 to our attention, and it has also been referred to this Association, of 

 the presence of tin in certain grades of refuse middlings from the 

 manufacture of tin plate. This difficulty is now being overcome 

 by the use of magnets which takes out all particles of tin which might 

 be present in the product. In order to be absolutely sure, however, 

 that no harm can come from the feeding of this material, the Live- 

 stock Sanitary Board of our Department is conducting a feeding 

 experiment with this feed. It would be well, at this time, to call 

 your attention to the fact that one brand of so called refuse middlings 

 was being sold which contained a large amount of ground peanut 

 hulls, but as the law prohibits the sale of peanut hulls in any feed 

 in the State, we have refused to permit this product to be sold, and 

 therefore, if any of you gentlemen have any doubt as to the character 

 of refuse middlings, it would be well to send samples to the Chief 

 Chemist of the Department who will tell you whether or not any 

 peanut hulls are found in it.
