.Millers are especially requested to note: 



(1) That Shipstuff is a pure wheat product. 



(2) That SJiorts and MUdlings are the same thing. 



(3) That when Screenings are run in with bran, niiddlings, shipstuff, 

 the resulting jiroduct is no longer bran, middlings, or shipstuff, and 

 should not be so designated; but is a mixture, and should be designated 

 so as to make that <dear, thus: AVlieat Bran and Screenings, Shipstuif 

 and Screenings, or Wheat Bran with Mill Run Screenings, "Wheat Bran 

 with Screenings, not exceeding Mill Bun. 



(4) That S c re ejiings shon\d always be ground to destroy the viability 

 of weed seeds. Weed seeds are usually so small and so hard that they 

 pass through the alimentary canal undigested and become dissiminated 

 in dung over the fields to the detriment of both farmer and miller.

Ash. This is the incombustible part of the plant, earthy matter 

 drawn from the soil by the plants, and taken over into the animal organ-

AXLM.VL FEEDING A>D MTRITION 



A fundamental distinction between plants and animals is this: Plants 

 manufacture, so to speak, foods; animals consume, but cannot manufac- 

 ture, food. They merely transform — more or less modify — the food they 

 get from plants, utilize it for their own growth and nuiintenance and for 

 doing work, or else store it up in their bodies or, as in the case of milk, 

 excrete it. 



Animals get the mineral matter for forming bone from plants, a small 

 portion also from water. The function of the carbohydrates and fats in 

 animal nutrition is the production of warmth and energy; for this pur- 

 pose fat has two and f«nir tenths the value of carbohydrate pound for
