Fifty pounds of this mi.\ture may take the place of the corn silage in the ration, using about four pounds less grain than ordinarily goes with the corn silage. [See Bcati, Broad, p. 212.] 0)7.—The small-seeded variety is preferred for the manufacture of oil. When cold-pressed, a yel- low, sweet oil is secured that is considered equal to olive or almond oil for table use. If this resi- due or " oil-cake" is warm-pressed it yields an oil that is useful for lighting purposes, and for wool- len-dressing, candle- and soap-making. The per- centage of oil ranges from to 28. Medicine.—Sunflower seed also has some medici- nal use. When ground and mixed with other food products and fed to animals it improves their digestion and keeps them in good physical condi- tion. The ground seed is said to be used exten- sively as an important constituent of condition powders and stock-foods. Paper and fiber.—Sunilower stems are used for fuel, though they would make excellent paper stuff and yield a iine fiber if industries were developed thus to utilize them. Commercial status of the crop. Up to this time sunflower seed has been mainly for poultry food and in the manufacture of stock-food. For these purposes the limited amount grown has usually found a ready sale at an aver- age price of about two cents per pound. Sunflow- ers may be grown at about the same cost per acre as corn, but by the methods now employed the har- vesting and threshing of sunflower seed is a rather slow and expensive process, and until better meth- ods and improved machinery for handling the crop are secured, it is not practicable to grow sunflow- ers on a large scale. Literature. The best publication on the sunflower which the writer has seen is Bulletin No. 60 of the Division of Chemistry, United States
