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

 valued as snljihate, 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. 



rhosphoric 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 fl.OO per ton on all fertilizers, ex-

FERTILIZER ANALYSES JANUARY 1, TO AUGUST 1, 1908. 



Since January 1, lf)()S, there have been received from authorized 

 sampling agents fifteen hundred and seventy-six fertilizer samples, 

 of which .six hundred and twenty-five were subjected to analysis. 

 Preference is given to those which have not been recently analyzed. 

 In cei-lain cases where two or more samples represenling the same 

 brand were received, equal portions from the several samples were 

 united, and the composite sample was subjected to analysis. 



The samples analyzed group themselves as follows: 452 complete 

 fertilizers, furnishing phosphoric acid, potash and nitrogen; 4 dis- 

 solved bones, furnishing phosphoric acid and nitrog(Mi; lOS rock-and- 

 potash fertilizers, furnishing phosphoric acid and potash; 33 acidu-
