44 Colcord's System of 



The mouth of the vertical pipe g I close with 

 a stopper /, or with a cap. 



If the silo has a capacity of over 150 tons, or 

 is more than fifteen feet deep, the apparatus 

 for the bottom of the silo being in place, the 

 cut corn is piled upon it in the usual way; and, 

 when the silo is about half full, another appa- 

 ratus, or frame A, not differing materially from 

 that on the bottom of the silo, excepting that 

 its vertical pipe m, which performs the same 

 office as the vertical pipe g, and also has its 

 mouth closed by a stopper, rises from the in- 

 side of the silo, as seen in Figure 2. 



For the better support of the second frame 

 A, and to prevent the small holes at the bot- 

 tom of the pipe from becoming stopped with 

 the forage, it is placed on a skeleton plat- 

 form n, Figure 2, composed of narrow strips 

 of furring ; and upon this platform n, with the 

 frame upon it, the cut corn is piled until the 

 silo is filled. To secure the second frame A 

 in its place on the skeleton platform n, nails or 

 staples are driven into the platform for that 

 purpose. As soon as the silo is filled, the ordi- 

 nary planks are put upon the top of the for- 

 age, and the weight placed on said plank. 

 Nothing should be put between the forage 

 and the plank.
