In this cleaning process a six- or eight-sided cylinder is used, set on a slant of three-fourths to one inch to the running foot. This cylinder is composed of a fine screen for two-thirds its length and a coarser. Fig. 766. Fattening hogs on rape, shown in Fig. The fence is the hurdle 767. screen for the other one-third. The screen revolves at the rate of forty revolutions per minute, requires one-fourth horse-power to run it, and will clean sixty-four to seventy-two bushels of rape seed per hour. The whole apparatus is so set that a strong current of air carries away all dust. When the seed is very dirty the fall per running foot of the cylinder is diminished and the number of revolu- tions per minute doubled. Care must be taken in caring for the seed to prevent attacks of mold and must, and the occur- rence of rancidity in the oil and rape cake or meal. This can be done by being careful not to pile seed in too deep piles and by proper precaution in refining. Feeding. The principal uses of forage rapes are for soiling and pasturage. In the former case the plants are cut with knives or a scythe, and fed to stock in desirable quantities. In the latter case the animals are turned in to harvest the crop for themselves, which, after they become accustomed to it, they do very thoroughly and with a great deal of satis- faction. Rape resembles clover in its composition and should make a good grade of silage, but has not met with success as a silage crop. Whether fed as a soiling crop or pastured, it is a very palatable and valuable feed. Rape has been shown to be a very valu- able feed for fatteninglambs and pigs, and has been fed even to dairy cows with sat- isfactory re- sults, although when so fed it should follow rather than immediately precede the milking period.
