the value of a deficiency on some other element was hardly just 

 to the purchaser or consumer; there can be no question but 

 what it is eminently fair to the manvifacturer. We should not 

 lose sight of the fact, however, that serious deficiencies or ex- 

 cesses change the essential character of a fertilizer. 



All manufacturers whose goods show serious deficiencies 

 have been advised, and all others are hereby informed, that 

 such conditions must not continue to exist or it will be neces- 

 sary to bring legal action against them as the deficiencies are a 

 direct violation of our fertilizer law. 



As stated above, in the majority of cases in the 



Brands complete fertilizers where a serious deficiency of 



Showing plant food has occurred in one instance, the value 



Commercial of the deficiency has been made up by an 



Shortages. excess of one or both of the other elements, 



so that a commercial shortage in the brand 



did not actually occur. There were, however, among all of the 



complete fertilizers analyzed 35 samples which did not furnish 



an amount of plant food equivalent in money value to the amount 



guaranteed. No mention is made of those brands which show 



a commercial shortage of less than 50 cents per ton. The brands 



showing a commercial shortage of over 50 cents per ton are as 



follows :
