The pit or underground silo is useful in the semi-arid sections and on high locations. Where the ground is low, where irrigation is practiced and where the rainfall is great, seepage water will interfere with its usefulness. The pit silo can be built with common home labor. The cost is very low. When once properly built a pit silo is long lived, it never rots, it never blows down, and the silage never freezes in it during the winter. The pit silo can be filled with an ordinary feed cutter costing only about $60. A 6 H. P. engine is large enough for running the cutter. Several neighbors may own such a cutting outfit and co-operate in filling their silos.
