ENSILAGE. 161 



The bottom and the side of it are then cemented with 

 water lime, and three parts of sharp, cleaai sand, laid at 

 least three inches thick and up the edge and under the sill, 

 which should be safely bedded in the cement, or well mixed 

 mortar of lime and sand, with an equal quantity of the 



cement with the lime. The 

 sill may be eight inches wide 

 and three thick, with a second 

 one laid on this four inches 

 narrower. To secure the foun- 

 dation a bolt is built in the 

 concrete or cement, as shown, 

 with a broad washer on the 

 bottom of it, and this bolt

 timbers of the sills, as shown,

The staves made of dry, sound, 3x4 inch pine, are then 

 set up. They are supported at first by stays in the inside, 

 and outside as well, besides being bolted to the upper part 

 of the sill. The sills are of course cut in rounded sections, 

 to make the circle desired. 



When the staves are set up and secured against falling, 

 a hoop of two-inch iron, half an inch thick, and bent to the 

 curve in a tire setter, as for a tire, is fitted on three feet 

 from the ground supported in any convenient manner in 

 their place, until they are drawn together by bolts and 

 flanges made at each end of each strip. As soon as the first 

 is fitted the next is put in place, four feet above the first 

 one, and secured in the same manner. This is done to the 

 top where the last one is placed four inches from it. 



As the staves are set up, those where the doors will come 

 for emptying or tilling the silo are cut out of each stave in 

 such a way that, being held together by strong bands, they 

 will fit in and may be taken out as may be needed. Or 

 they may be hinged if desired in any convenient way, 

 but opening inside. 



The doors should come between the bands, so that they 

 do not interfere with them in any way. Of course the
