670 ANNUAL. REPORT OF THE Off. Doc. 



That is, these States adopted for lOUS the schedule used in 1907. 

 It should be understood that the station oflQcials are influenced in 

 fixing- the schedule not only by wholesale quotations such as those 

 presented on the foregoing pages, but also by a large volume of 

 data from trustworthy sources representing current retail quota- 

 tions. 



The schedule thus adopted reflects very well the wholesale market 

 quotations for the principal nitrogenous, phosphatic and potasic 

 materials going to make up the bulk of the commercial fertilizers 

 used in the states joining in the adoption of the schedule just stated. 



The schedule is also adopted for use in Pennsylvania for the year 

 1908, except as it affects the valuations of dissolved rock and 

 ground bone, the New York wholesale prices for which do not corre- 

 spond closely with Pennsylvania retail values. 



Respecting dissolved rock: The computed average commercial 

 valuations for both the spring and the fall sales were practically 

 identical with the average selling prices for this class of goods, the 

 schedule pound values for water-soluble and citrate-soluble phos- 

 phoric acid having been increased in 1907 by one-half cent, although 

 the New York quotations for available phosphoric acid in acid phos- 

 phate had not been raised in spite of marked advances in the cost 

 of the corresponding raw materials and of labor. In view of this 

 close agreement between valuation under the 1907 schedule and 

 the selling prices in the fall of that year, and in view of current 

 retail quotations, it has seemed best to retain during 1908 the pound 

 values scheduled in 1907 for phosphoric acid derived from rock, as 

 they are stated in the schedule given below. 



Respecting bone: — The average commercial A-aluation in the 

 spring of 1907 was |1.91 below the selling price per ton, but in the 

 fall, slightly above the selling price. The schedule values for bone 

 nitrogen had been somewhat increased, reflecting the general ad- 

 vance of nitrogenous materials, although the wholesale quotation for 

 rough bone had shown no change. In view of the fact that the 

 commercial valuation in the fall of 1907 correspond closely with the 

 selling prices, that the wholesale quotations for bone meal from 

 September, 1907, to March, 1908, dropped nine per cent., in the face 

 of a nine per cent, increase in the quoted prices for rough bone, it 

 has seemed unnecessary to make any change in the basis of valua- 

 tion for ground bone adopted in 1907, in this respect following the 

 action of the New England Stations.
