The organic nitrogen in superphosphates, special manures and 

 mixed fertilizers of a high grade is usually valued at the highest 

 figures laid down in the trade values of fertilizing ingredients in raw 

 materials, namely, 18i cents per pound; it being assumed that the 

 organic nitrogen is derived from the best sources, viz., animal

 from leather, shoddy, hair, or any low-priced, inferior form of vege-
