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 1901 schedule of valuation, it 

 has been decided that the schedule for use during 1902 should be the 

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

 except at two points. 



For reasons fully discussed in 1897, it is needful to include in 

 the Pennsylvania schedule of valuations, a distinct set of values for 

 phosphoric 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 phosphoric acid, will 

 make it plain that when it comes from phosphate rock, it costs the 

 fertilizer maker about one-half to three-fourths of a cent at the 

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

 livered at New York, 3.4 cents; when from tankage, about 1.1 cents; 

 and from bone 2.69 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 per- 

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

 an 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 just 

 so long will he, in turn, be obliged to pay more for it on the whole- 

 sale market. Now, in some States, the volume of rock phosphoric
