503. Foundation and Sill. Like the brick silo, this form 

 should have a stone foundation, wherever it is practicable 

 to obtain the material for it. Upon this should first be laid 

 the sill made of 2x4's cut in two-foot lengths with the ends 

 beveled so that they may be toe-nailed together and bedded 

 in cement mortar upon the wall in the manner represented 

 in Fig. 201. The sill is set just far enough back from tho 

 inside of the wall so that when the brick are laid they come

 and plastered silo. 



504. Setting Studding. The 2x4 studding are next set 

 up and toe-nailed to the sill. A stud is first set at each angle 

 of the sill, plumbed and stayed from a post set in the center 

 of the silo. After four or five of these are set and plumbed 

 from the center they should be stayed from side to side by 

 tacking to them a strip of half-inch sheeting bent around 

 the outside as high up as a man can reach, taking care to 

 get each stud plumb in 'this direction before staying. After 

 the alternate studs have been set up in this manner the 

 intervening ones may be put in place, toe-nailed to the sill 

 and stayed to the rib holding tho others in place.

 outside layer of sheeting which, for all of the silos less than
