PREFACE 



THE concrete silo has easily demonstrated its 

 superiority over all other types of silo construction, 

 and to-day stands, in the opinion of every practical 

 builder, as the nearest to perfection of any type of 

 structure for the preservation of green crops in si- 

 lage. When we hark back to the civilization of the 

 past centuries, we find that the silo is but another 

 modern adaptation of ancient building construction, 

 bringing more forcibly to our notice "that there is 

 nothing new under the sun." 



In this treatise I have endeavored to show the 

 requirements of silo construction to insure success, 

 and the best methods of complying with these requi- 

 sites when concrete is the material for the struc- 

 ture. The importance of the foundation is fully 

 treated, as the structure can be no stronger than the 

 foundation upon which it rests, and it is far better 

 to err on the safe side in construction of the founda- 

 tion than to find it inadequate for the load it must 

 carry. As the solid wall silo is the usual type erected 

 at the present time in monolithic construction, I 

 have presented one of the most practical and posi- 

 tively the most simple and easily constructed wood 

 form that has been published up to the present time.
