BUILDING THE SILO. 



entire absence of corners in the silo. 3, The tend- 

 ency in the walls to spread is entirely taken away. 

 In the stave silo the hoops when kept properly in 

 place prevent such a result, and in round silos built 

 with a frame the lining within and without has a 

 similar effect. 



Of the two kinds of round silos, viz., that kept 

 in place by hoops, or the silo built with a frame, the 

 Author most unhesitatingly prefers the former and 

 for the following reasons: i, It is more simple in 

 its construction and can be built more economically 

 than the other form of round silo. 2, It is easier to 

 exclude the air, because of the opportunity that is 

 always present to tighten the hoops when necessary. 

 3, It is believed that decay will be less rapid in the 

 stave silo. And 4, Experience has already demon- 

 strated that the frost will penetrate some forms of 

 the round frame silo more easily than a silo made of 

 staves. The advantages of the stave silo therefore 

 over the round silo are so clearly drawn that it would 

 probably be safe to predict that the former though of 

 more recent introduction is likely to almost entirely 

 supersede the latter. Since, however, the round 

 frame silo still has some advocates, it may, be well 

 to give in brief outline the essential features of con- 

 struction in building the same. 



BUILDING THE ROUND FRAME SILO. 



The round frame silo consists of a framework 

 of studding resting on a stone foundation and lined 

 within and without with boards laid over tarred or 

 building paper. The frame rests on wooden sills
