Concrete Silos 57 



The determination of the particular type of silo to 

 be erected in a given place will depend upon a number 

 of considerations. While there may be several things 

 which in any given locality will point to one type of 

 silo as somewhat more suited to the conditions than 

 another, the principal consideration governing the 

 choice will in most cases be found to be the whim of 

 the owner. It is unfortunate that this is so, but it is 

 one of the conditions to be reckoned with. Aside from 

 this, however, there are logical conditions which will 

 influence, or should influence, the choke of type. Two 

 extreme cases might be cited as illustrating this. 



Suppose, for instance, that there is a good deposit of 

 sand and gravel on a man's farm, and that there is a 

 contractor in a nearby village who has a set of forms 

 for building monolithic silos, and with a reputation for 

 building them well; these conditions would naturally 

 point toward the monolithic silo for this particular loca- 

 tion. On the other hand, suppose another farmer, who 

 has no available deposit of sand and gravel, but who is 

 within convenient hauling distance over good roads 

 from a plant where he can procure structural units of 

 some kind for silo construction. These conditions will 

 as certainly point to the use of such units. 



There will, of course, be many modifications of 

 these conditions, at some time some of them possibly 

 pointing in one direction and some in the other. They 

 will then have to be weighed against each other and 

 the decision made in the direction of those which seem 

 to be most favorable. 



The labor situation may influence the selection 

 somewhat. If stone masons are available and plasterers 

 are not to be had, this would tend to make one favor
