Fig. 1. — Showing two methods of placing the wood, brick lined or 

 lathed and plastered silo on a stone foundation. A shows the 

 silo set with upper portion flush with the inside of the stone 

 wall, and B shows the upper portion flush with the outside of 

 the stone wall. A is the right way; B is the wrong way. 



18 to 24 inches thick; It is evident, therefore, that there must be, 

 a shoulder of the wall 12 to 19 inches wide that must project 

 either into the silo pit or outward beyond the sill. 



How to Place the Frame on the Foundation. — Figure 1 Illus- 

 trates two methods of placing the frame on the foundation. A 

 is the right way. B is the wrong way. In B Fig. 1 the shoulder 

 of the foundation wall projects into the silo pit. This method Is 

 permissible when the silo floor Is not more than 1 foot below the 

 top of the wall. If the floor of the silo is three feet or more below 

 the top of the wall as in B Fig. 1, then this shoulder interferes 

 with the proper settling of the silage and the silage molds or 

 rots just above the shoulder next to the silo and usually below 

 the shoulder also. This rotting is commonly ascribed to the loosen- 

 ing of the sill or the foundation allowing air to enter. In most 

 cases, however, it is plainly not due to this cause, but is due to the 

 projecting shoulder which interferes with the settling of the 

 silage. Many silos have been abandoned on this account, so 

 serious has been the loss from rotting. This shoulder should 

 never project into the silo pit. 



Forming the Sill.— The sill may be made of a single 2x4 cut 

 into two foot lengths with the ends beveled so that they may be 

 toe-nailed together to form a circle. Two other methods are also 

 illustrated in Fig. 2, one being a double thickness with broken
