WHOLE VOL. APPLIED ENTOMOLOGY HOWARD 145 



soluble forms in lead arsenate must not be equivalent to more tban 

 one per cent of arsenic oxid. It did not allow the addition of water to 

 lead arsenate under certain restrictions. And it did not declare a 

 product adulterated if it contained substances injurious to vegetation. 



At the suggestion of Professor Sanderson, the law was rewritten 

 to cover fungicides, and later a section was added to prevent the sale 

 of insecticides or fungicides that would injure vegetation. 



The law as finally corrected, with the exception of the clause 

 relative to injuring vegetation, was introduced in the Senate of the 

 United States on April 6, 1908, and while the bill was being consid- 

 ered the entomologists, the agricultural chemists, and various manu- 

 facturers met for consultation concerning the provisions of the bill. 

 In its final form it was passed in April. 1910, and became effective on 

 and after the first day of January, 191 1. 



The most important features of the Act are as follows : 



(a) Definite standards for lead arsenates and Paris greens are stated, and 

 it is required that all lead arsenates and Paris greens subject to the act shall 

 conform to these rigid specifications. 



(b) All insecticides and fungicides (other than lead arsenates and Paris 

 greens) which contain inert ingredients shall bear a statement upon the face of 

 the principal label of each and every package giving the name and percentage 

 amount of each and every inert ingredient contained therein and the fact that 

 it is inert, or, in lieu of this, a statement of the name and percentage amount 

 of each and every active ingredient which has insecticidal or fungicidal propertle^, 

 together with the total percentage of inert ingredients. 



(c) For insecticides (other than lead arsenates and Paris greens) and for 

 fungicides which contain arsenic or compounds of this metal, a statement must 

 be made on the face of the principal label of the total arsenic, expressed as per 

 cent of metallic arsenic, and total arsenic in water-soluble forms, similarly 

 expressed. 



(d) No statement, design, or device appearing on the label of an insecticide, 

 fungicide, Paris green or lead arsenate shall be false or misleading in any 

 particular. It will at once be seen that all false or exaggerated claims relative 

 to the efficacy of the article constitute misbranding, and the Government is 

 empowered to institute criminal or seizure proceedings as outlined above. 



(e) All insecticides and fungicides (other than lead arsenates and Paris 

 greens) must be up to the standard under which they are sold. 



(f) No substance or substances shall be contained in any insecticide or 

 fungicide (other than lead arsenates and Paris greens) which shall be injurious 

 to the vegetation on which such articles are intended to be used. 



There are various other requirements, and, in the words of Doc- 

 tor Haywood, "It is by a strict enforcement of these provisions 

 specifically mentioned that the consumer is largely protected against 

 those products which bear misleading claims, which are absolute 

 fakes, and which, while killing insects and fungi, may be injurious to 

 the vegetation on which they are intended to be used."
