•The prices of phosphate rock are f. o. b. at the respective points of shipment, not New York. 

 The data for rock prices are taken from the reports of thg Eiujiiitcriii'i and Mining Journal; the 

 prices for potash from the schedule of the Syndicate; the rest from the Oil, Paint and Drug Re- 

 porter. 



The quotations for bone are given without specific reference to 

 (Quality, so that it is impossible from these data to fairly apportion 

 their several wholesale values to the nitrogen and the phosphoric 

 acid contained in this material. As compared with tankage, the 

 general tendency is to assign a higher commercial rating to the phos- 

 phoric acid in bone and to the nitrogen a rating not very different 

 from that given in tankage. 



The quotations of Thos. J. White & Co., show an average whole- 

 sale rate in Baltimore during September, 1900, to March, 1901, for 

 crushed tankage to have been 12.29 per unit of anmionia and $0.10 

 per unit of bone phosphate of lime; this is equivalent to |2.78 per 

 unit of nitrogen (13.94c per pound), and $0,218 per unit of phosphoric 

 acid (1.1c per pound). 



The average composition of the ground bone and bone meal sam- 

 ples analyzed in Pennsylvania, last Fall, was: 



Phosphoric acid, 22.52 per ecnt., nitrogen, 3.18 [)er cent. 



The prepared bone contains less fat and moisture, and often less 

 nitrogen than the ordinary "rough bone"; but these differences tend, 

 in a manner, to neutralize each other. 



Assuming for the rough bone quoted in the New York markets 

 the same composition as the bone meal sold in Pennsylvania, and 

 for the value of the nitrogen, $2.78 per unit, the values per pound of 

 the several constituentB would be:
