The figures for 1900 exhibit an unusual difference between the 

 control valuations and Ihe actual selling prices in the case of in- 

 complete fertilizers; this is the more notable because of the sat- 

 isfactory agreement between valuation and selling price in the 

 case of the complete fertilizers. As usual, the rock and potash mix- 

 tures exhibit the same relative elevation of selling price to which 

 attention has been calhid in precedmg years. It is very probable 

 that the marluMi centralization in the organization of the retail 

 trade which the last year or two has witnessed nuiy account for this 

 stilTening of retail prices of the commonly uc^ed, incomplete fer- 

 tilizers. 



The general tendencies of the wholesale market may be judged 

 from the following comparative statement, obtained from the weekly 

 reports of the il^ Paint and Dmg Reporter, of New York city, show- 

 ing the average wholesale prices of fertilizer raw' materials from Sep- 

 tember 1, 1899, to March 1, 1900, and from September 1, 1900, to 

 March 1, 1901 :
