It is from these considerations that farmers, and especially stock feeders, recognize the importance of breeding corn for increase of protein content. Purpose of Decreasing the Protein.—On the other hand, there is a demand from the manufacturers of those products which are derived from the starch of corn, such as glucose, gum, dex- trine, syrup, and alcohol, for a corn having a large proportion of carbohydrates and not so rich in protein. The practical effect of decreasing the per cent of protein is to increase the per cent of starch; therefore, for such purposes there should be a place on the market for corn which is bred for decrease of protein 56 lbs corn.

In the photograph the crude fibre is miss- ing, amounting to l-J pounds. Purpose of Increasing the Oil.—The oil of corn has in recent years found such a wide commercial use that under the present market conditions, it has become, pound for pound, by far the most valuable constituent of the grain, and, whereas, formerly in the glucose factories and corn mills the germs containing the oil were almost a waste product, there is now an actual demand on the part of these industries for corn which is richer in oil. It is proposed to meet this demand by breeding corn for increase of oil content. Purpose of Decreasing the Oil.—There is also a practical use for corn with a low oil content. It has been found by investiga- tion that in feeding swine, the oil in the corn tends to produce a soft, flabby quality of flesh, which is very undesirable, especially f
