Details of constriictioii are illustrated by four figiu'es. The following 

 suggestions regarding the repair of sdos are taken from the bulletin : 



The matter of vcutilation is tlio first point requiring attention. This can be 

 secured in most of the silos Avliieh have earefiilly constructed dead-air spaces, by 

 removing the upper board next to the plate or by sawing out sections between each 

 l>air of studding. These openings may be covered with netting. 



Where paper has been placed against the side of the barn and strips of furring 

 used to carry the lining, I believe the best way will be to remove the lining, take off 

 the strips of furring, and apply sound lining directly to the paper, putting on new 

 paper where the old is injured. 



Where stone walls have been faced with wood and the lining is rotting, the wood 

 .should all be removed and the wall jdastered so as to be a little more than flush with 

 the lining above, and those silos which have walls which set back under the lining 

 above should be faced out tliish. A jog outward into the silo below is often admis- 

 sible but the reverse never. 



Where only small ])at«lus of lining are rotting it may behest to cut out the rotting 

 wood and j^aiut tlie edges well with carbolic acid or creosote oil to kill tli<' germs. 

 Then fit in a block ami nail over it a jiiece of tin and paint this with a coat of hot, 

 tliick coal tar. 



Where dirt has been banked against the lining it should be removed and tlie bot- 

 tom lowered enough to let the boards become dry when the silage is removed. 



Kottiug silage should not b«' allowed to remain in the silo. When it nnist be left 

 for a time, it sliould be thrown into the center away from the walls. 



The cases of rotting against sills and beams are tlie nuist difiimlt to meet. It is, 

 of course, important to prevent the rotting from extending to the sills, and in sumo 

 of the cases this may be done by jtroviding ventilation behind tlie lining and then 

 removing the lower U feet of lining, facing each stud with a wedge-shaped strip 

 about an inch thick at the bottom, b tting it t-xtend downward across the sill. Then, 

 when the lining is restored and tlie wall below made flush with it, the ventilation 

 will help to i>rotcct both sill and lining.
