planks from spreading. This makes a very service- 

 able wall, and an inexpensive one, especially where 

 the owner has the gravel at hand. A wall of this 

 kind should be eighteen inches at the bottom, and 

 taper to twelve inches on top, and be built plumb 

 on the inside. 



The Square Wooden Silo. Studding, double 

 boarded on the inside, with building or tarred paper 

 between the boards, is recommended by some. Oth- 

 ers say they rot out quickly. The space between 

 the studding should run up and down and should 

 be well ventilated from the outside. If this precau- 

 tion is taken the boarding will last a number of years. 

 The outside may be covered with single board or 

 double, as the owner may think advisable. 



The Round Silo. This seems to be the favorite 

 plan of late years, and they are constructed in nu- 

 merous ways. Half-inch boards sprung to fit up- 

 right studding, put on double thick, breaking joints, 

 with building or tarred paper between, and clap- 

 boarded outside. 



Others make several circular joists out of inch 

 boards nailed together, and use matched boards 

 for the inside, nailed up and down. 



Stave Silos. This seems to be the favorite of the 

 wooden structures. I have seen many of these stave 

 silos, and the one I would copy is built as follows, on 

 a leveled cement wall, built as shown. Set on end 

 four or six or eight (according to diameter of silo), 

 2X4 inch oak scantlings or other hard wood, 

 planed. Bend the five-eighth inch round steel rods
