ers' grains from corn aud a little more than distillers' grains from 

 rye. In order to thoroughly investigate this matter, the Chief 

 Chemist and General Agent made a trip to the I'eekskill plant of 

 the Fleischmann Company where the product was being prepared. 

 They were received very courteously by the company officials and 

 given every opportunity to determine the character of the product. 

 The result of the investigation showed that the grains were a mix- 

 ture of distillers' dried grains and yeast dried grains; also that a 

 similar product being put out bj'^ another plant in the West, were, 

 instead of being distillers' dried grains, the dried grains from the 

 manufacture of j^east without having mixed with this product the 

 distillers' dried grains. This situation was reported to the officials 

 of the Bureau of Chemistry, in Washington, who also made an in- 

 vestigation of this subject with respect to interstate shipments. The 

 co-operative work between this Department and the United States 

 Department resulted in the question being presented at the Fall 

 meeting of the Feed Control O — cials Association, which Association 

 adopted a definition for the product as follows: "Yeast or Vinegar 

 Dried Grains are the properly dried residue from the mixture of 

 cereals, malt and malt sprouts (sometimes cottonseed meal) ob- 

 tained in the manufacture of yeast or vinegar and consists of corn 

 or corn and rye from which most of the starch has been extracted, 

 together with malt added during the manufacturing process to 

 change the starch to sugar, and malt sprouts (sometimes cottonseed 

 meal) added during the manufacturing process to aid in filtering the 

 residue from the wort and serve as a source of food supply for the 

 yeast." This matter was also taken up directly with the manufac- 

 turers who, after considering the subject, complied with a request of 

 the Department, and registered and re-labeled the product so that 

 these dried grains are now being sold in the State as either "Dis- 

 tillers and Yeast Dried Grains" or "Yeast Dried Grains," as the case 

 may be. 



Another by-product new to the feeding stuffs industry has been in- 

 troduced as an ingredient in mixed feeds which is now being used 

 under its proper name of "Ivory Nut Meal." This product was in- 

 troduced also early in the year under another name; but after the 

 analysis of a few samples and an identification of the product by the 

 Bureau, the true character of the product was learned. This matter 

 was also placed before the Association of Feed Control Officials for 

 the adoption of a definition, with the result that the name "Ivory 

 Nut Meal" is now being used. This product is the ground cuttings 

 from the manufacture of buttons from the ivory nut. The analysis 

 shows it to contain very little protein and fat, but a rather high 

 percentage of carbohydrates which appear to be somewhat diges- 

 tible. As the law does not prohibit the use of this product, no objec- 

 tion could be made to the use of the same as an ingredient in mixed 

 feeds providing it was properly designated. There is only one com- 

 pany using this meal at the present time, and as the supply is lim- 

 ited, it is quite likely there will not be much of it sold in Pennsyl- 

 vania. 



Another product, also new to the feeding stuffs industry, made its 

 appearance, and after an examination and nnalvsis of a number of
