INTRODUCTION. 



This bulletin contains the results of the first year's work under 

 the revised feeding stuffs law which went into effect September 

 1, 1912. There have been collected and examined, since the 

 publication of the previous bulletin, 1115 samples, all of which 

 practically conformed to their guarantees. The year has been 

 considered one of adaptation to new conditions and no prosecu- 

 tions for violations of the law have been made, although where 

 infringement of the statute was noted attention was called to 

 the matter through correspondence and conditions corrected. So 

 far as we were able to ascertain, there were no flagrant violations 

 of the law. 



The text of the new law was published in Bulletin No. 142. 

 Its intent and purpose is to prevent fraud and to insure to the 

 consumer information that will make possible the intelligent 

 selection of commercial feeding stuffs. With this end in view 

 the law requires manufacturers to label their goods in such a way 

 as to make this information available. The guarantee attached 

 to a feeding stuff should not be taken to mean that the feed has 

 exceptional feeding value. Anything not absolutely injurious to 

 animals may be incorporated in a feeding stuff so long as -the 

 guarantee tells the truth. The purchaser should take nothing for 

 granted but should read the guarantee and judge for himself. 

 When in doubt, he should apply to the experiment station for 

 further information. 



It is a commendable fact that, with few exceptions, manu- 

 facturers have been willing to comply fully with the require- 

 ments of the law. A notable exception is found in the case of 

 millers who assume that they have the privilege of incorporating 

 screenings with pure wheat by-products and selling the mixture 

 as wheat bran, wheat middlings or wheat mixed feed. Wheat
