Aside from certain technical by-products, they are the most available materials for this purpose, and the culture of leguminous feeding crops, both for this purpose and for their effects on the soil, deserves careful consideration. The oil seeds, such as flax, cotton and rape, are not commonly used directly as feeding-stuffs because of their commercial value. These seeds contain a high percentage of proteids, while in place of much of the carbohydrates of the cereals and legumes a large percentage of oil is found. Flax seed contains a considerable quantity of so- called "mucilage," which swells up with water to a slimy mass and has a very soothing effect on the digestive organs. Cotton seed is fed to cattle to some extent, usually either boiled or roasted, but is regarded as dangerous for growing swine. (2) The by-product feeding-stuffs are the resi- dues of technical processes by which the products of the soil are prepared for man's use, either as food or for other purposes. The more important of these technical processes are: (a) The milling of grains; (b) the manufacture of cereal foods; (c) the manufacture of alcoholic liquors ; (d) the manu- facture of starch and glucose ; (e) the manufac- ture of sugar ; (/) the extraction of oils. (a) Milling residues, particularly of wheat, are among the most familiar of the by-product feeding- stuffs. They include the screenings secured in clean- ing the grain for milling and the bran and mid- dlings secured in the grinding proper. The screen- ings are an exceedingly variable mixture according to the quality of the grain, containing, besides light and broken grains, a great variety of weed seeds, fragments of straw, sand and earth, as well as spores of numerous fungi, and dirt of all sorts. While some of these have undoubted feeding value, the possibl
