1 Two analyses made. 



' Three analyses made. 



5 Chemical analysis confirmed by a microscopical examination indicates the presence of the following 

 adulterants: ammonium sulfate to furnish .64 per cent nitrogen, acid phosphate, raw mineral phosphate, 

 and horn and hoof meal. In place of being a genuine ground bone it was a product made by substituting 

 other materials at a lower unit cost of nitrogen and phosphoric acid, yet ha\'ing about the same content of 

 plant food as is usually found in steamed bone meal. It is only fair to add that the firm registering the 

 material bought it for genuine ground bone. 



* Collected at Somerville. Commercial valuation $42.82. Commercial shortage S5.23 per ton.
