had been sampled by inspectors in previous seasons. The ap- 

 parent scarcity of this class of feeds and their slow sale seem 

 to indicate that Maine feeders are fully alive to their relatively 

 low feeding value in proportion to the price at which they are 

 sold. 



FLAX SEED BY-PRODUCTS. 



Linseed ]\Ieal is the ground residue after extraction of part 

 of the oil from ground flax seed. In old process meal the oil 

 is extracted by pressure; in new process meal, by naptha. 



Linseed Meal is an excellent high .protein feed, but a com- 

 paratively small amount of it is used in Maine. Inspectors 

 were unable to obtain samples of more than half the brands 

 registered, but those examined make an excellent showing. 

 With the exception of one sample very slightly low in fat, and 

 another very slightly high in fiber, all were strictly in accord 

 with their guarantees. A few of the samples were examined 

 for weed seeds. None were found. 



STARCH FACTORY AND SIMILAR BY-PRODUCTS. 



The starch factory by-products are what are commonly called 

 Gluten Meals and Gluten Feeds. That name is not used for 

 them in the heading above because there is also a brand of 

 distillers grains sold in Maine under the name of "Gluten 

 Feed." Neither starch factory iby-products nor distillers grains 

 have any real right to the name, as neither contain gluten. The 

 makers of the distillers grains in question appear to have as 

 much right to it as the starch factories and to have used it 

 for practically as long a time. 



Gluten Aleal T so-called) is that part of commercial shelled 

 corn that remains after the separation of the larger part of the 

 starch, the germ, and the bran by the processes employed in the 

 manufacture of corn starch and glucose. 



Gluten Feed (so-called) is that part of commercial shelled 

 corn that remains after the separation of the larger part of the 

 starch and the germ, by the processes employed in the manu- 

 facture of corn starch and glucose. (Note that the difterence 

 between the meal and the feed is that the latter contains the 

 corn bran, the feeding value of which is very small).
