The dairy farm presents peculiar problems. The soil must be made to produce those foods that are best fitted to the needs of dairy cattle. Plenty of pure water, grass, and shade in the summer, and grains, hay, and fodder are needed. Silage, made from ground-up corn and corn fodder, is one of the best winter foods for milch cows. The corn is cut in the late summer before it has been deadened by the frost. It is run through a cutter or shredder which crushes leaves, stalks, and ears into little pieces. These the shredder carriers into a silo. This a specially made building, usually round. Here the shredded pieces are tramped down firmly. The preservation of silage depends on keeping the air from it. Therefore, a silo is well built and lined. Some are built of wood bound together by iron hoops. Others are of cement or brick. They are usually built beside the barn

to make feeding easy. Feeding takes place from the top of each day, so but little of the silage is exposed, and that for only a short while. The big shredders tear up loads of corn in a few minutes. There must be some machine in the cornfield that cuts and loads the corn as fast as the shredder handles it. The machine you see here is used for that purpose. It is a corn harvester and elevator combined. It is pulled by horses, so that a big drive wheel furnaces the power to run the machinery. A sickle cuts off the stalks, and these are carried to the top of the elevtor by a revolved canvas. The stalks fall on a wago which is hitched closely to the harvester. One man loads the stalks, while the other drives the wagon. Find out all you can about silos from farmers or farm journals.
