Dr. J. Seward Webb has a 9,000-acre preserve in the Adirondacks, and various other large parks have been established elsewhere, in which our fast-disappearing game animals are augmenting in numbers and game birds of foreign origin have been introduced. The Story of the Building of a Silo[17] What is a Silo? A silo is a place or receptacle for storing green feed to preserve it for future feeding on the farm. In this way green fodder, such as corn and similar crops, are preserved in a green state to be fed in the winter or next summer during an extremely dry season. The silo has the same relation to cattle feed as the glass fruit jar that mother uses has to the food she preserves in it. The First Silo. Silos have been used since very early times in one form or the other, and probably the first we have ever heard of are traceable back in ancient history to the Syrians, who had pits in the ground for the storage of animal feed. These pits have been used in various parts of the Old World ever since and have also been used in the United States. The pit does not give the best results. In order to overcome these defects we soon began to see silos erected above ground. Cement, brick, tile and wood were used as building material, with various results. The industry developed rapidly and soon demonstrated what was necessary to keep the silage pure, sweet, clean and succulent. Science and research have helped, until now we can produce silos that will keep this green fodder in a sweet and succulent state until the owner is ready to use it. What is Put in the Silo? The principal silage crop is corn, but in different parts of the country there are other crops which can be used to great advantage as substitutes for corn. Among these are kaffir corn, sorghum, alfalfa, clover, millet, cowpeas, soy-beans, sugar beets, oats and even weeds and thistles. All of these make good silage when properly harvested and stored. Any green fodder can be mixed with the above to make quantity and secure good results. The main point to be remembered is that the crops to be put away in the silo must contain a certain percentage of sugar and starch in every combination. Elements of Success or Failure.
