 350.0 



Moisture and excess of sulphuric acid 195.0 



Total__, • 1,768.0 



Dirt, charcoal, etc 232.0
