ANNUAL REPORT OF THE 



Off. Doc. 



Giving attention first to the nitrogenous materials and animal 

 sources of phosphoric acid: These figures show a decrease in the 

 prices of ammonium sulfate and concentrated tankage during the 

 season of 1900-1, as compared with that of 1899-1900; those of 

 dried blood and fish guano have, on the other hand, distinctly ad- 

 vanced; those of nitrate of soda, rough bone and refuse bone-black 

 remaining practically stationary, though quotations for bone meal 

 are much reduced. 



The following data are taken from the monthly reports of Thomas 

 J. White & Co., fertilizer brokers of Baltimore, Md., giving whole-
