64 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 protect the 

 walls of the silo as thoroughly as possible. A very satisfactory 

 roof is shown in Pig. 16. Two other constructions of a cheap 

 roof for a stave silo are shown in Figs. 20 and 21. The latter 

 was built at the Indiana Experiment 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, to allow filling 

 to the top. The narrow middle section is light enough to lift 

 off on either side, and leaves the opening for the carrier to 

 deliver into.
