harvesting and Storage 



191 



" The foundation of the storage house may be in the 

 form of pillars or solid walls and should he of such a 

 height that the floor is about on the level of the bottom 

 of the wagon bed, while the footings should be carried 

 below the frost line or to solid ground. Girders 6 by 

 10 or 8 by 8 inches in size are usually placed on pillars. 



" Where cement, brick or stone foundation walls are 

 built, they should extend 18 to 20 inches above the 

 ground level ; and plates 2 to 3 inches thick and 8 to 10 

 inches wide should be placed on the wall. In using 

 walls for the foundation it is necessary to provide means 

 for ventilation under the house. This can be done by 

 placing small windows in the foundation every 10 to 12 

 feet. Even where solid outside foundation walls are 

 used it is advisable to use pillars for the center supports. 



" The principles 

 of constructing stor- 

 age houses of vari- 

 ous sizes are very 

 much the same ; 

 therefore, only one, 

 the 12 by 16 foot 

 house, will be de- 



scribed (see rig. 

 26). 



" For this small 

 storage house, hav- 

 ing a capacity of 

 400 to 500 bushels, 

 build three rows of 

 pillars, one row under each side and one under the cen- 

 ter of the house. Girders 6 by 10 inches in size are 

 placed on the pillars and on these "2 by 8 inch joists,
