HOW TO BUILD A SILO. 



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 B. 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. 



On the framework B, B, and C, C, cheap sheeting boards 

 are nailed. This is then covered with tin, soldered joints and 

 painted. The sections should be fastened down by means of 

 staples and hooks, or other device; the hooks are used on this 

 one. On the inner edge of G and H, 2x2-inch strips, K, are nailed.
