FERTILIZER TRADE VALUES. 



No schedule of trade values of fertilizing materials has been attempted, as 

 it was recognized that the excessive and widely fluctuating prices which have 

 prevailed would make such a list of little value. In order to make a record 

 of the prices charged for certain of the better known crude stock fertilizing 

 materials, the following table has been prepared : —

GENERAL INFORMATION CONCERNING REGISTERED RAW 

 PRODUCTS AND CHEMICALS. 



Ground Bone. — Thirty-nine samples have been inspected during the 

 season, necessitating 23 analyses. Ground bone has averaged 3.10 per cent, 

 of nitrogen and 24,65 per cent, of phosphoric acid. The average retail cash 

 price per ton has been $48.84. On the whole the guarantees on ground bone 

 have been well maintained, none of the brands showing a commercial shortage. 



Ground Tankage. — Seventeen samples of tankage have been inspected, 

 necessitating 14 analyses. No -deficiencies were found in nitrogen. Three 

 brands showed rather serious deficiencies in phosphoric acid. These de- 

 ficiencies, however, were more than made up by an over-run in nitrogen, so 

 that no commercial shortage resulted. The average total nitrogen found was 

 5.90 per cent. The average phosphoric acid found was 13.22 per cent. The 

 average retail cash price has been $63.40 per ton. Assuming that the pound 

 of phosphoric acid in tankage is worth 5 cents, the cost of a pound of nitrogen 

 from this source would have been 42.5 cents. 



Dry Ground Fish. — Sixteen samples of fish were inspected, necessitat- 

 ing 16 analyses. Three samples were found deficient in nitrogen and three in
