Upon a careful consideration of the changes and tendencies of the 

 wholesale prices of fertilizer ingredients and of the discrepancies 

 occurring since the adoption of the 1D02 schedule of valuation, it 

 has been decided that the schedule for use during 1903 should be the 

 same as that adopted for the use of New Jersey and New England 

 except at two points. 



For reasons fully discus'sed in earlier bulletins, it is needful to in- 

 clude in the Pennsylvania schedule of valuations, a distinct set of 

 values for i)hosphoric acid derived- from rock as contrasted with 

 that derived from animal materials. Keference to the tables, given 

 on an earlier page, showing the wholesale cost of a pound of phos- 

 phoric acid, will make it plain that when it comes from phosphate 

 rock, it costs the fertilizer maker about one-half of a cent a^t the 

 mines, on the Atlantic' seaboard; when from refuse bone-black, de- 

 livered at New York, 3.2 cents; when from tankage, about 1.1 cents; 

 and from bone 1.85 cents. 



There is nothing to indicate that, after acidulation, the available 

 phosphoric acid from bone is at all better for the crop than that 

 from a good rock lime phosphate. But so long as the consumer is 

 persuaded that bone phosphoric acid is worth more for his crop than 

 :.»n equal weight of rock phosphoric acid, just so long will the manu- 

 facturer of fertilizers be able to command a higher price for those 

 fertilizers reputed to derive their phosphoric acid from bone, and
