acid used is relatively small and the need for its separate valuatiou 

 not apparent; in other States it predominates to the almost entire 

 exclusion of bone i)hosphoric acid, so that no distinct valuation for 

 the latter is required; but in Pennsylvania both occupy important 

 positions upon the market and each requires its own set of values. 

 Despite the slightly upward tendency of the acid phosjdiate market, 

 it is thought needless to change the valuations of these constituents 

 at this time, because the average valuations have, under the exist- 

 ing schedule, considerably exceeded the actual selling prices. 



For similar reasons, nitrogen and phosphoric acid in ground bone 

 are valued at lower rates in Pennsylvania than in New England. 

 Owing to the fact that the bone valuations of the past year fell dis- 

 tinctly below the selling prices, a slight increase in the valuations 

 of these goods has been made. Tankage is scheduled with bone, 

 though costing less, because it is little sold at retail. 



The schedule for 1!)02, as a v^hole, is as follows:

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

 valued as sulfate, and the remainder as muriate. 



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.
