In presetting this bulletin to the public, it is the wish of the authors 

 that it be clearly understood that as members of the Agricultural Engineer- 

 ing Staff of the Iowa Agricultural Experiment Station, they do not favor 

 or recommend any one type of silcs above all others. Different types of 

 silos have different characteristics or merits and upon individual circum- 

 stances and conditions will depend the type of silo which should be con- 

 structed. The selection of a silo consists in choosing the type whose 

 characteristics are adapted to the conditions to be met. 



It is the duty of the Agricultural Engineering Staff to furnish definite 

 information in regard to the success, durability and cost of all types of 

 silos as far as possible, and their relation to the various conditions as 

 they may exist.
