ANNUAL REPOP.T OF TllK 



OlY. Doc. 



The valaalioiis dining 11)01 lor the luore important classes of fer 

 tilizei's were cousiderably higher than the selling prices; the diller- 

 ence was more marked in the fall than in the spring. As usual, the 

 selling prices of rock-and-potash maintain a disproportionately 

 high level. 



The general tendencies of the wholesale market may be judged 

 from the following comparative statement, obtained from the weekly 

 Imports of the Oll^ Faint and Drug Reporter^ of New York City, show 

 ing the average wholesale prices of fertilizer raw materials from 

 xSeptcmber 1, 1900, to March 1, IDUl, and from September 1, 1901, to 

 March 1, 1902.

In ammoniates, such as dried blood or concentrated tankage, the 

 unit is of ammonia, of which 82.35 per cent, is nitrogen; in acid 

 phosphates, the unit is of phosphoric acid (phosphorus pentoxid). 



The nitrogenous materials and animal sources of phosphoric acid 

 show the following changes from last year's prices. Sulfate of 

 ammonia has advanced slightly, while in the case of nitrate of soda 

 and fish guano there has been a distinct advance over last year's 

 figures. Concentrated tankage remains practically the same. Dried 

 blood and refuse bone-black have fallen off slightly; rough bone and 

 bone meal show a marked decrease. The following data are from 

 the monthly reports of Thos. J. White & Co., fertilizer brokers, Balti 

 more. Md.. giving wholesale quotations u]!on ammoniates.
