..f the 'guaranty would be considered as indicating intent to defraud. W. J. 

 JDSKS. Jr., Imliana Station. 



My main criticism, other than those which are incorporated in the reprint 

 as emanating from me, would be as to 2a. I believe that there should be added a 

 I>n>\ i-ii as follou.-: 



1'roi ulxl, That if there should be a sufficient excess of other ingredients over the 

 LMiaranty statement to make good the commercial equivalent of the promised plant 

 food, the material may not be deemed adulterated." You will notice that I have 

 put the verb in the permissive rather than the mandatory form, so as to leave it in 

 the discretion of the inspecting officer to say whether the proviso should or should not 

 hold in a given case. I should strongly urge, however, before any goods are branded 

 as adulterate.! under this act, that resampling and reanalyzing should be resorted 

 to. .1. !.. HIII.S, Vermont Station. 



\Ve are heartily in favor of the enactment of a national fertilizer-control law, that 

 would furnish a broad, scientific, and economical guide on this subject to state law- 

 makers. The law should provide for actual experiments so that the relative value 

 of plant food from all sources could be accurately shown without prejudice. The 

 state system of fertilizer control is all wrong, for the reason that the men who frame 

 the laws have not a sufficient knowledge of the subject. * * * The great need of 

 both the fertili/er industry and agriculture is positive knowledge without selfish 

 influence or opinions not founded on facts. Terms should not be misleading, and the 

 e from which the plant food is derived should be plainly stated. To leave these 

 <|ui -tions to the officials of the various States and the fertilizer manufacturers is a case 

 .if allowing the tail to \\:i.r the dog, and will prove a very unsatisfactory guide.
