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

 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, except 

 when sold in original packages. 



For mixing, an allowance of fl.OO per ton on complete fertilizers 

 and rock-and-potash goods. 



For agents' commission, an allowance of 20 per cent, is added to the 

 cash values of the goods ready for shipment. 



The mean quotation on freight from New Yoak, Philadelphia and 

 Baltimore to Harrisburg, in January, 1897, was |1.68 per ton, in lots

FERTILIZER ANALYSES, JANUARY 1 TO AUGUST 1, 1902. 



Since January 1, 1902, there have been received from authorized 

 sampling agents, eight hundred and thirty-eight (838) fertilizer sam- 

 ples, of which four hundred and fifty (450) were subjected to analysis, 

 the remainder being rejected either because they represented brands 

 analyzed last season, or because they were regarded as not certainly 

 representative of the brand whose name they bore. When two or 

 more samples representing the same brand were received, equal por-

The samples group themselves as follows: 289 complete fertilizers,

 furnishing phosphoric acid and nitrogen; 66 rock-and-potash fer- 

 tilizers, furnishing phosphoric acid and potash; 59 acidulated rock 

 phosphates, furnishing phosphoric acid only; 29 ground bones, fur-

 which group includes potash salts, nitrate of soda and other sub-
