ROUND WOODEN SILOS.

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.

 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 

 joints and the other using pieces cut to the curvature of the silo. 

 It will be noted that the latter construction eliminates the air- 

 spaces between the silo and the outer sheeting which are evident 

 in the first two mentioned. These spaces admit air so that the 

 space between the studding is not a dead air space. 



Setting the Studding. The studding of the all-wood round silo 

 need not be greater than 2x4, but they should be set as close 

 together as one foot from center to center, as represented in 

 Fig. 6. This number of studs is not required for strength but 

 they are needed in order to bring the two layers of lining very
