HOW TO BUILD A SILO. 



If the silo is built outside of the barn some sort of a 

 roof is desirable. This should be sufficiently wide to pro- 

 tect the walls of the silo as thoroughly as possible. A 

 very satisfactory roof is shown in Fig. 14. Two other con- 

 structions of a cheap roof for a stave silo are shown in 

 Figs. 18 and 19. The latter was built at the Indiana Ex- 

 periment Station at a total cost of $10.50, viz., lumber 

 $4.00, tin put on and painted $6.00 and hardware 50 cents. 

 Two 2x6 pieces (AA) were placed on edge and toe-nailed 

 to the top of the staves they rested on; the projection is 

 for supporting the carrier at filling time. They are tied 

 together by the short pieces E. The roof is in three 

 sections, G, H, and I. G and H are hinged to the frame 

 A, A, and may be tipped up when the silo is nearly full,
