FARM STRUCTURE 469 Monolithic Silos. The solid wall does not offer serious objections in permitting the freezing of the silage, especially if provided with a good, tight roof. The concrete silo blocks are nearly al- ways made to contain an air space, and double forms may be used in the mon- olithic construction, mak- ing a double wall. When air circulation is restricted in the dead-air space by horizontal partitions about every three feet of height, the double wall is perhaps the most satisfactory, as far as frost-proof qualities are concerned. The cost of a concrete silo will depend largely upon local conditions. The Fis. 295. a cost of sand, gravel, and labor are the deciding factors. Under usual conditions, the cost should not greatly exceed the cost of a first-class wood- en silo. No attempt will be made here to discuss the con- struction of forms. The Hollow Clay Block, or Iowa Silo. In general, this silo consists of a wall of vitrified clay building blocks reinforced with steel laid in the mortar joints. The roof is made of concrete, and the silo has a reinforced concrete door frame. Description of the Blocks. The blocks are hard-burned building blocks, and may now be had curved to the curvature of the silo wall, making a smoother wall on the inside.
