traded by two processes, known as the old process and the 

 new process. In the okl process the oil is simply expressed 

 from the seed by hydraulic pressure. In the new process 

 naphtha or a similar solvent is used to extract the oil. On 

 account of the extraction being more complete when a 

 solvent is used, the new process generally contains less fat 

 than the old process, while they contain about the same 

 per cent, protein. 



WHEAT PRODUCTS. 



Wheat hran is the coarse outer covering of the wheat 

 berry. It contains much of the fibrous material of the 

 grain, but is rich in protein. 



Middlings or sJiorts. These terms have generally the 

 same meaning in the trade, and are the fine particles of 

 the outer bran as well as considerable starchy matter. They 

 are the intermediate product between bran and flour. 



Red dog is a low-grade wheat flour containing the finer 

 particles of bran.* 



Wheat mixed feed or shipstuff is a mixture of the by- 

 products from the milling of the wheat berry.* 



Mixed feed. The term mixed feed has been so generally 

 used to mean a mixture of wheat products that it is practi- 

 cally a misrepresentation to use the term to mean a mix- 

 ture of other cereals. A feed carrying less than fifteen per 

 cent, protein and four per cent, fat cannot be a good mixed 

 feed. 



CORN PRODUCTS. 



Corn hran is the outer coating of the corn kernel.* It 

 has a low feeding value. 



Corn and coh meal is the ground whole ear of corn. In 

 this case the cobs are not considered an adulterant.
