5o MAINU AGRICULTURAI, EXPERIMENT STATION. 19II. 



(Discussion of results of inspection continued from page 47.) 

 probably on account of its high price. Only a few samples 

 were received from dealers and but 7 official samples obtained 

 by the inspector. The analysis of these meals shows that the 

 goods put out by the American Linseed Company run consider- 

 ably above their guarantees, and those by the Guy G. Major 

 Company to be above in all but 2 samples. 



The samples of gluten feeds examined have shown them to 

 be very satisfactory and it was seldom that a sample fell below 

 the guaranty. An average of the results would show them to 

 run considerably above. The practice of coloring, however, 

 has been continued in most instances and, according to the re- 

 quirements of the pure food law, this fact is stated on the 

 package. The practice should be discouraged since it adds 

 nothing to the value of the product and might be used in some 

 instances to conceal inferiority. The acidity of the feeds re- 

 mains about the same and although they are quite acid to the 

 taste they contain practically no free mineral acid. 



Dried distillers' grains for the most part conform very well 

 to their guarantees. It is a more difficult matter to sample 

 these goods than most kinds of feeds and dealers should take 

 great care in this particular when sending samples for analysis. 

 It seems a mistake to call some kinds of distillers' grains gluten 

 feed, as is done in some cases, although they somewhat re- 

 semble the latter in composition. 



The zvheat offals, middlings, mixed feeds, and brans are not 

 required by law to carry a guaranty, but most of the manu- 

 facturers have adopted the plan of guaranteeing protein or 

 both protein and fat, and the plan is a good one. Almost every 

 sample of this class of goods ran above its guaranty. 



The udidterated wheat offals contained ground corn cobs 

 and they, as far as we learned, all carried tags stating their 

 composition with one exception and this case together with two 

 others running below guaranty are being investigated under the 

 National Food and Drug law. It is the fault of the feeder if 

 he buys one of these brands containing only about two-thirds 

 the protein of a good mixed feed because it can be purchased 

 for 5 or 10 cents less per hundred. 



No feeder would think of buying ground corn cobs, which 

 have practically no feeding value, at $1.25 or $1.30 per 100 

 pounds, if put on the market in sacks by themselves, but still
