The five products last named are sold largely or exclusively as 

 cattle-foods, either under the above names or under others. 



-Red-dog four is the name given to the poorest grade of flour, so 

 named because it is "off color." 



The term ^''middUngs''' is used by some manufacturers to cover 

 everything except the high-grade flours and bran; in many cases, 

 indeed, a very considerable proportion of bran is included in the 

 product. Shoi'ts and ship-stvff are terms applying to somewhat 

 varying grades of middlings, the former being, in fact, closely re- 

 lated to bran, but containing less fiber and ash. 



The terms mixed feed or wheat feed are applied to mixtures of 

 middlings, bran and other "wheat offals," and. in some instances, 

 are in part composed of "red dog." 



Owing to the wide latitude in the use of the several trade names 

 of milling products, it \s clear that the purchaser can have from the 

 name alone, only a very imperfect idea of the composition and 

 nutritive value of the various wheat offals, especially those sold as 

 middlings and as mixed feed. 



Furthermore, even in the case of brans, the Connecticut and Mas- 

 sachusetts controls have found a considerable amount of adultera- 

 tion, admixtures of corn-cob and w^astes from broom-corn being in- 

 troduced. The latter control states that this was particularly true 

 of certain brans brought from Tennessee and Kentucky. 



The following samples of wheat products were submitted by De- 

 partment agents during the current vear:
