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

 The prices for potash are taken from the schedule of the syndicate, and those of the remainder 

 from the Oil, Paint tnd Drug Reporter. 



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 phosphoric acid 

 contained in this material. As compared with tankage, the gen- 

 eral 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. 



In former years the value assigned to the nitrogen has been the 

 same as that quoted on crushed tankage c. a. f. Baltimore. Last 

 year quotations for crushed tankage not being available the value 

 for nitrogen was based upon quotations or ground tankage 11 per 

 cent, ammonia, 15 per cent, bone phosphate, f. o. b. Chicago. In 

 the present instance quotations for both crushed tankage and 

 ground tankage being lacking the value for nitrogen is based upon 

 quotations for concentrated tankage. 



For the two previous years, quotations on ground tankage have 

 been about 5 per cent, in advance of those on concentrated tank- 

 age. As indicated last year, quotations on crushed tankage were 

 on an average 12.67 per cent, in advance of these on ground tank- 

 age. Increasing the price of concentrated tankage by these per- 

 centages we have |2.788 per unit of ammonia as the value assigned 

 to the nitrogen in bone. 



This is equivalent to |3.38 per unit of nitrogen. 



The average composition of the ground bone and bone meal 

 samples analj-zed last fall in Pennsylvania was: Phosphoric acid, 

 22.09 per cent.; nitrogen, 3.10 per cent. 



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

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

 in a measure, to neiitra,lise eacli otijer. Asmming for the rough
