VALUATIONS OP FERTILIZERS. 



The market value of a commercial fertilizer is governed by the 

 cost of the several ingredients which compose it, adding freight, 

 cost of bagging, mixing and agents' commission. The value, there- 

 fore, is subject to the variations in the market price of nitrogen, 

 phosphoric acid and potash in their various forms. Each year, there- 

 fore, the list of prices used by the Department for the computation 

 of values, is revised and published for the benefit of purchasers. The 

 schedule of values for fertilizer ingredients for 1902 is as folllows:

In fine bone, tankage and fish, 3 



In coarse bone and tankage 2IV4 



In cotton seed meal, castor pomace and wood ashes 4 



Potash : 



In high-grade sulfate or in forms free from muriate, 5 



As muriate Wz 



- Potash in excess of that equivalent to the chlorin present, will be 

 valued as sulfate, and the remainder as muriate. 



Nitrogen in mixed fertilizers will be valued as derived from the 

 best sources of organic nitrogen, unless clear evidence to the con- 

 trary is obtained. 



Phosphoric acid in mixed fertilizers is valued at bone phosphoric 

 acid prices, unless clearly found to be derived from rock phosphate. 



Bone is sifted into two grades of fineness: Fine, less than 1-50 inch 

 in diameter; coarse, over 1-50 inch in diameter. 



The result obtained by the use of this schedule does not cover the 

 items of mixing, bagging, freight and agents' commission. To cover 

 these, allowances are made as follows: 



For freight, an allowance of |2.00 per ton on all fertilizers. 



For bagging, an allowance of .f 1.00 per ton on all fertilizers, except 

 when sold in original packages.
