. Annual report of the Missouri State Board of Agriculture. Missouri. State Board of Agriculture; Agriculture -- Missouri. THE SILO. 411 pole to guide by and brace to. The bottom wall was made thick and tamped against the earth bank. When the level of the ground was reached he carefully leveled up the work and started the outside form, which was made of a band of iron, 20 inches wide and feet long, rolled to form the circle and was fastened with clamps at the ends. The silo being 16 feet in diameter and the walls 6 inches thick, the form is then 17 feet in diameter. This was leveled and the space between it and the inner wall of boards filled with concrete and tamped. When this hardened the form was loosened, raised and screwed tight again after getting it level; the space again filled and so on to the top. The inner wall was raised as needed, being braced against the center pole from all sides. See figure 7. Notice at the top of the silo the iron form still stands surrounding the wall it last built. ¥.
