The Construction of a Concrete Block SiIo» 



A. BROOKS, Works Overseer. 



There are several classes of material that can be used for the construction of 

 overground silos ; they are principally stone, brick, wood, or concrete. Each 

 of these has its own recommendations, and the choice depends in a considerable 

 degree on which is the nearest to the farm, and its cost compared with the 

 others. In the opinion of a good many farmers the wood silo turns out the 

 best silage, and concrete the next best, but the point is not one about which 

 ther is entire unanimity. Both stone and brick — unless plastered with 

 cemtnt mortar — absorb a good deal of the moisture in the vegetable material 

 ensiled, and the " cure " is, therefore, not so satisfactory nor the fodder so 

 palatable when ultimately fed to stock.
