 within the State. All inspectors sent out for this purpose are provided 

 with an authorization signed by the Secretary of the State Board of 

 Agriculture, and only such persons have authorit^^ to collect samples for

COOPERATION WITH THE U. S. DEl'AUTMENT OF AGRICULTURE. 



The Chemist in charge of the feeding stuffs inspection holds a com- 

 mission from the Secretary of Agriculture which gives to the inspectors 

 authority to collect samples of interstate shipments under the Federal 

 Food and Drugs Act. By this means action is secured against the 

 parties responsible for sending low grade or adulterated feed into the 

 State. 



This cooperative arrangement has worked very satisfactorily during 

 the past season when 32 cases were referred to the Federal laboratory at 

 Chicago.
