. Concrete silos... CONCRETE SILOS. Concrete Block Silos HOLLOW concrete block silos are popular in all of the northern states and more especially so in sections where the winters are extremely cold. In North Dakota and Minnesota there are scores of block silos in service, these being preferred to silos of any other construction, because of the security against freezing provided by the hollow wall. The cost of concrete block silos is often a trifle more than for those of monolithic construction, although this is not true in a great many cases. The best concrete block silos are those erected by contractors who have made a specialty of this class of work. Good block silos can be put up with home-made blocks and by hMiiie labor. Init where there is a reh'ablc block contractor in the vi- cinity it generally pays, in a saving of time as well as in numerous other ways, to have the work done by persons with previous expe- rience. Examining Blocks:—When the work is done by a contractor, the owner should take the precau- tion of examining the blocks which go into his silo^ rejecting those that are damaged or of an inferior quality. A crack of any size, or broken or crumbly edges, indicate a weakness in the block and make it unsuited for use. Blocks may be tested for their water resisting qualities by placing a small amount of water on the surface and observing whether this remains or is absorbed. A block which read- ily absorbs moisture is obviously unsuited for silo work, which dampness must not penetrate. Warped and distorted blocks should be discarded because of their unsightly appearance. Laying the Blocks:—The foundation already described will give as good satisfaction for the block silo as for the monolithic (see pages 36 and 37 and Figure 25). The top of the footing must be made perfectly level, being tested frequently with a level iDoard. As soon as the footing has sufificiently hardened, the top should then be cleaned off and moistened and a coat of slushy morta
