IV. — Flour of Bone for Fertilizers. 



(Mr. Benjamin Randall, South Boston.) 



Moisture and organic matter, 44.10 



Ash-constituents, 55.90 



Phosphoric acid in ash (total), 21.94 



" " soluble in citrate of ammonia, .... 6.34 



Nitrogen in animal matter, 3.58 



This sample was sent on by the manufacturer ; it deserves 

 notice on account of its fine mechanical condition and its com- 

 parative large percentage of soluble phosphoric acid. 



V.— Steamed Bones and Meat. 



(Mr. James Byrnes of Springfield, Mass.) 



Moisture and organic matter, 48.38 



Ash-constituents, . . 51.62 



Phosphoric acid in ash, 21.90 



Nitrogen in animal matter, 3.86 



Moisture (at 100°-1 10° C), 6.05 



This material was collected from a large stock at the factory ; 

 its general physical conditions were very good and its com- 

 position equal to the guaranty stated. 



The phosphoric acid in the bones, steamed and raw genuine, 

 is valued according to the mechanical condition of the bones ; 

 the same rule applies with equal force to the valuation of the 

 nitrogen in their nitrogenous matter. 



Per pound. 



Phosphoric acid of bones soluble in citrate of ammonia, 7 @ 8 cents. 



Phosphoric acid in finely granulated steamed bones, . 6 cents. 

 Phosphoric acid in coarsely ground bones, 5 " 



Nitrogen in finely granulated bones, 18 " 



Nitrogen in coarsely ground bones, 15 " 



Farmers do well to take these points into consideration 

 when buying their ground bones for fertilizing purposes. 

 The composition of the above six samples differs not more 

 than different lots of bones will be found to do. All, with 

 but one or two exceptions most likely, have been rendered 

 before being ground. Fine ground steamed bones have sold 

 in small quantities at $40 per ton of 2,000 pounds. Unadul- 

 terated ground bones are furnished at that price, a valuable
