A silo with eight sides of 5 foot each, girded by 2x4 scantling, lapped 

 and spiked at the eight corners. These girders are 16 to 24 inches apart, 

 making thirteen of them for a siio twenty feet high. They are lined up 

 and down inside with common matched pine flooring. 



The material will cost about twenty dollars and will hold sixty tons 

 of ensilage. It is also a very cheap form of grainery or corn crib. 



A larger, and therefore cheaper form, is a tv/elve sided one of 5 foot 

 each, 20 feet high, girded the same as above by 2x4 rough timber lapped 

 and spiked at the corners. 



How to build this silo. Take seventy-eight 2x4, 12 feet long, rougli 

 oak scantling, cut them in the center at a 4 to G inch angle, cut ends at 

 same angle, making short at outside 5 feet 3 inches, and inside 6 feet 3 

 inches long. When all are cut to this mea-sure, level a circle twenty feet 

 in diameter, lay twelve of these pieces around it, each alternate one on 

 the ground, the others lapping at the ends on top. Have the laps all 

 even. Then drive a 20 penny spike in each corner. Square this foun- 

 dation by measuring from each corner to center. Then drive another 

 spike in each corner. This is the foundation. Next, lay twelve more 

 pieces on top of these, but see that the inside edges are plumb with the 

 lower oner, drive two spikes in each corner. Then take a common fence 

 plank, IxG, nail it in the inside corner of the foundation; plumb it each 

 way and brace it. Do the same at every corner. Cut some 2x4 blocks 14 

 inches long; raise one corner of the second girder of 2x4, and place one 

 of these blocks perpendicular between this; girder and the foundation. 

 Raise each corner the same and nail the corner plank to them. Spike 

 another girder together on top of this one, being careful to have the laps 

 at corners plumb at corner edge of upright plank. Knock out the 14 

 inch blocks below and raise this girder with them. Nail as 'nefore. So 

 continue until one-third the height of silo. Then use block 20 to 24 

 inches long. When the desired height is reached, the structure will be 

 the skeleton frame, with temporary corner supports.. Line perpendi- 

 cular with common one-inch matched pine flooring of 8, 10, or 12 foot, or 

 longer lengths. When corner is reached, knock off the fence plank, as its
