The official report of the analyses of compound fertilizers and of

 are omitted.

 consumers of fertilizers more forcibly towards a consideration of the 

 particular composition of the different brands of fertilizers offered

 basis for comparison. Explanations are given which may aid the 

 farmer in determining the commercial as distinguished from the agri- 

 cultural value of fertilizing ingredients in the wares offered for sale. 

 There is also a table of the " trade values of fertilizing ingredients in 

 raw materials and chemicals, 1889."
