Importance of a Smooth Wall:—In handling the inner forms, great care must be observed in keeping the inside surface of the silo perfectly smooth. Horizontal, "steps" in the wall are particularly- objectionable. Projections, "steps" and other irregularities cause uneven settling of the silage, thus forming air pockets. The presence of an air pocket frequently causes silage within a foot of the pocket on all sides to spoil. Painting the Forms:—The inner surfaces of the forms should be painted before using, with crude oil or whitewash, which will prevent. % rods 4"-5/4 channel Figure 33.

This treatment is especially important where forms have wooden surfaces, but is also beneficial when applied to galvanized iron surfaces. Doorways Continuous and non-continuous doorways are used about equally in monolithic silo construction and the question of which to use is generally settled by personal choice. The continuous doorway has the advantage of providing a larger space through which to throw the silage and for this reason is preferred by many. The non- continuous doorways, as used by some of the best contractors, have no disadvantage except they provide a smaller space through which to remove the silage. Continuous Doorways:—The best kind of a continuous doorway can be made by using two 4-inch 5^4-pound steel channels, of a length 1 foot greater than the distance from the floor of the barn to the top of the silo. Holes large enough to receive 24-inch rods must be. Please note that these images are extracted from scanned page images that may have been digitally enhanced for
