increase of distance between the hoops until top ones are five feet 

 apart. For tightening these hoops cast iron lugs may be used, or if 

 hardwood is plenty, a very good lug can be made of a 4x6 hardwood 

 timber. 



These may be made to answer for staves by turning them edgewise. 

 They will thus fill four inches as a stave and project four inches on the 

 outside, through which the hoops can be tightened. It is advisable as a mat-

four of these lugs. If three 4x6 's are used the hoops will need to be about 

 19 feet long, three of which will reach around an 18 foot silo. 



OPENINGS. 



Openings should be provided every five or six feet for taking out the 

 silage. They should be sawed on an outward bevel from the inside. The 

 pressure of the silage will cause this door to fit very tightly. A strip of 

 building paper securely tacked over the inside of this, with the silage well 

 tramped against it, will obviate all danger of spoiled silage. 



PAINTING. 



A thick coating of hot coal tar, applied to the inside, will avoid any 

 possibility of the tub leaking air, and will also do much toward preserving 

 the wood.
