678 ANNUAL RKPOIIT OF THE Oflf. Doc. 



Valuations in Pennsylvania 



For reasons stated on the previous page, the New England schedule 

 has been followed in the case of mixed fertilizers and dissolved 

 bones. 



In the case of the dissolved rocks, the wholesale prices of raw 

 materials used in their manufacture and of the available phosphoric 

 acid itself, having shown no material change, the values used in the 

 Pennsylvania schedule for 1909 were continued for use during the 

 present year. 



In the case of ground bones, the commercial valuations for the fall 

 of 1909 were somewhat less, on the average, than the retail market 

 prices; moreover, the wholesale prices of bone showed some advance 

 during the fall and winter. The valuations and market prices have 

 therefore been brought into closer agreement by a slight increase of 

 the values assigned to bone nitrogen, the change at this point cor- 

 responding in direction to that for organic nitrogen in general. 



The entire schedule adopted for use in this State is presented in 

 the following table:

Potash in excess of that equivalent to the chlorin present, will be 

 valued as sulphate, and the remainder as muriate. 



In certain cases where specific claim is made by the manufacturer 

 that potash has been added as carbonate, potash in excess of that 

 equivalent to soluble chlorides and soluble sulphates will be valued as 

 carbonate. 



Nitrogen in mixed fertilizers will be valued as derived from the 

 best sources of organic nitrogen, unless clear evidence to the con- 

 trary is obtained. 



Phosphoric acid in mixed fertilizers is valued at bone phosphoric 

 acid prices, unless clearly found to be derived from rock phosphate. 



Bone is sifted into two grades of fineness: Fine, less than 1.50 inch 

 in diameter; coarse, over 1-50 inch in diameter.
